摘要：In the present study, the Mediterranean mussel Mytilus galloprovincialis, the veined Rapa whelk Rapana venosa and the warty crab Eriphia verrucosa collected from the Black Sea coast of Turkey in order to obtain data on the bioavailability of Al, As, Cu, Zn, Hg, Fe, Cd and Pb in Sinop coast of the Black Sea in 2013. Aims of the study are to investigate the levels of heavy metals in benthic macroorganisms, to compare the results with the maximum permissible limits of these heavy metals proposed by Ministry of Agriculture, Fisheries and Food, European Union, World Health Organization and Turkish Food Codex. Hg showed the least concentrations in all organisms, even was not detected in both M. galloprovincialis and R. venosa. Pb was also not detected in organisms except in M. galloprovincialis. The highest values of Cu, Zn and Fe were determined in E. verrucosa. Al was limit of detection in R. venosa but was measured in E. verrucosa (1.4 µg g-1 dry wt.) and M. galloprovincialis (1.4 µg g-1 dry wt.). As, Cu, Zn, Fe and Cd levels in macrobenthic organisms ranged from 2.3 µg g-1 dry wt. in M. galloprovincialis to 6.7 µg g-1 dry wt. in R. venosa, 0.8 µg g-1 dry wt. in M. galloprovincialis to 53.9 µg g-1 dry wt. in E. verrucosa, 21.6 µg g-1 dry wt. in R. venosa to 54.8 µg g-1 dry wt. in E. verrucosa, 29.3 µg g-1 dry wt. in M. galloprovincialis to 86.5 µg g-1 dry wt. in E. verrucosa and 0.32 µg g-1 dry wt. in E. verrucosa to 4.4 µg g-1 dry wt. in R. venosa, respectively. The weekly intakes of the studied metals per kg of body values not exceeded the Provisional Tolerable Weekly Intake established exception of highest Cd level in R. venosa. The obtained data with guidelines showed that the metals concentration in M. galloprovincialis, R. venosa and E. verrucosa are below the permissible level defined by international organizations with no present any danger to human consumption. These species could be a very good biomonitor for the heavy metals.
