متن کاملChlordane and Heptachlor
Chlordane and heptachlor were considered together because of their close structural similarity and because technical-grade products each contain about 10–20% of the other compound. These substances were considered by previous working groups, in 1978 (IARC, 1979), 1987 (IARC, 1987) and 1990 (IARC, 1991). Since that time, new data have become available, and these have been incorporated into the m...
متن کامل2. Relevance to Public Health 2.1 Background and Environmental Exposures to Heptachlor and Heptachlor Epoxide in the United States
Heptachlor is a polychlorinated cyclodiene insecticide that was extensively used prior to 1970 to kill termites, ants, and soil insects in seed grains and on crops. In 1983, the manufacturers voluntarily cancelled its registered uses, with the exception of termite and fire ant control. Currently, the only permitted use of heptachlor is for fire ant control in buried power transformers; however,...
متن کاملMetabolism of organochlorine pesticide heptachlor and its metabolite heptachlor epoxide by white rot fungi, belonging to genus Phlebia.
White rot fungi of the genus Phlebia have demonstrated a high capacity to degrade organic pollutants, including polychlorinated dibenzo-p-dioxins and polychlorinated biphenyls. In this study, we evaluated the ability of 18 white rot fungi species of genus Phlebia to degrade heptachlor and heptachlor epoxide, and described the metabolic pathways by selected white rot fungi. Phlebia tremellosa, P...
متن کاملBioassay of heptachlor for possible carcinogenicity.
A bioassay of technical-grade heptachlor for possible carcinogenicity was conducted by administering the test material in feed to Osborne-Mendel rats and B6C3F1 mice. Groups of 50 rats of each sex were administered low or high concentrations of the heptachlor for 80 weeks, then observed for 30 weeks. Doses for females were first increased, but because of toxic effects the doses were then reduce...
