title: Organochlorine pesticide and polychlorinated biphenyls levels in fish and mussel in Van region, Turkey.
abstract: Forty-seven fish (24 endemic Alburnus tarichi, Güldenstädt, 1814; 8 Capoeta capoeta, Guldenstaedt, 1772; 15 mirror carp Cyprinus carpio, L., 1758) and 13 mussel (Unio stevenianus, Krynicki, 1837) samples, with 10 specimens per sample, were collected from Van Lake, Turkey, and rivers flowing into it. Gamma-HCH was detected in 21 Alburnus tarichi samples (56.57 ng/g ± 22.18 ng/g) and in two Capoeta capoeta samples (27.6 ng/g and 36.45 ng/g). Beta-HCH was detected in 8 Alburnus tarichi samples (24.95 ng/g ± 4.42 ng/g) and in two mussel samples (101.25 ng/g and 129.44 ng/g). HCB was found in one Alburnus tarichi sample (14.4 ng/g) and one mussel sample (181.25 ng/g). The compound 4,4'-DDE was detected in 21 Alburnus tarichi samples (87.13 ng/g ± 32.23 ng/g), in 9 mirror carp samples (304.82 ng/g ± 100.76 ng/g) and one mussel sample (149.31 ng/g). PCB 28 was detected in one Alburnus tarichi (19.46 ng/g) sample and PCB 101 was found in one Capoeta capoeta (60.16 ng/g) sample. PCB 118 was detected in one mirror carp sample (277.5 ng/g) and in two Capoeta capoeta samples (43.77 and 54.38 ng/g). PCB 128 was detected in only one Capoeta capoeta sample (141.48 ng/g). It is concluded that (i) efforts should be made to reduce contamination of aquatic environments by these compounds and that (ii) their levels in fishery products from Van Lake and connected streams should be monitored and publicly reported on a regular basis.
