Abstract :

Heavy metal pollution of water sources due to discharge of factories into environment is the highest riskfor human and environment health. Humans and animals by consuming vegetables and food staff washedwith polluted water are at high risk. The quality of surface waters is a very sensitive issue. Sampling forwatershed was carried out over 4 months (April, May, June and July) from 6 stations and qualityparameters were determined. These parameters are: pb, Zn, Cu, Cd, Ni and Fe. Also the data wereanalyzed with standard methods and atomic absorption. Results showed that in April the highestaverage was that of pb (.0.54 mg/l) and the lowest cadmium (0.001 mg/l ). In May, the highest averagewas related to pb (1.15mg/l) and the lowest its was Fe (0.013mg/l ). In June the highest and lowestaverages were Cu(.0.56 mg/l) and Fe (0 mg/l) respectively, while also in July they were Cd (0.018 mg/l)and Fe(0 mg/l). The River was polluted with heavy metals in some stations and water quality of this riverdoes not matchwith standards. With physical, chemical and biological agent monitoring and also withcontrol of water quality indexes in these stations, we observed wastewater and other pollution arrive river.Environmental effects of pollution are seen in different parts of the river.
