Polychlorinated Biphenyls in Freshwater Fish from the Zagreb Area
Puni tekst: pdf (85 KB),
Str. 303 - 309
The aim of this study was to determine the levels of six polychlorinated biphenyls (referred to as PCB-28, PCB-52, PCB-101, PCB-138, PCB-153 and PCB-180, according to the IUPAC) in freshwater fish from the Zagreb area. A total of 216 samples was collected from five sites: from the Sava River upstream of Zagreb, in Zagreb, and downstream of Zagreb, from Lake Jarun, and from five fishponds from the Zagreb surroundings. Samples from all five sites contained polychlorinated biphenyls (PCBs). The maximal levels
found in individual samples ranged between 20 μg kg-1 and 50 μg kg-1 depending on the congener. However, the total level of all examined congeners was far below the maximal allowed level of 2.0 mg kg-1 ww, set by Croatian authorities for total PCBs.
