    Assessing the Potential of Sponges (Porifera) as Indicators of Ocean Dissolved Si Concentrations2017Inngår i: Frontiers in Marine Science, E-ISSN 2296-7745, Vol. 4, nr 373Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We explore the distribution of sponges along dissolved silica (dSi) concentration gradients to test whether sponge assemblages are related to dSi and to assess the validity of fossil sponges as a palaeoecological tool for inferring dSi concentrations of the past oceans. We extracted sponge records from the publically available Global Biodiversity Information Facility (GBIF) database and linked these records with ocean physiochemical data to evaluate if there is any correspondence between dSi concentrations of the waters sponges inhabit and their distribution. Over 320,000 records of Porifera were available, of which 62,360 met strict quality control criteria. Our analyses was limited to the taxonomic levels of family, order and class. Because dSi concentration is correlated with depth in the modern ocean, we also explored sponge taxa distributions as a function of depth. We observe that while some sponge taxa appear to have dSi preferences (e.g., class Hexactinellida occurs mostly at high dSi), the overall distribution of sponge orders and families along dSi gradients is not sufficiently differentiated to unambiguously relate dSi concentrations to sponge taxa assemblages. We also observe that sponge taxa tend to be similarly distributed along a depth gradient. In other words, both dSi and/or another variable that depth is a surrogate for, may play a role in controlling sponge spatial distribution and the challenge is to distinguish between the two. We conclude that inferences about palaeo-dSi concentrations drawn from the abundance of sponges in the stratigraphic records must be treated cautiously as these animals are adapted to a great range of dSi conditions and likely other underlying variables that are related to depth. Our analysis provides a quantification of the dSi ranges of common sponge taxa, expands on previous knowledge related to their bathymetry preferences and suggest that sponge taxa assemblages are not related to particular dSi conditions.

    Challenges in assessing the health risks of consuming vegetables in metal-contaminated environments2018Inngår i: Environment International, ISSN 0160-4120, E-ISSN 1873-6750, Vol. 113, s. 269-280Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A great deal of research has been devoted to the characterization of metal exposure due to the consumption of vegetables from urban or industrialized areas. It may seem comforting that concentrations in crops, as well as estimated exposure levels, are often found to be below permissible limits. However, we show that even a moderate increase in metal accumulation in crops may result in a significant increase in exposure. We also highlight the importance of assessing exposure levels in relation to a regional baseline. We have analyzed metal (Pb, Cd, As) concentrations in nearly 700 samples from 23 different vegetables, fruits, berries and mushrooms, collected near 21 highly contaminated industrial sites and from reference sites. Metal concentrations generally complied with permissible levels in commercial food and only Pb showed overall higher concentrations around the contaminated sites. Nevertheless, probabilistic exposure assessments revealed that the exposure to all three metals was significantly higher in the population residing around the contaminated sites, for both low-, median- and high consumers. The exposure was about twice as high for Pb and Cd, and four to six times as high for As. Since vegetable consumption alone did not result in exposure above tolerable intakes, it would have been easy to conclude that there is no risk associated with consuming vegetables grown near the contaminated sites. However, when the increase in exposure is quantified, its potential significance is harder to dismiss – especially when considering that exposure via other routes may be elevated in a similar way.

    The 3D biogeochemical marine mercury cycling model MERCY v2.0 – linking atmospheric Hg to methylmercury in fish2023Inngår i: Geoscientific Model Development, ISSN 1991-959X, E-ISSN 1991-9603, Vol. 16, nr 9, s. 2649-2688Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Mercury (Hg) is a pollutant of global concern. Due to anthropogenic emissions, the atmospheric and surface ocean Hg burden has increased substantially since preindustrial times. Hg emitted into the atmosphere gets transported on a global scale and ultimately reaches the oceans. There it is transformed into highly toxic methylmercury (MeHg) that effectively accumulates in the food web. The international community has recognized this serious threat to human health and in 2017 regulated Hg use and emissions under the UN Minamata Convention on Mercury. Currently, the first effectiveness evaluation of the Minamata Convention is being prepared, and, in addition to observations, models play a major role in understanding environmental Hg pathways and in predicting the impact of policy decisions and external drivers (e.g., climate, emission, and land-use change) on Hg pollution. Yet, the available model capabilities are mainly limited to atmospheric models covering the Hg cycle from emission to deposition. With the presented model MERCY v2.0 we want to contribute to the currently ongoing effort to improve our understanding of Hg and MeHg transport, transformation, and bioaccumulation in the marine environment with the ultimate goal of linking anthropogenic Hg releases to MeHg in seafood.

    Here, we present the equations and parameters implemented in the MERCY model and evaluate the model performance for two European shelf seas, the North and Baltic seas. With the model evaluation, we want to establish a set of general quality criteria that can be used for evaluation of marine Hg models. The evaluation is based on statistical criteria developed for the performance evaluation of atmospheric chemistry transport models. We show that the MERCY model can reproduce observed average concentrations of individual Hg species in water (normalized mean bias: HgT 17 %, Hg0 2 %, MeHg −28 %) in the two regions mentioned above. Moreover, it is able to reproduce the observed seasonality and spatial patterns. We find that the model error for HgT(aq) is mainly driven by the limitations of the physical model setup in the coastal zone and the availability of data on Hg loads in major rivers. In addition, the model error in calculating vertical mixing and stratification contributes to the total HgT model error. For the vertical transport we find that the widely used particle partitioning coefficient for organic matter of log(kd)=5.4 is too low for the coastal systems. For Hg0 the model performance is at a level where further model improvements will be difficult to achieve. For MeHg, our understanding of the processes controlling methylation and demethylation is still quite limited. While the model can reproduce average MeHg concentrations, this lack of understanding hampers our ability to reproduce the observed value range. Finally, we evaluate Hg and MeHg concentrations in biota and show that modeled values are within the range of observed levels of accumulation in phytoplankton, zooplankton, and fish. The model performance demonstrates the feasibility of developing marine Hg models with similar predictive capability to established atmospheric chemistry transport models. Our findings also highlight important knowledge gaps in the dynamics controlling methylation and bioaccumulation that, if closed, could lead to important improvements of the model performance.

    Mercury Sources and Fate in a Large Brackish Ecosystem (the Baltic Sea) Depicted by Stable Isotopes2023Inngår i: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Identifying Hg sources to aquatic ecosystems and processes controlling the levels of monomethylmercury (MMHg) is critical for developing efficient policies of Hg emissions reduction. Here we measured Hg concentrations and stable isotopes in sediment, seston, and fishes from the various basins of the Baltic Sea, a large brackish ecosystem presenting extensive gradients in salinity, redox conditions, dissolved organic matter (DOM) composition, and biological activities. We found that Hg mass dependent fractionation (Hg-MDF) values in sediments mostly reflect a mixing between light terrestrial Hg and heavier industrial sources, whereas odd Hg isotope mass independent fractionation (odd Hg-MIF) reveals atmospheric inputs. Seston presents intermediate Hg-MDF and odd Hg-MIF values falling between sediments and fish, but in northern basins, high even Hg-MIF values suggest the preferential accumulation of wet-deposited Hg. Odd Hg-MIF values in fish indicate an overall low extent of MMHg photodegradation due to limited sunlight exposure and penetration but also reveal large spatial differences. The photodegradation extent is lowest in the central basin with recurrent algal blooms due to their shading effect and is highest in the northern, least saline basin with high concentrations of terrestrial DOM. As increased loads of terrestrial DOM are expected in many coastal areas due to global changes, its impact on MMHg photodegradation needs to be better understood and accounted for when predicting future MMHg concentrations in aquatic ecosystems.

    Sources of riverine mercury across the Mackenzie River Basin; inferences from a combined Hg C isotopes and optical properties approach2022Inngår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 806, s. 150808-150808, artikkel-id 150808Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Arctic terrestrial environment harbors a complex mosaic of mercury (Hg) and carbon (C) reservoirs, some of which are rapidly destabilizing in response to climate warming. The sources of riverine Hg across the Mackenzie River basin (MRB) are uncertain, which leads to a poor understanding of potential future release. Measurements of dissolved and particulate mercury (DHg, PHg) and carbon (DOC, POC) concentration were performed, along with analyses of Hg stable isotope ratios (incl. ∆199Hg, d202Hg), radiocarbon content (∆14C) and optical properties of DOC of river water. Isotopic ratios of Hg revealed a closer association to terrestrial Hg reservoirs for the particulate fraction, while the dissolved fraction was more closely associated with atmospheric deposition sources of shorter turnover time. There was a positive correlation between the ∆14C-OC and riverine Hg concentration for both particulate and dissolved fractions, indicating that waters transporting older-OC (14C-depleted) also contained higher levels of Hg. In the dissolved fraction, older DOC was also associated with higher molecular weight, aromaticity and humic content, which are likely associated with higher Hg-binding potential. Riverine PHg concentration increased with turbidity and SO4 concentration. There were large contrasts in Hg concentration and OC age and quality among the mountain and lowland sectors of the MRB, which likely reflect the spatial distribution of various terrestrial Hg and OC reservoirs, including weathering of sulfate minerals, erosion and extraction of coal deposits, thawing permafrost, forest fires, peatlands, and forests. Results revealed major differences in the sources of particulate and dissolved riverine Hg, but nonetheless a common positive association with older riverine OC. These findings reveal that a complex mixture of Hg sources, supplied across the MRB, will contribute to future trends in Hg export to the Arctic Ocean under rapid environmental changes.

    Deltaproteobacteria andSpirochaetes-Like Bacteria AreAbundant Putative MercuryMethylators in Oxygen-DeficientWater and Marine Particles in theBaltic Sea2020Inngår i: Frontiers in Microbiology, E-ISSN 1664-302X, s. 1-11, artikkel-id 574080Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Methylmercury (MeHg), a neurotoxic compound biomagnifying in aquatic food webs, can be a threat to human health via fish consumption. However, the compositionand distribution of the microbial communities mediating the methylation of mercury (Hg) to MeHg in marine systems remain largely unknown. In order to fill this knowledge gap, we used the Baltic Sea Reference Metagenome (BARM) dataset to study the abundance and distribution of the genes involved in Hg methylation (the hgcAB gene cluster). We determined the relative abundance of the hgcAB genes and their taxonomic identity in 81 brackish metagenomes that cover spatial,seasonal and redox variability in the Baltic Sea water column. The hgcAB genes were predominantly detected in anoxic water, but some hgcAB genes were alsodetected in hypoxic and normoxic waters. Phylogenetic analysis identified putative Hg methylators within Deltaproteobacteria, in oxygen-deficient water layers, but also Spirochaetes-like and Kiritimatiellaeota-like bacteria. Higher relative quantities of hgcAB genes were found in metagenomes from marine particles compared to free-living communities in anoxic water, suggesting that such particles are hotspot habitats for Hg methylators in oxygen-depleted seawater. Altogether, our work unveils the diversityof the microorganisms with the potential to mediate MeHg production in the BalticSea and pinpoint the important ecological niches for these microorganisms within themarine water column.

    Oxygen‐deficient water zones in the Baltic Sea promote uncharacterized Hg methylating microorganisms in underlying sediments2022Inngår i: Limnology and Oceanography, ISSN 0024-3590, E-ISSN 1939-5590, Vol. 67, s. 135-146Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human-induced expansion of oxygen-deficient zones can have dramatic impacts on marine systems and itsresident biota. One example is the formation of the potent neurotoxic methylmercury (MeHg) that is mediated bymicrobial methylation of inorganic divalent Hg (HgII) under oxygen-deficient conditions. A negative consequenceof the expansion of oxygen-deficient zones could be an increase in MeHg production due to shifts in microbialcommunities in favor of microorganisms methylating Hg. There is, however, limited knowledge about Hg-methylatingmicrobes, i.e., those carrying hgc genes critical for mediating the process, from marine sediments. Here, weaim to study the presence of hgc genes and transcripts in metagenomes and metatranscriptomes from four surfacesediments with contrasting concentrations of oxygen and sulfide in the Baltic Sea. We show that potential Hgmethylators differed among sediments depending on redox conditions. Sediments with an oxygenated surface featuredhgc-like genes and transcripts predominantly associated with uncultured Desulfobacterota (OalgD group)and Desulfobacterales (including Desulfobacula sp.) while sediments with a hypoxic-anoxic surface included hgccarryingVerrucomicrobia, unclassified Desulfobacterales, Desulfatiglandales, and uncharacterized microbes. Ourdata suggest that the expansion of oxygen-deficient zones in marine systems may lead to a compositional changeof Hg-methylating microbial groups in the sediments, where Hg methylators whose metabolism and biology havenot yet been characterized will be promoted and expand.

    Expression Levels of hgcAB Genes and Mercury Availability Jointly Explain Methylmercury Formation in Stratified Brackish Waters2022Inngår i: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Neurotoxic methylmercury (MeHg) is formed by microbial methylation of inorganic divalent Hg (HgII) and constitutes severe environmental and human health risks. The methylation is enabled by hgcA and hgcB genes, but it is not known if the associated molecular-level processes are rate-limiting or enable accurate prediction of MeHg formation in nature. In this study, we investigated the relationships between hgc genes and MeHg across redox-stratified water columns in the brackish Baltic Sea. We showed, for the first time, that hgc transcript abundance and the concentration of dissolved HgII-sulfide species were strong predictors of both the HgII methylation rate and MeHg concentration, implying their roles as principal joint drivers of MeHg formation in these systems. Additionally, we characterized the metabolic capacities of hgc+ microorganisms by reconstructing their genomes from metagenomes (i.e., hgc+ MAGs), which highlighted the versatility of putative HgII methylators in the water column of the Baltic Sea. In establishing relationships between hgc transcripts and the HgII methylation rate, we advance the fundamental understanding of mechanistic principles governing MeHg formation in nature and enable refined predictions of MeHg levels in coastal seas in response to the accelerating spread of oxygen-deficient zones.

    What’s the catch with lumpsuckers? A North Atlantic study of seabird bycatch in lumpsucker gillnet fisheries2019Inngår i: Biological Conservation, ISSN 0006-3207, E-ISSN 1873-2917, Vol. 240, artikkel-id 108278Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Worldwide, incidental bycatch in fisheries is a conservation threat to many seabird species. Although knowledge on bycatch of seabirds has increased in the last decade, most stems from longline fisheries and the impacts of coastal gillnet fisheries are poorly understood. Gillnet fishing for North Atlantic lumpsucker (Cyclopterus lumpus) is one such fishery. We collated and synthesized the available information on seabird bycatch in lumpsucker gillnet fisheries across the entire geographical range to estimate and infer the magnitude of their impact on the affected seabird populations. Most birds killed were diving ducks, cormorants and auks, and each year locally high numbers of seabirds were taken as bycatch. We found large differences in bycatch rates among countries. The estimated mean bycatch in Iceland was 2.43 birds/trip, while the estimates in Norway was 0.44 and 0.39 birds/trip, respectively. The large disparities between estimates might reflect large spatial differences in bycatch rates, but could partly also arise due to distinctions in data recorded by onboard inspectors (Iceland), self-administered registration (Norway) and direct observations by cameras (Denmark). We show that lumpsucker gillnet fisheries might pose a significant risk to some populations of diving seabirds. However, a distinct data deficiency on seabird bycatch in terms of spatio-temporal coverage and the age and origins of the birds killed, limited our abilities to fully assess the extent and population consequences of the bycatch. Our results highlight the need for a joint effort among countries to standardize monitoring methods to better document the impact of these fisheries on seabirds.

    Silica uptake and release in live and decaying biomass in a northern hardwood forest2016Inngår i: Ecology, ISSN 0012-9658, E-ISSN 1939-9170, Vol. 97, nr 11, s. 3044-3057Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In terrestrial ecosystems, a large portion (20-80%) of the dissolved Si (DSi) in soil solution has passed through vegetation. While the importance of this terrestrial Si filter is generally accepted, few data exist on the pools and fluxes of Si in forest vegetation and the rate of release of Si from decomposing plant tissues. We quantified the pools and fluxes of Si through vegetation and coarse woody debris (CWD) in a northern hardwood forest ecosystem (Watershed 6, W6) at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire, USA. Previous work suggested that the decomposition of CWD may have significantly contributed to an excess of DSi reported in stream-waters following experimental deforestation of Watershed 2 (W2) at the HBEF. We found that woody biomass (wood+bark) and foliage account for approximately 65% and 31%, respectively, of the total Si in biomass at the HBEF. During the decay of American beech (Fagus grandifolia) boles, Si loss tracked the whole-bole mass loss, while yellow birch (Betula alleghaniensis) and sugar maple (Acer saccharum) decomposition resulted in a preferential Si retention of up to 30% after 16yr. A power-law model for the changes in wood and bark Si concentrations during decomposition, in combination with an exponential model for whole-bole mass loss, successfully reproduced Si dynamics in decaying boles. Our data suggest that a minimum of 50% of the DSi annually produced in the soil of a biogeochemical reference watershed (W6) derives from biogenic Si (BSi) dissolution. The major source is fresh litter, whereas only similar to 2% comes from the decay of CWD. Decay of tree boles could only account for 9% of the excess DSi release observed following the experimental deforestation of W2. Therefore, elevated DSi concentrations after forest disturbance are largely derived from other sources (e.g., dissolution of BSi from forest floor soils and/or mineral weathering).

    Arctic mercury cycling2022Inngår i: Nature Reviews Earth & Environment, E-ISSN 2662-138XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels, which are now being impacted by regional warming, with uncertain ecological consequences. This Review presents a comprehensive assessment of the present-day total Hg mass balance in the Arctic. Over 98% of atmospheric Hg is emitted outside the region and is transported to the Arctic via long-range air and ocean transport. Around two thirds of this Hg is deposited in terrestrial ecosystems, where it predominantly accumulates in soils via vegetation uptake. Rivers and coastal erosion transfer about 80 Mg year−1 of terrestrial Hg to the Arctic Ocean, in approximate balance with modelled net terrestrial Hg deposition in the region. The revised Arctic Ocean Hg mass balance suggests net atmospheric Hg deposition to the ocean and that Hg burial in inner-shelf sediments is underestimated (up to >100%), needing seasonal observations of sediment-ocean Hg exchange. Terrestrial Hg mobilization pathways from soils and the cryosphere (permafrost, ice, snow and glaciers) remain uncertain. Improved soil, snowpack and glacial Hg inventories, transfer mechanisms of riverine Hg releases under accelerated glacier and soil thaw, coupled atmosphere–terrestrial modelling and monitoring of Hg in sensitive ecosystems such as fjords can help to anticipate impacts on downstream Arctic ecosystems.

    Evaluation of different stable isotope methods to estimate trophic position of perch (Perca fluviatilis) in Swedish lakes2019Rapport (Annet vitenskapelig)
    Abstract [en]

    The Water Framework Directive (WFD) requires member states to implement a strategy to meet the environmental quality standards (EQS) set by the WFD for a number of priority substances. Since the EQSs listed in the WFD are derived to protect the most sensitive species in the ecosystem, often top predators or humans, it has been decided that for certain priority substances the quality standards should be compared to a monitoring species with a trophic position (TP) similar to the diet of the most sensitive species. To enable such adjustment require both knowledge about the monitoring species TP in the food web as well as the relationship between contaminant concentration and trophic position. In this study, we focus on finding a suitable method for TP estimates of perch in Swedish lakes by evaluating both traditional stable isotope analysis in bulk samples (BSIA) using different baseline matrices and the more recent development of compound-specific stable isotope analysis in amino acids (CSIA-AA). For this, three representative monitoring lakes were selected in which perch together with potential baseline matrices (bivalves, gastropods and sediment) were sampled. We applied triple-isotope analyses, d15N, d13C and d34S, of bulk material of all sampled matrices, and in addition d15N in perch using CSIA-AA. Results showed that TP estimates derived from CSIA-AA were significantly (p<0.001) lower compared to all the BSIA-derived methods and further that the BSIA-derived TP estimates using gastropods as a baseline were significantly higher (p<0.001) than all other TP estimates. Since no statistical differences could be detected between TP estimates based on bivalves, sediment or a ‘mixture’ baseline these were assumed to produce similar results and therefore all valid baseline matrices for TP estimates of perch in these three lakes. In the present study we also attempted to adjust mercury contaminant data to a specific TP of 3.5 according to the WFD. The adjustment resulted in significantly different concentration for one of the two tested lakes but did not influence the chemical status classification as all lakes were well above the threshold for mercury in freshwater lakes.

    Screening for pharmaceuticals, phthalates and polycyclic aromatic hydrocarbons (PAHs) in bivalves sampled along the Swedish coast2019Rapport (Annet vitenskapelig)
    Abstract [en]

    Within the Swedish National Monitoring Programme for Contaminants in marine biota, a selection of the wide array of contaminants that can be found in the environment is analysed. Analysing the samples for all possible contaminants would hardly be feasible, however, screening for different substance groups is a way to investigate if and where new substances arise and may pose a threat to wildlife and humans. In this report, data from a spatial screening study is presented, which aimed to densify the ongoing Swedish National Monitoring Programme for Contaminants in marine biota with regard to pharmaceuticals, phthalates and polycyclic aromatic hydrocarbons (PAHs). The study includes 16 sampling sites along the Swedish coast, from where two different species of bivalves, Limecola balthica and Mytilus edulis, were collected. All applied sampling material in this screening study originates from the Swedish Environmental Specimen Bank of the Swedish Museum of Natural History. The screening included a total of 100 pharmaceuticals, out of which 17 were detected and quantified in at least one sampling site. Risperidone was the pharmaceutical detected at most sites (10 of 13). The only detected phthalate was di(2-ethylhexyl) phthalate (DEHP), which was found in the samples from 3 of 13 sampling sites. Among the PAHs, Benzo(a)pyrene was the substance quantified at most sites (14 out of 16). No geographical patterns could be identified for the detected contaminants, besides for the PAHs. However, this pattern could also be due to a difference in species rather than due to location. PAHs could be detected in the Bothnian Sea and the Sea of Åland, where to date no mussel sampling sites exist within the Swedish National Monitoring Programme for Contaminants in marine biota. The Baltic clam might be a good additional monitoring species besides the Blue mussel, due to their difference in feeding strategy and the potential higher PAH uptake from contaminated sediments rather than the water phase.

    Per- and polyfluoroalkyl substances (PFAS) in white-tailed sea eagle eggs from Sweden: Temporal trends (1969-2021), spatial variations, fluorine mass balance, and suspect screening2023Inngår i: Environmental Science: Processes & Impacts, ISSN 2050-7887, E-ISSN 2050-7895Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Temporal and spatial trends of 15 per- and polyfluoroalkyl substances (PFAS) were determined in white-tailed sea eagle (WTSE) eggs (Haliaeetus albicilla) from two inland and two coastal regions of Sweden between 1969 and 2021. PFAS concentrations generally increased from ∼1969 to ∼1990s–2010 (depending on target and site) and thereafter plateaued or declined, with perfluorooctane sulfonamide (FOSA) and perfluorooctane sulfonate (PFOS) declining faster than most perfluoroalkyl carboxylic acids (PFCAs). The net result was a shift in the PFAS profile from PFOS-dominant in 1969–2010 to an increased prevalence of PFCAs over the last decade. Further, during the entire period higher PFAS concentrations were generally observed in coastal populations, possibly due to differences in diet and/or proximity to more densely populated areas. Fluorine mass balance determination in pooled samples from three of the regions (2019–2021) indicated that target PFAS accounted for the vast majority (i.e. 81–100%) of extractable organic fluorine (EOF). Nevertheless, high resolution mass-spectrometry-based suspect screening identified 55 suspects (31 at a confidence level [CL] of 1–3 and 24 at a CL of 4–5), of which 43 were substances not included in the targeted analysis. Semi-quantification of CL ≤ 2 suspects increased the identified EOF to >90% in coastal samples. In addition to showing the impact of PFAS regulation and phase-out initiatives, this study demonstrates that most extractable organofluorine in WTSE eggs is made up of known (legacy) PFAS, albeit with low levels of novel substances.

    Diatom floristic change and lake paleoproduction as evidence of recent eutrophication in shallow lakes of the midwestern USA2015Inngår i: Journal of Paleolimnology, ISSN 0921-2728, E-ISSN 1573-0417, Vol. 53, nr 1, s. 17-34Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Intensive agricultural practices can dramatically change the landscape, thereby increasing the concentrations and rates at which nutrients are delivered to aquatic ecosystems. In the United States, concerns about accelerating rates of lake eutrophication related to increases in nutrient loading require a method of quantifying ecological changes that have occurred since European settlement. Because the application of traditional quantitative total phosphorus transfer functions in paleolimnology has proven difficult in shallow, hypereutrophic lakes, we used several approaches in this study to assess ecosystem changes associated with eutrophication of 32 natural lakes in the state of Iowa, USA. In addition to traditional transfer function methods, we estimated changes in primary productivity from the flux of biogenic silica (BSi) and organic carbon accumulation rates (OC AR). Additionally, we compared pre-disturbance diatom communities to modern diatom communities, i.e. floristic change, using non-metric multi-dimensional scaling and square chord distance. OC AR and BSi fluxes increased over time and were positively correlated with the time period of agricultural intensification in the region (post-1940). Ninety-one percent of the lakes in this study showed evidence for eutrophication based on geochemical proxies, and 88 % of lakes showed major floristic change in the diatom community. Whereas geochemical indicators showed consistent increases in productivity across most lakes, floristic changes reflected more complex interactions between other environmental drivers. The magnitude of floristic change did not directly correlate to nutrient-driven increases in primary production, but was driven by ecological diatom assembly related to lake depth. Transfer functions consistently perform poorly, especially for shallow lakes, and other techniques that combine geochemistry and diatom ecology are recommended for reconstructions of eutrophication.

    Rapportering från undersökning av trofinivå hos havsörn - stabila isotoper och miljögifter: Överenskommelse Nr 2213-13-0292016Rapport (Annet vitenskapelig)
    Abstract [sv]

    Höga koncentrationer av PCB och DDE har konstaterats i ägg från fem havsörnshonor vid Norrlands-kusten. Möjliga förklaringar kan vara regional förorening, eller att vissa örnar lever på en högre nivå i en näringskedja där koncentrationerna ökar i varje steg. Denna rapport redovisar resultat från analyser av PCB, DDE, HCB och stabila isotoper (SI) (δ15N, δ13C) i muskel från fiskar (fyra lokaler), skarvar (tre lokaler), ägg från skarv (tre lokaler) och havsörn (två lokaler) i Västernorrlands län, och SI i ägg och fjädrar från havsörn i olika biotoper vid Östersjökusten. PCB, DDE, HCB i fiskar visade inte påtagligt högre koncentrationer än vad som rapporterats från Norrlandskusten i övrigt, men hade högre värden för PCB och HCB än vid Kvädöfjärden, Holmöarna och Örefjärden, som används som referenslokaler längs Östersjökusten inom den nationella miljöövervakningen. Koncentrationerna i muskel från skarvungar jämfört med muskel från abborre på lipidbasis var ca 3-7 ggr högre för DDE och upp till två resp. tre ggr högre för HCB och PCB (CB-153). I skarvägg jämfört med abborre var förhöjningen av koncentrationer 30-400 ggr för DDE, 30-140 ggr för PCB och 7-30 ggr för HCB. Koncentrationer av DDE och PCB (CB-153) i de högbelastade havsörnsäggen från Västernorrland var 20 respektive 40 ggr högre än i skarväggen. Hos havsörn ses en tydlig trend för både ägg och fjädrar för δ13C, som blir tyngre ju mer marin fyndplatsen antagits vara, men ingen trend för δ15N. En stegvis ökning ses för δ15N i muskelprover från olika fiskar till skarvungar och skarvägg, dock inte vidare till havsörnsägg, men däremot till havsörnsfjädrar. Avsaknaden av skillnad i δ15N mellan skarv- och havsörnsägg indikerar att de inte är jämförbara med avseende på trofiska nivåer. Statistiskt signifikanta men relativt svaga samband ses mellan koncentrationer av DDE och PCB och δ15N i hela materialet av havsörnsägg. Havsörn är på högre trofisk nivå än skarv men δ15N i örnäggen som läggs redan i mars avspeglar troligen ett inslag av däggdjurskadaver under vintern, medan fjädrarna avspeglar sommarfödan (mest fisk och fågel). Möjligheten kvarstår att högre miljögiftshalter i äggen hos vissa havsörnar kan bero på högre trofisk nivå men detta bör undersökas på fjädrar.

    Rapportering från undersökning av DDT-PCB-HCB-HCH,PBDE-HBCD, PFAS och stabila isotoper i ägg från havsörn2015: Överenskommelse Nr 2213-15-0192016Rapport (Annet vitenskapelig)
    Abstract [sv]

    Sambandet mellan havsörnens reproduktion och miljögifter har studerats fortlöpande sedan 1960-talet.Denna rapport redovisar analyser av 22 okläckta ägg insamlade i samband med bokontroller inom NMÖ,RMÖ samt Projekt Havsörn 2015. Syftet med rapporten är att redogöra för årets analyser i jämförelsemed resultat från perioden 2010-2014, med fokus på att klargöra geografiska mönster. Årets resultat är istort jämförbara med de senaste åren. Ägg från kusten har i genomsnitt 2-5 – 4.5 gånger högre halter änägg från inlandsbeståndet. Under perioden 2009-2015 har havsörnsövervakningen återigenuppmärksammat uttorkade ägg och höga halter av miljögifter i Norra Bottenhavet (Västernorrlands länsamt norra Gävleborgs län). Norra Bottenhavets kustzon avviker tydligt från resten av Östersjön och har1.5 – 4.5 gånger högre halter av miljögifter än övriga Östersjön. 2015 analyserades ett ägg från en nylokal i Timrå-trakten med liknande halter jämfört med tidigare provtagningar från Sundsvall ochKramfors. Det är dock en liten del av beståndet i Norra Bottenhavet som förefaller lägga uttorkade äggmed höga miljögiftshalter.Generellt är korrelationerna mellan olika miljögifter i ägg analyserade 2010-2015 mycket starka ochpositiva. PFAS (perfluorerade ämnen) inkluderades i analysprotokollet 2015, och var korrelerade tillövriga miljögifter. Perfluorerade ämnen samt bromerade ämnen (PBDE och HBCD) bör därföranalyseras framöver om resurser finns. Stabila isotoper har analyserats (kol, kväve) och det finns entydlig signal som särskiljer limniska från marina miljöer. Däremot är korrelationerna mellan miljögifter ochisotopvärden svaga. När det gäller isotoper bör fler prover analyseras på fjädrar från ungar.

    Abstract [en]

    Fungi in subsurface and underground environments is a rather new and underexplored field within mycology, and our understanding of these communities are sparse. However, available reports indicate a high fungal diversity with a large poriton of undescribed taxa in these settings. Here we investigate the fungal presence in the Falun copper mine, Sweden, with the aim to identify fungi useable in bioremediation processes. Thirteen of fourteen samples were successfully cultured, and nine isolates obtained in total. Further culturing and investigations are needed to understand the bioremediation abilities among the fungi, but this first reort indicates a high abundance and diversity of fungi in the underground Falun copper mine.

    Concentrations of 45 Per- and Polyfluoroalkyl Substances in North American River Otters (Lontra canadensis) from West Virginia, USA2024Inngår i: Environmental Science and Technology, ISSN 0013-936X, E-ISSN 1520-5851, Vol. 58, nr 4, s. 2089-2101Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    North American river otters (Lontra canadensis) aretop predators in riverine ecosystems and are vulnerable to per- andpolyfluoroalkyl substance (PFAS) exposure. Little is known aboutthe magnitude of exposure and tissue distribution of PFAS in riverotters. We measured 45 PFAS in various tissues of 42 river otterscollected from several watersheds in the state of West Virginia,USA. The median concentrations of ΣAll (sum concentration of45 PFAS) varied among tissues in the following decreasing order:liver (931 ng/g wet weight) > bile > pancreas > lung > kidney >blood > brain > muscle. Perfluoroalkylsulfonates (PFSAs) were thepredominant compounds accounting for 58−75% of the totalconcentrations, followed by perfluoroalkyl carboxylates (PFCAs;21−35%). 8:2 fluorotelomer sulfonate (8:2 FTS), 10:2 FTS, and 6:2 chlorinated polyfluoroalkyl ether sulfonate were frequentlyfound in the liver (50−90%) and bile (96−100%), whereas hexafluoropropylene oxide dimer acid (HFPO-DA) was rarely found.The hepatic concentrations of ΣAll in river otters collected downstream of a fluoropolymer production facility located along theOhio River were 2-fold higher than those in other watersheds. The median whole body burden of ΣAll was calculated to be 1580μg. PFOS and perfluorooctanoic acid (PFOA) concentrations in whole blood of some river otters exceeded the human toxicityreference values, which warrant further studies.

    Variability in chemistry of surface and soil waters of an evapotranspiration-dominated flood-pulsed wetland: solute processing in the Okavango Delta, Botswana2017Inngår i: Water SA, ISSN 0378-4738, Vol. 43, nr 1, s. 104-115Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Water chemistry is important for the maintenance of wetland structure and function. Interpreting ecological patterns in a wetland system therefore requires an in-depth understanding of the water chemistry of that system. We investigated the spatial distribution of chemical solutes both in soil pore water and surface water, along island-floodplain-channel hydrological gradients in seasonally and permanently inundated habitats between major regions in the Okavango Delta, Botswana. Our results show that major cations (Ca, Na, Mg, and K), dissolved silica (DSi), dissolved boron (B), dissolved organic matter (DOC) and electrical conductivity increased significantly, at  < 0.05, from the inlet of the Delta (the Panhandle) to the distal downstream reaches, suggesting the influence of evapoconcentration. Concentrations of dissolved Fe, Al, Zn, Cu, and Mn significantly decreased, at < 0.05, from the inflow of the Delta to the distal reaches. Only Na, Mn, Fe, Al, and DOC showed significant differences, at < 0.05, along the local floodplain-channel hydrological gradients, with higher solute concentrations in the floodplains than the channels. Solute concentrations in soil water exhibited similar distribution patterns to those in surface water, but concentrations were higher in soil water. Based on the results, we hypothesise that floodplain emergent vegetation and the channel-fringing vegetation in the Panhandle (a fault-bounded entry trough to the Delta) and the permanently inundated eco-region together influence the cycling of solutes that enter the Delta through uptake.
