    A study on the concentration and distribution of heavy metals Pb, Cu and Zn in seawater, sediment and Snail Telescopium telescopium from coastal waters around shipyards in Batam has been conducted. Samples were taken from four stations and heavy metal analysis was carried out by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science University of Riau. The mean concentrations of Pb, Cu and Zn were 0.424; 0.057; 0.057 mg/L in seawater, 45.392; 129.688; 181.325 μg/g in sediment and 49.271; 87.663; 138.900 μg/g in T. telescopium, respectively. Higher concentration of Pb in T. telescopium than in sediment and seawater was found, whereas Cu and Zn were higher in sediment than in snail and seawater. Concentrations of Pb, Cu and Zn in seawater were possitively correlated with those in both sediment and snail and concentrations of those metals in sediment were also possitively correlated with those in snail. In general, the concentrations of Pb, Cu and Zn in coastal water around shipyard in Batam was higher than in coastal waters with no shipyard industry and they were still generally comparable to those reported values in regional studies. Mean concentration of Pb in sediment was nearly reach the ERL values whereas Cu and Zn already exceeded the ERL but still lower than ERM values. Continuous environment monitoring programs should be implemented.in Batam coastal waters since rapid developments in many infrastructure and industry sectors is taking place
