Organochlorine pesticide and PCB contents in otter (Lutra lutra) scats from western Scotland

摘要: Organochlorine pesticide residues and PCBs were measured in 113 otter (Lutra lutra) scat samples from 94 sites the River Clyde catchment, its estuary neighboring coastal waters western Scotland. Contents of generally low. PCB amounts high some regions study area (geometric mean contents up to 19.5 mg kg−1 lipid). Potential sources contamination included industrial areas, a sewage sludge dump shipping facilities, both naval commercial. tissues estimated scats. Analysis scats provides useful technique estimating potential threats populations can be used identify biologically significant hot-spots which may missed by more familiar surveillance methods.
