Research Abstract

Distribution of mercury around small scale gold mining area had been investigated. The atmospheric concentration of mercury in the village was several μg m-3and that in the work place was 30 μg m-3. The highest concentration of mercury in river water was about 10 μg L-1.In soil samples, total mercury and methylmercury concentrations decreased with depth from the soil surface. The values showed significant positive relations with total organic carbon content. The fact suggests that the transported mercury through the air deposits on the ground surfaces and adsorb on the organic matter.
