污染

Results show that as a whole the region is quite good in soil environment quality, except for Wushan and Fengjie districts, where high Cr and Ni background values have led to existence of a certain area of Grade Ⅱ soils. Over 90% of the soils are in Grade Ⅰ in terms of As, Cu, Hg, Pb and Zn. Artificial pollution is local and limited in area. For instance, spots of Hg pollution are found only in the vicinity of residential settlements, factories and minings.

结果表明：三峡库区区域土壤环境质量总体上较好，除巫山、奉节地区Cr、Ni自然高背景导致存在一定量的区域性二类土外，表层土壤中As、Cu、Hg、Pb、Zn等元素一类土占全区面积均在90%以上，仅存在局部性人为污染，如Hg在城镇、厂矿等地的点状污染；不存在区域性的人为污染。

This research discussed the treatment of the Fenton's agent of the in-situ chemical oxidation on contaminated groundwater polluted by benzene, toluene, ethylbenzene, and xylenes released from gasoline. The above treatment was evaluated by virtue of the literature review, principle of remediation, removal efficiency, real remediation cases and cost in order to clearly understand its merit, constraints, the best way to implement and to provide the domestic practitioners for assessing the remediation technique considering the economic benefit and the remediation schedule.

中文摘要本研究探讨以现地化学氧化法(in-situ chemical oxidation， ISCO)之Fenton's试剂处理汽油中苯、甲苯、乙苯、二甲苯(benzene、toluene、ethylbenzene、xylenes，BTEX)污染地下水之实际案例，经由相关文献资料、整治原理、去除效率、现场整治案例成效及成本等进行评析，以更清楚掌握其优点、限制及最佳之施用方法，做为国内相关人员在经济效益及污染整治时程上考量，评估该污染整治操作技术之应用参考。

Compared with the single pollution, the eco-toxicity of compound pollution of As+Cd and Cu+Cd becomes stronger, which preemie a synergistic effect, as far as the lethal concentration to the cell of duckweed's lemma is concerned; As+Cu and As+Cu+Cd is inclined to an antagonistic effect of which the eco-toxicity of compound pollution becomes weaker.

与单一污染相比，As+Cd和Cu+Cd复合污染对浮萍叶绿素毒性增强，表现为协同作用，加强了对浮萍叶细胞的伤害；而As+Cu和As+Cu+Cd复合污染对叶绿素联合毒性作用趋向于毒性减少的拮抗作用。

With consider of characteristic of indoor Pollution and influence of the health of human body by excessive pollutive factor value.under the foundation of environmental quality evaluation technique, apply the concept of the indoor air evalation of quality to pollute the comprehensive evaluation index of factor, reflect the influence of indoor air contaminant for the health of human body.

Every year, waters on earth receive large quantities of wastewater from industry, agriculture, fish and poultry raising, and municipal sewage treatment plants. Consequently, the aquatic environment on the earth is under a serious challenge from a very large quantity of pollutants such as antibiotics, insecticides, herbicides, hydrocarbons, etc., contained in the domestic wastewater, industrial and agricultural waste water and illegal effluents. In particular, with the development of intensive aquiculture and poultry, the effluent pollution has recently become more and more serious with more attentions. Furthermore more and more chemical pollutants discharged into aquatic environment have been detected with the advancement of analytical techniques. These chemicals can cause toxic effects on water habitats after discharged into aquatic environment.

每年有大量来自工业、农业、养殖业和城市污水处理厂的废水被排入到水环境中，因此，地球上的水环境面临大量来自生活废水、工农业废水、非法排放的废水及其它废水的污染物质(如抗生素、杀虫剂、除草剂、烃等)的严重挑战，特别是近年来随着集约化养殖的发展，废水污染问题日益突出，并且随着分析手段的进步，能够检测到被排入水环境中的化学污染物质也越来越多，这些化学污染物对水环境中的生物产生有害影响。

In this paper, an attempt is made to predict the applied prospects of reed at water-lever-fluctuating Zone in the Three Gorges Reservoir Region by analyzing the present situation, in other words, reed may prevent water erosion, eutrophication in water, heavy metal pollution, solid castoff pollution, garbage infiltration and water pollution, the overrunning of algae and so on.
