Abstract

In this research, the pollution of heavy metals- like copper, lead, cadmium- in southern coast of Caspian Sea (Around Noshahr and Abbas Abad) has been investigated. In this study, environmental factors (Grading scale, organic matter, temperature, salinity, electrical conductivity, pH, dissolved oxygen and density of heavy metals has been assessed. Sampling from seabed sediment using 0.1m2 grab van vein in spring, from 20 station (along 5 transects, each one containing 4 stations), in the depth of 5, 10, 15, 20 metre has been performed. Geographical coordinates by GPS has been recorded. Environmental factors including depth, temperature, dissolved oxygen, salinity, electrical conductivity and pH has been measured using CTD and heavy metals density by atomic absorption. The average temperature of seabed water was 22.19c0, dissolved oxygen was 10.41mg/lit, salinity was 7.05 ppt, electrical conductivity was 18.59 mz/cm, and acidity was 8.41. The average density of cupper in sediment which has been studied was 3.82, cadmium was 1.81, and lead was 14.49mg/kg. Density of heavy metals has been less than intrnational standard levels. The percentage of total organic matter in sampling station has been different and its average was 9.20 percent. Caspian seabed texture in this study is mostly included soft sediment (clay and silt).
