Summary: Lindane is the gamma isomer of benzene hexachloride. It was formerly used as an active ingredient in pesticides. Current uses in shampoos may be used to eradicate lice. It has low solubility in water and a density of 1.87 g/mL at 20 C. Upon decomposition it will produce hydrogen chloride and phosgene gas. The compound is corrosive to metals. It has a biological half-life of 31.08 days in fish. It is classified by the EPA as a Hazardous Air Pollutant (HAPs). As a vapor in the atmosphere it will be degraded by reaction with hydroxyl radicals with a half-life of 84 days. Koc values ranging from 400 – 2000 indicate low to moderate mobility within soil. Volatilization is expected to occur in soil and water, and along with hydrolysis and biodegradation (under anaerobic conditions) they are expected to be major methods of natural removal. Bioaccumulation is expected to be high. Lindane is expected to be a persistent environmental contaminant.
