Lindan (Lindane) is the gamma-isomer of hexachlorcyclohexane (HCH), the insecticidal properties of which were discovered in 1935. It can have toxic effects in humans. In the USA since 1992 it may not legally be contained in drinking water at a strength greater than 0.2 parts per billion. Its manufacture was forbidden in Germany in 1988, and a "Ban Lindane" campaign started in Europe ca. 2000
