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.

Thus, for these compounds it seems to be important to calculate species specific ratios. Even though no significant difference in PFOS liver:muscle ratio was found between species, it might not be appropriate to use a mean ratio for all the species, since only some of the species did show a linear relationship between the liver and muscle. For herring and perch (both marine and limnic), there were strong linear relationships between liver and muscle, therefore these can be grouped. The derived EQS NATIONELL MILJÖÖVERVAKNING PÅ UPPDRAG AV NATURVÅRDSVERKET for liver needs to assure the same level of protection as the original EQS. Thereby, the lower limit of the 95% CI for the liver: muscle ratio is used in the calculation of a liver EQS. The existing EQS of 9.1 µg/kg wet weight in edible parts of fish to liver concentrations multiplied with 17.0 (mean ratio liver:muscle =18.4, 95% CI 17.0, 20.4) gives a value of 155 µg/kg wet weight for liver in perch and herring. For the other species more samples are needed in order to be able to recalculate the existing EQS in edible parts of fish to liver concentrations.
