《Measurement and Scaling of Mercury on Soil and Air in a Historical Artisanal Gold Mining Area in Northeastern China》
The summary of TGM measured seasonally from all sampling sites is shown in Table 1.The data indicate that the mean TGM was(55±21)ng/m3 in the research area during the sampling period,and those in Jiapigou Township,Wudaocha,Sandaocha,Erdaocha,Laojinchang and Erdaogou were(56±33)ng/m3,(33±13) ng/m3,(116±28) ng/m3,(94±33) ng/m3,(22±8) ng/m3 and(24±10)ng/m3,respectively.These values were obviously higher than those shown in the previous study(Wan et al.,2009),in which it was reported that the annual mean value of TGM was(3.22±1.78)ng/m3 on Changbai Mountain,the highest mountain in Northeast China.The monitoring values in this campaign were also much higher than the TGM background value(1.5–2.0 ng/m3)of the Northern Hemisphere(Ebinghaus et al.,2002;Lamborg et al.,2002;Steffen et al.,2002).
