Hexachlorocyclohexanes including lindane

Hexachlorocyclohexanes (HCHs; CAS 608-73-1) are a group of manufactured chemicals. HCHs were produced and used as insecticide on fruit, vegetables, and forest crops, and for direct application on animals and animal housing, a few decades ago. It is also available as a prescription medicine to treat or control scabies and head lice in humans. HCHs were recently included as new persistent organic pollutants in the Stockholm Convention. They are not produced anymore in most countries.
