摘要：The purpose of this study was to determine the type and concentration of organochlorinepesticides contained in sea water and sediments in the waters of Manado Bay. Sampling was carried outat three stations, namely Station 1 - in front of Malalayang Terminal, Station 2 - Megamas, Station 3 -Tumumpa. Samples were analized using the Gas Chromatography Mass Spectrometry method. Theresults of the analysis found that the type of organochlorine pollutants was the aldrin type in which thehighest concentration was found in the substrate at the Megamas location at 1.020 ppm then followed bythe substrate at the Tumumpa location at 0.049 ppm and finally the substrate at the Malalayang locationat 0.49 ppm. The concentrations in seawater samples were at Tumumpa 0.925 ppm, then followed by0.899 ppm at the Megamas location and finally at Malalayang location 0.792 ppm. The aldrinconcentration for the substrate found at Megamas station and for the water samples found at Tumumpalocation had passed the allowable quality limit (0.0624 ppm).
