| 摘 要： | 调查研究表明：在山地大气、水体质量较好的环境中，柑橘（含汞量）有超标问题，其土壤汞有超背景值现象；而蔬菜土壤则无此问题，其原因可能是由于多年生植物从大气和土壤中富积微量汞的时间较一年生植物长，以及土壤中砂粒结合汞粘粒结合汞具有更高的生物活性

| Abstract: | Researches indicated that in mountaion regions where air and water were in good quality,Hg in soil was closing to or overstepping its background value(B.V.),Hg in crops was high in orange and low in vegetables.This could be related to that the time of the perennial plant accumulating the trace Hg from air and soil was much longer than that of the annual plant,and that the Hg in sandy soil could be more bioavailable than that in clay soil. |
