| dc.description.abstract | This research was done in order to determine the effect of endosulfan biaccumulation on the growth of carp (Cyprinus carpio). This research was conducted in 40 l of glass aquaria, the initial weight of carp was 0.810.098 g/fish, and the pesticide endosulfan with active ingredient of 350 g/l was used as test solution. Preliminary research was conducted with bioassay test to assess LC50-96h of endosulfan for carp, and then the fish were exposed to some series of exposure concentration, those are 10; 30; and 50% of LC50-96h value or 0.24; 0.72; and 1.2 g/l for 12 weeks. Endosulfan residue analysis in the water and the body of the fish was conducted after: 0, 4, 12, 24, 48, 96, 144, 192, 264 of exposure hours by using liquid gas chromatography (LGC). Body weight of fish was measured weekly. This study resulted that endosulfan was very toxic to the carp with LC50-96h value was 2.42 (2.206-2.652) g/l. Endosulfan bioaccumulation of exposure concentration of 0.24; 0.72; and 1.20 g/l were 67.93; 119.21; and 141.19 g/kg respectively. Bioaccumulation of 119,21g/kg significantly inhibit the growth of carp. | en |
