Meaning and Definition
A toxic organochlorine chemical compound with the formula C6H6Cl6, historically used as an insecticide.
A synthetic chemical, specifically an isomer of hexachlorocyclohexane, known for its insecticidal properties. Its gamma isomer, called Lindane, was widely used in agriculture and pharmaceuticals before being banned or restricted due to its persistence, toxicity, and environmental accumulation.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both varieties use the same term. The name 'Lindane' for the gamma isomer is standard internationally.
Connotations
Both carry strong connotations of toxicity, environmental harm, and historical agricultural use.
Frequency
Equally low frequency in both varieties, confined to technical fields and historical discussions of pesticides.

FAQ
Frequently Asked Questions
Lindane is specifically the gamma isomer of benzene hexachloride (BHC), which was the isomer with the most potent insecticidal activity. 'Benzene hexachloride' often refers to the technical mixture of isomers.
It is a classic example of a persistent organic pollutant (POP). Its rise and fall as a pesticide highlight the unintended consequences of persistent chemicals on ecosystems and human health, shaping modern environmental regulations.
Its agricultural use is banned globally under the Stockholm Convention due to its toxicity and persistence. Very restricted pharmaceutical use of Lindane (e.g., for scabies) has also been phased out in most countries.
Yes. It is neurotoxic, can damage the liver and kidneys, is a suspected carcinogen, and can disrupt the endocrine system. Exposure typically occurs through contaminated food, water, or soil from historical use.
