Description
| - In October 1996, in a reservoir with water level at 470.81 m above sea level (flooded area of the reservoir was 345 hectares), 33 fish of 10 species (Esox lucius, Perca fluviatilis, Oncorhynchus mykiss, Salmo trutta m. fario, Leuciscus cephalus, Rutilus rutilus, Abramis brama, Carassius carassius, Tinca tinca, Chondrostoma nasus) were examined to record the starting levels of muscle contamination with metals (Hg, Cd,Pb,Cu,Zn,As,Cr,Al); polychlorinated biphenyls (PCBs) and their indicator congeners 28, 52, 101, 118, 138, 153, 180 and planar congeners 77, 126, 169; pesticides on the basis of 1,1,1-trichloro-2,2-bis(p-chlorphenyl)ethane (DDT) and its metabolites o,p´-DDE, p,p´-DDE, o,p´-DDD, p,p´-DDD, o,p´-DDT, p,p´- DDT; hexachlorcyclohexane (HCH) and its alpha, beta, gamma and delta isomers; and hexachlorobenzene (HCB). The multi-purpose reservoir of non-salmonid type had a drainage area of 464 km2 and its ichthyobiomass represented at least 20 species with prevalence of cyprinids (Rutilus rutilus, Abr
