Measurement of heavy metals pollution in vertical profile of chahnimeh's water (NO:3) of Zabol

Reservoirs and lakes Supply sufficient water for various purpose such as drinking، industry and agriculture. These types of water exposed constantly to variety of pollution. Due to the critical situation of these resources and the lack of previous Studies، in this research concentration of chromium، cadmium، zinc، copper، Nickel، lead، iron and manganese in vertical profile of chahnimeh’s water (no. 3) were investigated. Materials: The Cross - sectional research was performed from April to October 2012 on water of chahnimeh (no. 3) sabot. For this purpose 96 samples were collected from the depths 1، 3، 5، 7، 9، 11، 13، 15 meters and concentration of heavy metals measured by atomic absorption. The results were analyzed by using descriptive statistics and ANOVA test with regard to the significance level P < 0. 05. The average concentration of heavy metals was 0. 098، 0. 05، 0. 04، 0. 04، 0. 013، 0. 006، 0. 002 and zero mg/l for Nickel، zinc، iron، copper، chromium، lead، manganese and cadmium، respectively. In comparison of results with ISIRI recomendatins are concluded that concentration of all heavy metals except Nickel were acceptable. Significant correlation (P < 0. 05) was not observed between the concentration of heavy metals and depths. The results indicated that no significant heavy metals pollutions in the reservoir were available.
