Contaminants in herring gull eggs from the Great Lakes / authors: Christine Bishop and D.V. Weseloh. : En1-12/90-2E-PDF
"This fact sheet describes changes in the levels of four organochlorine chemicals (see boxon page 8) in Herring Gull eggs between 1971 and 1989 and the biological effects these chemicals have had on waterbirds. Two of the substances that are reported on here originally entered the environment as organochlorine pesticides: dieldrin and dichlorodiphenyldichloroethylene (DDE), which is a breakdown product of the pesticide dichlorodiphenyltrichloroethane 4 (DDT). The other two chemicals are polychlorinated biphenyls (PCBS) and a dioxin known as 2,3,7,8-tetrachlorodibenzo—p-dioxin (2378-TCDD). The fact sheet also explains the reasons for this ongoing study and how the results relate to the Great Lakes environment of which humans are a part"--Page [1].
