Abstract
In India, almost all organochlorine pesticides (OCPs) have been banned but some
farmers and industries are still using it for agricultural purpose. The present
study has been performed for determination of the range of different types of organochlorine
pesticides in the water and sediments samples of Kadinamkulam estuary, South India.
For the analysis, water and sediment samples were collected from the six selected
stations including five coir retting zones and non-coir retting area of the estuary.
Water samples were extracted and analyzed for the determination of pesticide residues
(α, γ and δ BHC, Aldrin, DDT, DDE, Hepatochlor, Endosulphan) using Gas chromatograph
with an ECD detector. The study reveals that the concentrations of all pesticides
studied in sediment samples and in water samples are above the guideline values
for drinking water quality.
