BCR Speciation Analysis of Mercury in Smelting Slag at Yunnan Arsenic Mining Area

Abstract:

BCR three-step extraction method was used to evaluate the speciation of mercury in mining area soil. The results showed that the major existent form of mercury in NO.1 and NO.3 area were acid-soluble speciation, the major existent form of mercury in NO.2 and NO.4 area were nitric acid-soluble speciation, and the total content of mercury in entrance area, shade area, sunny area and low-lying area were 419.977 mg/kg, 182.945 mg/kg, 290.313 mg/kg and 798.718 mg/kg, respectively. The bioavailability of mercury in mining area soil was evaluated based on BCR speciation. Acid-soluble speciation, nitric acid-soluble speciation and oxidation speciation were considered to be potential bioavailability.
