BHC-Gamma, also called Lindane, is a banned pesticide that can enter water from agricultural runoff. It causes nervous system and liver damage when ingested.

BHC-Gamma, an organochlorine pesticide, persists in the environment long after its use was banned. It can contaminate water through soil erosion and agricultural runoff. This chemical bioaccumulates in the food chain, posing risks to wildlife and humans. Detected using gas chromatography, BHC-Gamma is regulated globally under the Stockholm Convention. Also known as gamma-hexachlorocyclohexane or gamma-HCH, it exemplifies the long-term consequences of past pesticide use on water quality.
