Evaluation of Concentration of Heavy Metals in Chahnimeh Water Reservoirs of Sistan-va-Baloochestan Province in 2010

Background and For environmental protection, public health, and pollution control, we must have precise information about the extent of pollutants, especially, heavy metals in water environments. Having high stability, heavy metals can produce danger in living organisms. Therefore, the present research was conducted to assess the Concentration of heavy metals and compare the findings with national and international standards. The present research which was conducted in Spring 2010 is based on descriptive periodic method. During the research, a number of 48 samples from 16 stations (7 Chahnimeh Stations 1, 5 Chahnimeh Stations 2, 4 Chahnimeh Stations 3) were gathered and Concentration of heavy metals (iron, copper, lead, Boron, nickel, vanadium, cadmium, selenium, chrome, arsenic, and mercury) was measured by ICP-OES. The findings resulted from the analysis of samples and their comparison with standard levels showed that the average Concentration of chrome in Chahnimeh No. 1 is beyond the national and World Health Organization. (WHO) standard level and average Concentration of cadmium, nickel, and lead in Chahnimeh No. 1, and cadmium and lead in Chahnimehs Nos. 2 and 3 are beyond World Health Organization, (WHO) standard level. In the recent years, numerous researches have shown that different polluting materials like metal elements are transferred to waters through different natural and artificial (human activity) ways which biological control can prove to be a desirable and satisfactory method for measuring the level of heavy metals and their biological accessibility. As such, planning for constant control of water reservoirs seems to be necessary.
