Biomonitoring of Hg, Pb, Cd and Al metals by use of barnacle in Imam Khomeini Port

Imam khomeini's port is located in the north west end of Persian Gulf with Khor-e-Musa's canal. shipping, vessels accidents and inland industrial pollution can contaminate are pollutive featurewhich affected the reagion, Heavy metals pollutions are so important, Among these factors. Heavymetals are stable pollutant and they aren,t disintegratable with biological activities[1], and also thatthey can accumulat in aquatic creatures. Bivalves are the most important to use as environmentalmonitoring as pollution indicators[2]. Materials and methods:To survey of mercury, copper and plumb's concentrations in Imam Khomeini's port(Fig. 1) and toestimate their accumulation in crassostrea gigas (Bivalve) and also using possibility of this speciesas a heavy metal pollution bio marker, collected the sediment from intertidal regions of Imam Khomeini port on February and July of 2009.Analyzed the samples were doing with mercuryanalyzer (Zeeman Mercury Analyzer RA-915+). Plumbs and copper were analyzed with ICP-AES,ICP-6000 series, belong to Thermo Company made in British. Results Results showed that the average concentrations of mercury, copper and plumbs in sediments are1.30±0.77, 13.28±2.71 and 6.94±1.55 μg/g dry weight alternately. The average of concentrations of mercury, Copper and plumb in soft tissues of bivalves were 5.52±3.04, 662.01±51 and 11.90±4.46 μg/g of dry weight alternately.
