Heavy metal accumulation in a bioindicator species, Limpet Patella caerulea, in Yalova (?zmit Bay): Risk assessment for human health

In this study, monthly heavy metal concentrations in the whole-body tissue of Patella caerulea (Mediterranean limpets), a bioindicator species living coastal zone Gulf Izmit (Marmara Sea), were examined for first time. The mean (mg kg-1 dw) 2.01–5.74 Cd, 2.45–12.90 Cu, 0.74–1.95 Pb, 21.12–109.57 Zn, 16.31–154.67 Ni, and 1120.67–3086.00 Fe. Cd levels all months Pb October November found to be above safe limits set by international organizations. estimated daily intakes weekly determined each below acceptable provisional tolerable intakes. However, target hazard quotient total values calculated Fe higher than 1. carcinogenic risk value was also high.
