Heptachlor is an organochlorine cyclodiene insecticide isolated from technical chlordane. It is available in the form of white crystals or a tan-colored waxy solid with a characteris- tic camphor-like or cedar-like odor. It is sparingly soluble or insoluble in water, but fairly soluble in acetone, benzene, ethanol, xylene, and other organic solvents. It is used for the control of termites, ants, and soil insects in cultivated and non-cultivated soils. Heptachlor epoxide is formed in nature when heptachlor is released into the environment and mixes with oxygen. Heptachlor epoxide remains in the soil for long periods of time. Heptachlor and heptachlor epoxide may also be present at numerous hazardous waste sites. Although the use of heptachlor is restricted, exposure to the general population does occur through the ingestion of contaminated food.

개요Heptachlor is a soft, white to light tan, waxy, non-combustible, crystalline solid with a camphor-like odour. Heptachlor is a member of the cyclodiene group of chlorinated insecticides (aldrin, dieldrin, endrin, chlordane, heptachlor, and endosulfan) and has a long history following World War II. It was registered as a commercial pesticide in 1952 for foliar, soil, and structure applications and for malarial control programmes; after 1960, it was used primarily in soil applications against agricultural pests and to a lesser extent against termites. Heptachlor is available commercially as a dust, a dust concentrate, an emulsifiable concentrate, a wettable powder, or in oil solutions. It is corrosive to metals and reacts with iron and rust to form hydrogen chloride gas. Heptachlor is incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides but is stable under normal temperatures and pressures. It may burn, but does not ignite readily. Heptachlor at high heat and temperature produces highly toxic, corrosive fumes of hydrogen chlorine gas and toxic oxides of carbon. An important metabolite of heptachlor is heptachlor epoxide which is an oxidation product formed from heptachlor by many plant and animal species. Heptachlor is almost insoluble in water but soluble in ether, acetone, benzene, and many other organic solvents.

용도Heptachlor is used for the control of termites, ants, household insects and soil insects. It is also applied as a seed treatment, soil treatment or directly to foliage.

일반 설명HEPTACHLOR is a white to light tan waxy looking solid. Noncombustible. Insoluble in water. Can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. Used as an insecticide.
