“…55.9 ng g −1 ; range: 13.6–155 ng g −1 ). The higher concentrations in the coastal and southern populations are likely associated with diet (coastal/marine-based diets can be expected to contain higher levels of PFAS compared to inland/terrestrial), and proximity to more densely populated areas in Sweden (as seen for surface water and fish 46,47 ), and can also be attributed to the sedentary nature of the territorial adults. 48…”

“…A decrease in the BAF with chain lengths >C 11 has been linked to steric hindrance for longer chain length PFCAs, which reduces bioavailability. 40 While BAFs for herring liver PFCAs will be 10−20 times higher than BAFs for muscle, 27 the general pattern for chain length dependence remains the same. For PFSAs, water−herring BAFs increased from PFHxS (log BAF 2.8 ± 0.2 L kg −1 ) to PFOS (4.2 ± 0.3 L kg −1 ).…”

Temporal and spatial variability of per- and polyfluoroalkyl substances (PFASs) in herring, cod, eelpout, and guillemot covering four decades and more than 1000 km in the Baltic Sea was investigated to evaluate the effect of PFAS regulations and residence times of PFASs. Overall, PFAS concentrations responded rapidly to recent regulations but with some notable basin- and homologue-specific variability. The well-ventilated Kattegat and Bothnian Bay showed a faster log-linear decrease for most PFASs than the Baltic Proper, which lacks a significant loss mechanism. PFOS and FOSA, for example, have decreased with 0–7% y–1 in the Baltic Proper and 6–16% y–1 in other basins. PFNA and partly PFOA are exceptions and continue to show stagnant or increasing concentrations. Further, we found that Bothnian Bay herring contained the highest concentrations of >C12 perfluoroalkyl carboxylic acids (PFCAs), likely from rivers with high loads of dissolved organic carbon. In the Kattegat, low PFAS concentrations, but a high FOSA fraction, could be due to influence from the North Sea inflow below the halocline and possibly a local source of FOSA and/or isomer-specific biotransformation. This study represents the most comprehensive spatial and temporal investigation of PFASs in Baltic wildlife while providing new insights into cycling of PFASs within the Baltic Sea ecosystem.

“…Muscle and liver samples are used for the contaminant analysis of fish specimens. The sample tissue is selected based on the distribution of contaminants in the two tissues, and in some cases, to continue historic time-series for a specific tissue in the MCoM 38 . Muscle samples are taken from the middle dorsal muscle layer after the epidermis and subcutaneous fatty tissue have been carefully removed.…”

Widespread persistent contaminants are a global environmental problem. In the Baltic Sea, wildlife contamination was first noticed in the 1960s, prompting the Swedish Environmental Protection Agency to establish a comprehensive Swedish National Monitoring Programme for Contaminants in Marine Biota (MCoM) in 1978 run by the Swedish Museum of Natural History. Eight species have been analysed, four fish species (Atlantic herring, Atlantic cod, European perch, viviparous eelpout), one bivalve species (blue mussel), and egg from three bird species (common guillemot, common tern, Eurasian oystercatcher). Here, we present a dataset containing MCoM data from its start until 2021. It includes 36 sets of time-series, each analysed for more than 100 contaminants. The longest time-series is for common guillemot and starts in 1968. We describe the structure of MCoM including historic changes to the number of stations, sample treatment, analytical methods, instruments, and laboratories. The MCoM data is available at the Bolin Centre repository and on GitHub through our R package mcomDb. The latter will be updated yearly with new MCoM records.
