Abstract | In view of DDT persistence in the aquatic environment, a dynamic biological system capable of simultaneously distinguishing between bioaccumulation and biomagnification through successive trophic levels in an aquatic system was studied at room temperature (30°C). The organisms used in the system were algae, predominantly Chlorella sp., fresh water mussels, Viriparus sp. and the fishes Puntius gonionotus sp · The DDT, because it is not soluble in water, was used in hexane solution in applying to the system. The water and organisms were analyzed weekly for DDT concentrations during the 8-week experimental period. DDT can be bioaccumulated by fish and algae, and magnified also by fish. Fresh water mussels were found to be a poor indicator of DDT contamination. |
