Abstract
The fate of ({sup 14}C)-{gamma}-hexachlorocyclohexane ({gamma}-HCH) was studied in green manure amended and unamended flooded soils with a continuous-flow system permitting {sup 14}C mass balance. There was a greater loss of radioactivity in the form of organic volatiles and {sup 14}CO{sub 2} in green manure amended than unamended soil. The organic volatile compound formed was identified as benzene. Green manure amendment considerably decreased the levels of extractable residues from soil. Bound residue formation was also less in green manure amended than unamended soil.
