Biodegradation of the Gamma Isomer of Benzene Hexachloride in Submerged Soils

Determination of the residual gamma isomer of benzene hexachloride (ggr-BHC) by gas chromatography showed that the insecticide persisted longer in sterilized flooded soils than in nonsterilized flooded soils. A second addition of ggr-BHC to one of the nonsterilized soils. (55 days after the first application) disappeacgrared more rapidly than the first addition. These results strongly indicate biodegradation of ggr-BHC in flooded soils.
