| 摘 要： | 利用欧洲标准样作控制,对比研究了土壤总Hg测定的3种消解方法,并对浦东垃圾焚烧发电厂周围土壤总Hg的背景值进行了初步研究,结果发现浦东土壤Hg背景值达到192.68 ng/g,明显高于其它城市,这与上海的工业历史、农业施肥习惯有关,值得注意的是浦东地区土壤中的气态Hg(一个样品除外)含量都很高。

| Abstract: | With the European standard samples as benchmark, three soil digestion methods for measuring total mercury in topsoil were compared and studied. They are: (1) concentrate HNO3 and concentrate HCl (1:3), and (2) concentrate HNO3, concentrate H2SO4, and KMnO4, (3) H2SO4 (1:1) and KMnO4. They are all applicable. The soil in the surroundings of the garbage-fueled power plant was investigated for mercury background value in the topsoil. Results show that it reached 192.68 ng/g, in Pudong, significantly higher than that in any other cities, which may be related with the histories of the local industry and the fertilization in agriculture. What should be noted is thatthe content of gaseous mercury in the soil was also very high ranging from 10.69 % ~ 92.06 %, with a mean value of 48.73 %. |
