- Chlorinated paraffins (CPs) were analyzed in marine wildlife from Greenland, Iceland, and the Swedish west coast. CPs up to C29 were detected in the samples from the Arctic, indicating long-range transport of an industrial chemical group with a 2-million-ton annual production volume. CP concentrations were generally higher in biota from the Swedish west coast. The Sweden/Arctic concentration ratios for very-short-chain (vSCCPs, C<10), short-chain (SCCPs, C10-13), medium-chain (MCCPs, C14-17), and long-chain CPs (LCCPs, C>17) in cetacean and bivalve species were in the range of 3.6-150, 5-29, 3-11, and 11-450, respectively. For the first time, fetal accumulation of four CP classes was found, whereby concentrations were 3.4 to 4.5 times lower in the fetus relative to the pregnant female minke whale. Cetacean blubber contained a higher proportion of higher chlorinated CPs compared to muscle tissue, while muscle contained higher lipid-normalized concentrations of longer chain CPs than blubber tissue. LCCPs predominated (52% of total CPs) in the muscle of a killer whale from Swedish waters, which is the first report where concentrations of LCCPs surpassed those of other CPs in marine mammals. This study shows that, like other CP classes, LCCPs are Arctic contaminants that may adversely affect biota in this remote region. © 2021 The Authors.
