Isolation and characterisation of organochlorine pesticides residues from landfill sites.
Organochlorine pesticides (OClPs) have been analysed in the soil samples collected from landfill site, which was abandoned for more than ten years. The most commonly used OClPs of the region were identified and analysed in the soil samples collected at various depths. The method involves extraction of OClPs by soxhlet assembly, concentration cleanup by alumina and florisil columns and gas chromatographic analysis. Among OClPs analysed, g-HCH concentration was found maximum at 5 m layer and minimum at the bottom layer. p,p'-DDT was not found in any of the layers, this could be due to its degradation into its metabolites like p,p'-DDE and p,p'-DDD. p,p'-DDE was detected in 2 m, 5 m and bottom (7 m) layer while p,p'-DDD was found only at 2 m level.
