(Also known as: toxaphene; polychlorocamphene; chlorocamphene; toxafeen; octachlorocamphene)
SUMMARY
Camphechlor is an obsolete insecticide and acaricide that is not approved for use in the EU. It has a low aqueous solubility, is quite volatile and moderately mobile. Based on its chemical properties, it has a high risk of leaching to groundwater. It is not expected to be persistent in soil but may be persistent in water systems. Camphechlor is highly toxic to mammals and is likely to bioaccumulate. It is highly toxic to birds and most aquatic organisms.
