Description

A pale yellow, oily liquid used as an insecticide. Chlordane was introduced in 1945 for the control of cockroaches. Within ten years, it was the most widely used insecticide in the United States. In 1975, the use of chlordane was restricted to subterranean termites because of its toxicity to humans. It is also an environmental hazard because it is very persistent and does not breakdown with time.
