The present study shows that stream water and sediment in the To-Lich and Kim-Nguu River are heavily polluted with heavy metals, and the metal concentrations all exceed the Vietnamese surface water standard. The metal concentrations in the water and sediment were indicated to be closely related to the type of manufacturing plants located along the rivers. The high concentration of Cu is due to discharges from textile manufactures. The metals such as Zn, Cr, and Ni were released from the battery factory located at Van-Dien area. Cadmium is derived from Dai-Kim plastic factory, and Pb can be attributed mainly to transportation activities.
