Determination of organochlorine pesticides in Indian coastal water using a moored in situ sampler
Abstract
Residues if various organochlorine pesticides were determined in the water off the central west coast of India using an in situ sampler. Y-BHC and the two cyclodiene compounds, Aldrine and Dieldrin were found to be more consistent than the compounds of the DDT family. Y-BHC ranged from 0.26 to 9.4 ng1-1 whereas Aldrin and Diedrin were from 1.4 to 9.8 and k2.1 to 50.9 ng1-1, respectively. Among the compounds of the DDT family, Pp-DDT was found to be more abundant than the others in the southern part of the region, whereas Op-DDt was present in a fairly considerable amount off Ratnagiri coast. Among the metabolities of DDT, Pp'-DDE was found to be present in every alternate station with increasing concentration (2.5-20.39 ng1-1) whereas Op'-DDE could be detected occasionally in the northern part of the region. Presence of Op'-DDD was observed only in one sample off the Ratnagiri coast, whereas Pp'-DDD was not detected at all.
