Abstract:
Shellfish Fur (Anadara antiquata sp) is one type of shellfish which often consumed
commonly. These type of shellfish is very well to be used as an indicator of water
pollution level, because it has the properties of filetring foods and a sedentary life. This
study aims to analyze the concentrations of heavy metals Pb, Cd and Cr in shellfish fur
(Anadara antiquata sp) and the seawater in Dumai. The method of this research is
purposive. The highest concentration of Pb in shellfish fur (Anadara antiquata sp) at
station 3 is 3,5116 mg/Kg, where as the highest concentration in seawater at Station 3 is
0,1214 mg/mL. Based on the research result which obtains for the highest concentration
of Cd in shellfish fur (Anadara antiquata sp) at Station 1 and the seawater at Station 1
are 7,5670 mg/Kg and 0,0847 mg/mL, respectively. The highest concentration of heavy
metals Cr in shellfish fur (Anadara antiquata sp) at Station 3 and the seawater at station
2 are 1,785 mg/Kg and 0,071 mg/mL, respectively.
