Environmental behaviour of short-chain chlorinated paraffins in aquatic and terrestrial ecosystems of Ny-Alesund and London Island, Svalbard, in the Arctic
The environmental behaviour of short-chain chlorinated paraffins (SCCPs) was investigated in both aquatic and terrestrial ecosystems in the Arctic. The mean concentrations of SCCPs in the aquatic and terrestrial samples were 178.9 ng/g dry weight (dw) and 1572 ng/g dw, respectively. Short carbon cha...
