Abstract:   (1236 Views)
Background: Entry of heavy metals into water resources through different routes has caused some dangers such as toxicity, cancer, etc., for living animals. Abshineh River is one of the most important rivers supplying the drinking water of Hamedan, Iran. The present study aimed at investigating the amount of heavy metals including Zn, Cu, Pb and Cd in this river.   Methods: This was a cross-sectional study and based on health importance,4 heavy metals including Zn, Cu, Pb and Cd were analyzed by means of standard methods.Quarterly sampling (December 2011, February 2012, April 2012 and August 2012)was carried out in 7 stations. A total of 84 samples (21 samples in each season) were collected in tightly-closed one-liter bottles. Sample digestion was performed through evaporation method and heavy metal concentrations were measured by ICP. Data were analyzed through SPSS16 and single sample t-test with confidence levels of 95% was used to compare means of each heavy metal with WHO standards while ANOVA test was used to compare mean amount of metals among the sampling stations.   Results:­ Mean and standard deviation of Zn, Cu, Pb, and Cd in four seasons were respectively (0.06292 ±0.04157), (0.00308 ±0.00526), (0.01436 ±0.02082) and (0.00127 ±0.00100) mg/lit. So, the amount of heavy metals in Abshineh River, except for Pb in spring, is about the standard level for drinking consumptions.   Conclusion: Regarding the findings of this study, Abshineh River was a safe source to supply drinking water in terms of the measured metals during the time of the study. Nevertheless, it is suggested that the amount of heavy metals, particularly Pb, in this region is measured regularly.
