Monitoring heavy metals pollution in Bandar Emam region by using atomic absorption technique

The level and distribution of five heavy metals Ni, V, Cr, Pb, and Cd in the sediments waters of three areas Bandar Emam were investigated by the use of atomic absorption technique. Metals have been analyzed for different grain size fractions. These metals levels in sediment are expressed as μgg4+ and metal level in water is expressed as ppm. The concentrations of the elements under investigation is much higher than the concentrations of these elements and these of mean in sediments and waters which were compared with the concentration of these elements in the earth crust and international atomic energy agency and ICRP standards. Significant variations in the level of these metals were considered due to: atmospheric fall out as well as waste waters disposal and anthropogenic inputs, Ni and V were due to non-anthropogenic sources and analysis indicate that the sources of Cr and Cd are mainly oil pollution. High level of lead was considered due to inputs from oil discarded solid waters and the prior high rate petrol combustion lead. Monitoring water and sediments, in other words periodic or continuous determination of the amounts of ionizing radiation in water and sediments is one of the positive steps against the pollution in these regions
