南宁市内河沉积物的汞含量及其潜在风险OACHSSCD

The sediment accumulated in urban inland rivers is an important component of the inland river water environment and has become a potential source of secondary pollution.Based on the detection results of sediment and water samples from 19 inland rivers in Nanning city,this paper analyzes the total amount and effective state of mercury in inland river sediments,compares the mercury leaching concentration of sediments in inland river and pure water environments,and evaluates the impact of mercury activity and migration trends in inland river sediments on the quality of inland river water environment.The experimental results indicate that mercury in the sediment of the inland rivers in Nanning city has no significant potential risk to the quality of the inland river water environment.
