The results showed that the average concentration of Hg, Cd and Cu in Ancol beach 1 were <0.001 ppm respectively, Pb is 0.001 ppm, Zn is 0.004 ppm, and Ni is 0.001 ppm. In Ancol beach 2 the average concentration of Hg, Cd, and Zn were <0.001 ppm, Pb is 0.002 ppm, Cu is 0.001 ppm and Ni 0.0017 ppm. In Cilincing the average concentration of Hg, Cd, and Zn were
