The pollution of aquatic ecosystem by heavy metals has been assumed as serious proportions due to their toxicity and accumulative behavior. This paper deals with the measurement of four heavy metals, i.e. Cd, Cr6+, Cu, and Zn. Grab samples of water for one year period (March, June, and November) were collected from 6 different sites following the Standard Methods. Water samples of this river ware processed and analyzed for heavy metal using AAS. The heavy metal found in the river water were in range of: Cd (0.00 to 0,01 mg\/L); Cr6+ (0.03 to 0.18 mg\/L); Cu (0.00 to 0,08 mg\/L); and Zn (0.00 to 1.44 mg\/L). Some physic-chemical parameters which were dissolved oxygen, BOD5, and COD were also estimated as they have direct or indirect influence on incidence, transport and speciation of the heavy metals. Based on the findings, the Citarum river water can be considered as polluted with respect to Cd, Cu, Cr6+, and Zn.<\/p>\n
