Temporal Trends and Age-Dependent Sex Differences in Chlorinated Paraffin Accumulation in Moose
Previous studies have found relatively high chlorinated paraffin (CP) concentrations in moose (Alces alces) compared with other wildlife from Scandinavia. To explore CP accumulation behaviors in this long-lived terrestrial mammal, temporal trends of muscle concentrations of CPs were first measured i...

Previous studies have found relatively high chlorinated paraffin (CP) concentrations in moose (Alces alces) compared with other wildlife from Scandinavia. To explore CP accumulation behaviors in this long-lived terrestrial mammal, temporal trends of muscle concentrations of CPs were first measured in samples collected over the past 40 years from moose calves from Grimsö, Sweden. The four CP classes, i.e., very-short-chain, short-chain, medium-chain, and long-chain (LCCPs) classes, showed similar temporal trends, with increasing concentrations from 1982 to the 1990s, relatively high levels in two time periods around 1993 and 2008, and decreasing concentrations after 2012.
