Abstract

According to various pollution sources, have adverse effects on the health of ecosystems in a region, It is important to estimate the amount of contamination in the area. In this study, Concentrations of Ni, Cd and Pb in the soft tissues of the bivalve Saccostrea cucullata were examined at 4 ages categories and 3 longth categories in beaches Loft Port by ICP-OES.
The results showed that the mean concentrations of Ni, Cd and Pb were in the 4 age categories Respectively: Nickel (78.55, 36.77, 34.65 and 25.61), cadmium (5.73, 4.55, 5.70 and 5.03), lead (21.74, 9.53, 8.26 and 8.10) micrograms per gram dry weight and The results showed that the mean concentrations of Ni, Cd and Pb were in the 3 longth group Respectively: Nickel (74.68, 35.61, 30.67), cadmium (5.65, 5.36, 4.76), lead (18.65, 9.52, 9.19) micrograms per gram dry weight that Lead and cadmium levels in 3 length categories and 4 age categorieswere higher than the standard limit EPA and FDA but The nickel content in 3 length categories and 4 age categories are less than standard. Since Saccostrea cucllata is oyster, Eating it in any size can be dangerous to humans and other creatures of the consumer
