gamma benzene hexachloride

Gamma benzene hexachloride (BHC) refers to stereoisomers of 1,2,3,4,5,6-hexachlorocyclohexane, created by adding chlorine to benzene under light. The gamma isomer, known as lindane, is a potent insecticide, approximately 1,000 times more toxic than other isomers. While effective against insects due to its volatility and rapid action, lindane accumulates in the food chain. Exposure can lead to nervous system dysfunction and may affect liver function in humans. Consequently, its indoor use is banned, and many countries have prohibited its use as an insecticide, though topical applications for lice are still permitted.12
