Lead Concentration in Sediment and Euchelus asper in Rocky Shores of Kish Island

Persian Gulf waters remain heavily impacted by a number of pollutants originating from different sources such as direct and indirect discharge of land based pollutants, sewage etc. Millions of tons of industrial effluents are dumped into the gulf shallow waters every year and the environment is highly contaminated in many urban and industrialized areas of many countries. As a result, high concentrations of heavy metals occur in some areas.The aim of the present study is to determine the bioaccumulation of heavy metals such as lead in water, sediment, soft and hard tissues of Euchelusasper at four selected stations of Kish Island’s rocky shores in winter and summer of 2014. Lead in water samples were assayed (after preparation and chemical digestion) using Perkin Elmer 4100 atomic absorption spectrometer. Lead heavy metal concentrations obtained in four stations in winter and summer, respectively, in soft tissue were 2.57 ppb and 2.02 ppb, in hard tissue 2.28 ppband10,1 ppb, in sediment 2.23 ppb and 1.73 ppb and in water, lower than detection limit.
