Abstract
The study determined current exposure of tigerfish in Lake Pongolaqpoort to organohalogens. Levels of DDT, PCB, HCB, HCH, PBDE and CHLs were measured in tigerfish muscle on a seasonal basis. Historical use of DDT was reflected in the bioaccumulation patterns (5,400–6,000 ng/g lipid) as well as current use of HCBs (7.7–15.7 ng/g lipid) in the agricultural areas. External factors, i.e. increased flow did not play a role in organic pollutant exposure. Levels are a function of the lipid content of the muscle tissue, i.e. 3.8% during low and 9% during high flow, implying that organohalogen exposure remains fairly constant throughout the year.
