Bioaccumulation and effects of parent and alkylated PAHs in an Arctic marine amphipod (Gammarus setosus) originating from pristine and historically contaminated sites in Svalbard. Implications for sensitivity and adaptation
The objectives of the study were to assess the bioaccumulation and genotoxic effects of PAHs and their alkylated PAHs from marine diesel fuel and coal polluted sediments in two populations of Gammarus setosus. Testing whether the alkylated forms are bioaccumulating more than their parent compounds,...
