| dc.description.abstract | Discovery of natural resources such as gold in Kuantan Singingi Riau province increased the gold mining in the watershed singingi which break the balance of ecosystem. Accumulation of Cd causes kidney disfunction and cause injury on nose duct. A high concentration of nitrate ion causes an uncontrolled growth of algae and other plants which decreased the concentration of oxygen dissolved in water. In this study, the contribution of heavy metal Cd and nitrate to Singingi river’s water was analyzed. The concentration of Cd was determined by Atomic Absorption spectrophotometry, while nitrate ion was determined by the brucine sulfate method and analyzed by visible spectrophotometer. Water samples were taken at 10 stations along the river singingi. The results showed that the Cd content was not detected, while the highest nitrate content was found in the 10th station, i.e. 1.582 ppm | en_US |
