Abstract: | The concentrations of sixteen compound of organochlorine pesticide (OCPs) were measured in the surface sediment and Crassostrea sp. collected from the aquaculture cage-culture area of the Setiu lagoon. The sampling was done two times in August 2007 during dry-season (Pre-monsoon) and beginning of the rainy season (monsoon) at November 2007. Sediment and oyster, samples were extracted using solid-liquid technique and pesticides determination using gas chromatography with electron capture detector (GC-ECD). The concentration of OCPs in the sediment during first Sruf1pling :md second sampling were ranged 0.003-39.71 ng g- 1 and 0.27-192.74 ng g- 1 respectively. Meanwhile, for the Crassostrea sp. the total range concentration during first sampling was 0.03-434.33 ng g- 1 and for the second sampling was 0.001-28.80 ng g- 1 respectively. The OCPs compound fall into three major group mainly BHC, Cyclodiene and DDT. Each g.0up i.iad a different concentration for every station. The concentration of Cyclodiene group was higher compare to other groups. The concentration of OCPs was significant in the sediment between the dry-season and beginning at the rainy season (Anova (p<0.05)). As a conclusion, the concentration of OCPs in sediments and Crassostrea sp. for the both sampling was in the lowest concentration and not polluted. |
