Assessment of the contaminant concentration variability among Lake Geneva Arctic char using stable isotopic composition (δ 15 N and δ 13 C)
Abstract Measurements of organochlorine [polychlorinated biphenyls (PCBs) and dichlorodiphenyl‐dichloroethylene (DDE)] and Hg concentrations and nitrogen and carbon stable isotopic compositions (δ 15 N and δ 13 C) were performed on 63 Arctic char ( Salvelinus alpinus ) from Lake Geneva. Fish exhibit...
