Today direct and indirect pollution of aquatic ecosystem (rivers, especially estuaries) and consequently pollution of seas is one of the main problems in our environment. In this research, the rate of Cd in Pontogammarus in Anzali coast was monitored and absorption rate of Cd were measured. In this survey, after determining of 5 stations in Anzali coastal, sampling and analyzing of them were done with the standard MOOPAM method, then the concentration of Cd in Pontogammarus of 5 stations was measured and analyzed. In the next stage, alive samples from the cleanest station the zone with the least concentration of Cd in Gammarus body, (Goo Beach) were collected and transferred to aquariums with different concentration of Cd the Laboratory. Then the absorption of Cd in several concentrations of 0.004, 0.006 and 0.008 by Pontogammarus was measured in time periods of 24, 48, 72 and 96 hours. The results of absorption rate of this heavy metal by Gammarus also indicated that Gammarus can absorb Cd with the rate of 0/016725mg/lit/day from the environment.
