Concentration of heavy metals (lead & Cadmium) in soft tissue of ( Echinometra mathaei ) in the Qeshm rocky shore

This survey was conducted in winter 2010, aimed to determine the degree of heavy metal accumulation in soft tissue of sea urchin, and determining this tissue as the most suitable bioindicator for lead and cadmium in the environment of the sampling stations. The way of doing this assessment was MOOPAM. Samples were prepared and classified according to sea urchin organ and then lead and cadmium were measured in them. Result of this study shows that soft tissue is a good index for lead and cadmium pollution. The result of bioaccumulation of lead and cadmium in the Soft tissue was 21.4 ±4.5 and 8.6 ± 1.7 mgKg-1. The results showed that in the stations was not significantly different between Heavy metal pollution in soft tissue of sea urchin.
