| Abstract: | A combination of mercury vapor field investigation technology and Zeeman mercury analyzer in the city multipurpose geochemical survey was introduced It was verified by experiments that the mercury in air and soil gas captured by gold adsorbent glass tube was effective and stable.The analysis uncertainty was 0.44 pg(double S.D.).As an example,the East-West and North-South profiles which contained 70 points had been investigated reapeatedly for 7 months in Beijing,it was found that the content of soil gas mer... |
