Is chlordane harmful to humans?
Exposure to chlordane occurs from its past use as a pesticide. The acute (short-term) effects of chlordane in humans consist of gastrointestinal distress and neurological symptoms, such as tremors and convulsions. Chronic (long-term) inhalation exposure of humans to chlordane results in effects on the nervous system.
What countries still use chlordane?
Because of their persistence and high propensity for bioaccumulation, most cyclodienes have been banned in most developed countries. Some of the cyclodienes such as chlordane and endosulfan continue to be widely used in China, India, and parts of Africa.
Is chlordane safe for humans?
Chlordane is a moderately toxic systemic poison that is absorbed well by inhalation, and through the skin. It is also irritating to the skin and eyes on direct contact. Rescuers should wear chlordane-resistant gear.
