The present study was aim to determine the concentrations
of copper,
cobalt, lead, zinc, cadmium, manganese, nickel and iron in the edible tissues
of Liocarcinus
depurator (decapoda), Rapana
venosa (gastropoda) and Mytilus
galloprovincilais (mollusca) collected from Samsun coasts of the Black Sea,
Turkey in 2010. These biomonitor species are major food sources of benthic
ecosystem. Exposing to heavy metals at higher concentrations might be toxic to
demersal fish species and also humans. The concentrations of the metals were
carried out using Flame Atomic Absorption Spectrophotometer (UNICAM 929). Metal
concentrations in L. depurator, R. venosa and M. galloprovincilais
decrease in the order: Fe > Zn > Mn > Cu > Ni > Pb > Co >
Cd; Fe > Zn > Cu > Pb > Mn > Cd > Ni and Fe > Zn > Cu
> Pb > Mn > Co > Ni > Cd, respectively. The results showed that
the Fe and Zn concentrations were the highest in edible tissues of the three
benthic organisms, respectively. Mn was higher in the edible tissues of L. depurator than those in other
species, while R. venosa and M. galloprovincilais
shows more of Cu and Pb levels. The estimates of EWI and EDI indicated no
health risk as values are lower than the allowed tolerable levels cited by
internationals committees. Based on the above results of this study, metal
accumulation in the biomonitor demersal species study did not exceed the
permissible limits set for heavy metals by FAO/WHO.
