Danish Environmental Protection Agency evaluation
In oxygen-rich conditions in the soil, the persistence of lindane is not acceptable, with half-lives ranging from 42 to 980 days. In deoxidized conditions half-lives are assessed to be 37 days. Since lindane is not mobile, it will normally occur in the oxygen-rich upper soil layers.

Lindane evaporates easily and thus spreads to non-agricultural areas. Moreover, lindane may easily accumulate in living animals. Lindane is very toxic to birds, and risk assessments indicate that it may be dangerous for birds to swallow dressed rape seed. Lindane is also very toxic to aquatic organisms.
