| 摘 要： | 进入土壤和天然水体中的有害元素,对环境质量造成影响,其影响程度在区域化探资料上有反映,可采用水系沉积物背景值、污染起始值、污染指数等参数来评价环境质量,圈出污染区和划分污染等级。据1/200 000株洲幅区域化探资料,计算Cd、W、Ag、Bi、Hg、Sn、Pb、Mo、Zn、F、Cu、U、As、Ba、Sb、Be、P、Cr等18个元素各项污染参数,圈出50多处污染区,中等污染程度达21处,以Cd、W、Ag、Bi、Hg等污染严重、污染面广、危害较大,並对潘家冲、贺家桥两个污染区的环境质量作了具体评价,指出工厂、矿山排放的“三废”为污染源,应有效地进行治理。

| Abstract: | The harmful elements in soil and natural water mass will influence the quality of the environment, The degree of influence is inflected in the regional geochemical exploration data. The background value, initial value of pollution, pollution index and other parameters of stream sediments can be used to make assessment of environmental quality, to delineate polluted areas and to divide the pollution levels. According to 1/200000 scale regional geochemical exploration data in Zhuzhou area, the pollution parameters of 18 elements (Cd, W, Ag, Bi, Hg, Sn, Pb, Mo, Zn, F, Cu, U, As, Ba, Sb, Be, P, Cr) are calculated, 50 more pollution areas are delineated, among which 21 areas are moderately polluted, especially Cd, W, Ag, Bi, Hg pollutions are serious and extensive and relatively harmful. Concrete assessment is given for the environment quality of Panjiachong, Hejiaqiao two pollution areas, lt is pointed out that the three wastes discharged from factory and mines are pollution sources, which must be put into effective control. |
