《Measurement and Scaling of Mercury on Soil and Air in a Historical Artisanal Gold Mining Area in Northeastern China》
Note:n=32.
Among the six sites,the statistical summary of Hg flux between soil and air in winter and spring at the four representative ones,that is Jiapigou Township,Erdaocha,Laojinchang and Erdaogou is shown in Table 3.The mean flux values were(7±46)ng/(m2·h),(23±171) ng/(m2·h),(129±496) ng/(m2·h)and(99±44)ng/(m2·h)in spring,and(–13±7)ng/(m2·h),(–24±18) ng/(m2·h),(–21±16) ng/(m2·h)and(–4±9)ng/(m2·h)in autumn,respectively.In spring the Hg flux was mainly released from the soil to air,but in winter the reverse was true,deposited primarily from the air to soil.According to flux data illustrated in Table 3 and the area50–150 km2 of Jiapigou gold mine,it was estimated that around 8–24 t Hg were released from the contaminated soil by Au mining activities(for 7 months)and 1–3 t Hg were deposited to the snow cover in winter(for 5 months),and more details on net Hg output from the earth surface to the air in artisanal Au mines need further study.
