Abstract: Concentrations of organochlorine pesticides (OCPs) m tissue of oyster (Crassostrea irradalei) and sediment in the Merchang river, Marang were determined. The distribution of OCPs in the Merchang river involved 7 sampling stations for the sediment sample s while 6 (1 t sampling) and 3 station (2 °d sampling) for the oyster sample. Oyster, filter feeder and sedentary organisms, were use in order to test OCPs pollution. OCPs compound were widely distributed in Merchang river environment, with BHC, cyclodiene and DDT group contamination being particularly prevalent. The results showed that OCPs widely existed in the sediment sample compared to the oysters sample. st During the 1 sampling in sediment, concentration of :EBHC ranged from 3.67-136.78 ng/g, followed by :Ecyclodiene from 5.78-42.52 ng/g and :EDDT was ranged from 5.32- 35.71 ng/g. Meanwhile, in the oysters sample concentration of :EBHC varied from 0.034- 3.31 ng/g, :Ecyclodienes varied from 0.17-83.93 ng/g and :EDDT from 5.52-8.69 ng/g. However, during the 2" d sampling there were only three stations that was detected in the oyster, with the range of:EBHC from 4.76-31.72 ng/g, �cyclodiene between 26.37-82.89
