Purpose for use; Organochlorine insecticide.
Mode of action; It is a GABA-gated chloride channel antagonists, acting as a central nervous system stimulant and also an inducer of DNA fragmentation. (ref. ID; 6754)
Toxicity; LD50 (oral): rat (male) 88 mg/kg, (female) 91 mg/kg
According to Austrian standards, lindane belongs to toxicity class 3, "moderately toxic to warm-blooded organisms". It acts as inhalation, ingestion, or contact poison. The LD50 in rats (oral) amounts to 88-225 mg kg-1 and (dermal) 500 mg kg-1 body weight. Lindane is rather persistent. In the laboratory, 50% degradation occurs within 600 days (Laskowski et al. 1983) (ref. ID; 6768)
