Organochlorine pollutants in the major fish species (pike Esox lucius, perch Perca fluviatilis, and roach Rutilus rutilus) of Lake Arungen, Norway, were investigated after an extensive removal of large pike in 2004. The organochlorine pollutants detected in fish liver samples
For 15 months in 1981-1982, the commercial milk supply on the Hawaiian island of Oahu was contaminated with heptachlor epoxide, a metabolite of the insecticide heptachlor, resulting in gestational and/or lactational exposure to offspring of women who drank cow milk
The genotoxic potential of the organochlorine insecticides heptachlor (HC) and its metabolite heptachlor epoxide (HCE) has been evaluated in TK6 cells, a well-established human lymphoblastoid cell line. Genotoxicity has been determined by scoring the induction of DNA breaks in the
The effects of the organochlorine (OC) liver tumor promoter heptachlor epoxide (HE; 0, 0.1, 1, 10, and 50 microM) on several cellular tumor promoter-sensitive parameters were studied in mouse 1c1c7 hepatoma cells in an effort to identify the most sensitive
Selected organonitrogen, organophosphorus and organochlorine pesticides have been determined in precipitation samples collected at 10 sites in the Gdańsk region (northern Poland) over a period of one year (1998). Compounds which were detected most often included simazine (0.11-5.80 ng/l), fenitrothion
