9、all kinds of social , economic , and cultural aspects. Such broadness is unworkable in many real situations and impractical in a text book designed for a one semester course. Our examination of environmental problems is therefore limited by our definition of“environment” .当改善环境质量的目标是用来改善人类的福祉,“ 环境”这

10、个词扩大到包括社会,经济,文化等全部方面的内容；这种扩大化在很多实际情形下是不行行的,在本被设计为一学期课程的教科书中也是不切实际的；因此,我名师归纳总结 - - - - - - -第 1 页,共 30 页精选学习资料 - - - - - - - - - 们对环境问题的考察限于我们定义的“ 环境” ；Interaction of Systems 互动系统 A number of different environmental problems areassociated with water,air,or land systems. 很多不同的环境问题都涉及 到水,空气,或土壤；Many of

40、mping of hazardous materials into the rivers and streams was eliminated, those same materials created other disposal problems. 随着往河道排放有毒物质的习惯的排除,但这些相同的物质造成了其他处理问 题；Many of the chemicals saved from the sewer were either worthless or of such a low value as to render recovery uneconomical. 在下水道中回收到的物质不

41、是没价值的就是低廉到不足以复原利用 .In some cases, recovery was technically impossible. As a result, the waste chemicals were disposed of by any convenient method. 一些情形下 ,回收在技术层面上是不行能的 .所以 ,很多废弃的化学药物都被很简洁地扔掉了 .暂时的垃圾场已经不 The makeshift dumps sites were expanded.

46、rns,the United States Congress enacted a new legislation that dealt with the issues of disposal of hazardous wastes.由于这些担忧,美国国会通过了一个新的处理有害废物过程中显现问题的法规；This was the Resource Conversation and Recovery Act of 1987. 这就是 1987 年的资源回收爱护法；The purpose of the Act was to allow regulation of hazardous substance

47、 disposal. 的方法；这项法案的目的是同意有害物质处理As a result, industries that generated large quantities of these waste materials now had to ensure that the materials were disposed of in the a manner that was safe for the environment. 结果导致产生大量废物的企业现在不得不确保这些物质 被以对环境安全的方法处理；Many of the improper dumps that were created prior to the RCRA legislation were created by persons with little or no financial resources. 在资源回收爱护法由很少或者没有经济资源的人确立之前,很多不合理的堆放已经造成；As a result, the cleanup of the old sites has been taken over by the government under legislation. 使得清理旧的堆放点的 工作由政府接管；As of this
