摘要：Aq-Darreh mining district is located in the Aq-Darreh River watershed. The water and river-bedsediments of this area are much polluted due to the severe weathering and erosion of waste piles of Aq-Darreh Bala abandoned Sb mine and Aq-Darreh Au deposit. The concentration of As and Sb in water ofAq-Darreh River ranges from 3.2 to159 μg/l and 1.32 to 54.00 μg/l, respectively. Also the amount of As,Sb and Hg in the Aq-Darreh river-bed sediments ranges from 38.6 to 1087.4 mg/kg (As), 1.87 to 93 mg/kg(Sb) and 0.096 to 23.7 mg/kg (Hg). Detailed chemical analyses of water and bed sediments samples ofAq-Darreh River and its distributaries indicate that geochemical background of this area, and alsomining activities are responsible for these high concentrations of toxic elements. According to theanalytical results (As, Sb and Hg concentrations) and their comparison to world river average values, itis concluded that Aq-Darreh River is amongst the very polluted water bodies of the world.
