The Distribution of Organochlorine Pesticides in the Manir Paddy Agricultural Area
A study on the distribution of chlorinated pesticides in the Manir paddy agricultural area was carried out involving 7 stations. Concentrations of chlorinated pesticide detected in this study were low ranging from 3.64 ng/g – 17.32 ng/g in sediment and 6.17 ng/g – 68.04 ng/g in fish samples. In sediment, the concentrations of DDT group was ranging from 0.39 ng/g – 11.99 ng/g; 0.21 ng/g – 1.43 ng/g for BHC group and 1.22 ng/g – 6.23 ng/g for cyclodiene group. In fish samples, the concentrations of DDT group was ranging from 2.49 ng/g – 6.80 ng/g; 1.58 ng/g – 8.84 ng/g for BHC group and 6.17 ng/g – 52.40 ng/g for cyclodiene group. In this study, the relationship between the chlorinated pesticide concentrations and those of lipids concentrations showed significant relation in the biota but not in the sediment. Relationship between chlorinated pesticides concentrations and total organic carbon, particle sizes and physical parameters of water such as temperature, pH and dissolved oxygen showed no significant difference. Generally, pollution due to chlorinated pesticides in the study area was still low.
