title: Biodegradation of alpha and beta isomers of endosulphan and endosulphan sulphate in Indian soils.
abstract: The degradation of alpha and beta isomers of endosulphan and endosulphan sulphate in four sterilized and non sterilized Indian soils under laboratory conditions was studied. Degradation was found to be more in non-sterilized as compared to the sterilized soil. The half life of alpha-endosulphan, beta-endosulphan and endosulphan sulphate was found to be 136.8, 273 and 301 days in sterilized Alfisol and 55, 256 and 277 days in non-sterilized Alfisol,respectively. Alpha-endosulphan degraded more readily than beta-endosulphan and endosulphan sulphate under both sterilized and non-sterilized soil conditions.
