Abstract

AbstractSail River is one of polluted rivers in Riau. High Pb and Zn concentrations in the water and sediments may affects organisms living in the  rivers, including Tubifex. A study aims to understand the Pb and Zn concent in the water, sediment and Tubifexin that river was conducted in October - November 2017. There were 3 stations, in the upstream (St1), in the residential area (St2) and in the downstream (St3). Samplings were conducted 3 times,once/2 weeks. Results indicate that the concentration of Pb in the water, sediment and  Tubifex were 0.276 to 0.776 mg/L, 1.249 to 3.643 mg/kg and 3.643 to 5.613 mg/kg. While the Zn concentration in the water, sediment and  Tubifex were 0.597 to 0.785 mg/L, 62.165 to 124.329 mg/kg and 83.982 to 94.995 mg/kg respectively.  It was concluded that the water, sediments and Tubifex worms from the Sail River were already contaminated with Pb and Zn.Keywords :  Heavy metals, polluted rivers, residential area, contaminated
