Trends of Chlorinated Organic Contaminants in Great Lakes Trout and Walleye from 1970 to 1998

by Springer  (Nov. 18, 2005)

Abstract  Levels of chlorinated organic contaminants in predator fish have been monitored annually in each of the Great Lakes since the 1970s. This article updates earlier reports with data from 1991 to 1998 for lake trout (Salvelinus namaycush) and (Lake Erie only) walleye (Sander vitreus) to provide a record that now extends nearly 30 ...

Levels of organochlorine pesticides residues in meat

by International J. of Environmental Science & Tech.  (Sep. 1, 2007)

Abstract: Concentrations of organochlorine pesticides (Lindane, Aldrin, Dieldrin, Endosulfan, DDT and DDE) residues in beef samples from the Kumasi and Buoho abattoirs in Ghana were determined using gas chromatography. Organochlorine residues were found in all the samples. The average concentration of lindane in beef fat samples from Kumasi was ...

How treatment of homes for termites decades ago may cause diabetes today

The initial investigations showed that the expected association between obesity and diabetes/insulin resistance was absent in people who had low levels of ...

Temporal and Spatial Trends in Chlorinated Hydrocarbon Concentrations of Mink in Canadian Lakes Erie and St. Clair

by Springer  (Feb. 1, 2006)

Mink (Mustela vison) carcasses were collected from local commercial trappers from fall 1998 to spring 2003 from tributaries and marshes within 4.8km from the shores of Lakes Erie and St. Clair, including the Wheatley Harbour and St. Clair River Areas of Concern (AOCs), as well as from inland sites (8 to 40km from shore). Liver concentrations, on a ...
