Organochlorine contaminant concentrations in double-crested cormorant eggs or nestlings in the Green Bay, WI region from 1994 and 1995
Double-crested cormorant (Phalacrocorax auritus) fresh eggs and sibling embryos at pipping were collected from a polychlorinated biphenyl (PCB)- contaminated colony in Green Bay, Wisconsin, USA. Egg contents were analyzed for organochlorine (OC) contaminants, including 15 aryl hydrocarbon-active PCB congeners. Concentrations of 20 organochlorine contaminants present in double-crested cormorant eggs and nestlings from the upper Midwest, including the Green Bay system, are presented in this data report and include alpha-, beta-, gamma- and delta-hexachlorocyclohexane (HCH); alpha- and gamma-chlordane; oxychlordane; cis-nonachlor; trans-nonachlor; dieldrin; endrin; hexachlorobenzene (HCB); heptachlor epoxide; mirex; toxaphene; o,p-dichlorodiphenyldichloroethane(DDD); o,p-dichlorodiphenyldichloroethylene (DDE); o,p-dichlorodiphenyltrichloroethane (DDT); p,p-DDD; p,p-DDE; p,p-DDT; and total PCBs. Total PCBs were estimated based on Aroclor equivalents. See Environmental Toxicology and chemistry publications noted elsewhere for additional information. QA/QC were approved by the Patuxent Analytical Control Facility, Laurel, MD.
