Comparison of organochlorine contaminants among sea otter ( Enhydra lutris) populations in California and Alaska
Abstract Organochlorine pesticides, polychlorinated biphenyls (PCBs) including non‐ ortho PCBs, polychlorinated dibenzo‐ p ‐dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) were measured in sea otter liver tissue from California, southeast Alaska, and the western Aleutian archipelago colle...
