Polychlorinated dibenzo-p-dioxins, dibenzofurans and biphenyls in crucian carp (Carassius auratus) from rivers in Korea during 2000-2004.

Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were analyzed in freshwater fish (crucian carp) taken from 16 locations in nine rivers and a wetland in Korea, during 2000-2004. Dioxin-like polychlorinated biphenyls (DL-PCBs) were also analyzed in the same samples but over shorter period (2002-2004). Concentrations on a wet weight basis for 3 years (2002-2004) ranged from below the detection limit (DL) to 0.
