PFASs in the Nordic environment

Screening of Poly- and Perfluoroalkyl Substances (PFASs) and Extractable Organic Fluorine (EOF) in the Nordic Environment

This report describes a screening study of in all ninety-nine conventional and emerging per- and polyfluoroalkyl substances (PFASs) in the Nordic environment. In addition, extractable organic fluorine (EOF) was analysed. The latter can provide the amount, but not identity, of organofluorine in the samples, which in turn can be used to assess the mass balance between known and unknown PFASs. The study was initiated by the Nordic Screening Group and funded by these and the Nordic Council of Ministers through the Chemicals Group.A total of 102 samples were analyzed in this study, including bird eggs, fish, marine mammals, terrestrial mammals, surface water, WWTP effluents and sludge, and air. Samples were collected by institutes from the participating countries and self-governing areas; Denmark, Faroe Islands, Finland, Greenland, Iceland, Norway, and Sweden.



Frame of the study

Environmental screening studies can provide early identification of potential harmful substances. Screening studies are important to identify the need of further environmental monitoring. With a screening approach it is possible to consider environmental issues on an early stage and such studies should be considered as a first step rather than a comprehensive assessment. Results from a screening study can be used to determine the level of details needed of further environmental studies and direct efforts towards potential risks. The outcome of this study will provide recommendations on further monitoring, and hopefully initating processes to reduce or prevent potentially negative environmental impacts on the Nordic environment.
