Abstract:

In order to assess the mercury(Hg)pollution in urban stormwater runoff in Nanjing, 11 rainfall events in the Maqun region of Nanjing circle expressway were monitored, and the events mean concentrations(EMC)of Hg and the impact of rainfall characteristics on Hg pollution in runoff were analyzed. Results show that the pollution of different Hg species is serious, and total Hg(THg), dissolved Hg(HgD)and particulate Hg(HgP)are found to be in the range of 0.173 to 3.347, 0.069 to 0.862, and 0.104 to 2.485 μg/L, respectively. The average EMC value of THg exceeds the Ⅴ class limitation value of “Quality standards of surface water environment(GB 3838—2002)” of China. Hg in runoff mainly exists in particulate form, and the concentrations of Hg^re(0.250 to 2.821 μg/L)are far more than those of Hg⁰(0.023 to 0.215 μg/L)and Hg²⁺(0.026 to 0.359 μg/L). The order of rainfall characteristics impacting on Hg pollution in runoff is dry periods> runoff time> duration of rainfall> storm intensity> rainfall.
