dcterms:description
Assessment of contamination levels of the water ecosystem with polychlorinated biphenyls was evaluated in different fish samples (muscle, skin, viscera) from the Brno water reservoir. There were examined 24 fish, of which 8 predatory (species: Aspius aspius - asp, Perca fluviatilis - european perch, Sander lucioperca - pike perch) and 16 omnivorous (species: Abramis bjoerkna - silver bream, Rutilus rutilus - common roach, Carassius carassius - crucian carp, Abramis brama - common bream, Tinca tinca - tench), altogether. Because PCBs well accumulate in fats, the fat percentage must be extracted from each sample first. We conduct our analysis using the High Resolution Gas Chromatography (HRGC) on two different columns connected in parallel to one injection port with two mý-ECD detectors at their ends. Real samples of fish tissues were analyzed using this system. We focused our attention on PCB indicator congeners no. 28, 52, 101, 118, 138, 153 and 180, and the sum of PCBs. Measured values were compared with the legislation; there were compared differences between PCB concentrations in samples of predatory and omnivorous fish, as well as differences in the distribution of individual PCB congeners into different fish tissues. Samples of water and sediment taken from the reservoir were examined together with samples of fish tissues.
