污染

Agricultural non-point source pollution is entirely different from that of point sources in their generation and transportation, so special methods have to be derived to internalize its external diseconomy.

There were different contamination conditions for different PAHs components in soils. Soils in urban area were severer contaminated by the height-weight-molecule PAHs than soils in agriculture area. However, there were the similar contamination level among different usages soils for the light-weight-molecule PAHs, such as naphthalene and methylnaphthalene.

不同种类的PAHs对不同利用类型土壤的污染情况也不相同，分子量较大的多环芳烃与总PAHs污染情况相似，表现为城市用地的污染程度要明显高于其它类型土壤；但分子量较小的组分，如萘和甲基萘，在不同利用类型土壤中污染程度相近。

The results showed that indoor air pollution by CO,NOx,and TSP washeavy in olb darracks with coal stoves in winter,but SO2 concentration was within standard in winter and summet.

结果表明，三市上述六项指标夏季大多在标准以内；冬季CO、NOx、CO_2、总悬浮颗粒物均超过标准，苯并芘冬季高于夏季，室内高于室外，旧营房高于新营房；以沈阳大气质量指数评价夏季哈尔滨新营房属"清洁"，余为轻污染，冬季哈尔滨新营房为轻污染，其余新营房为中污染，长春与锦西旧营房为极重污染。

The authors investigated the environmental-geological conditions of a certain refuse landfill site in Beijing and the ability of strata to prevent refuse pollution and monitored groundwater pollution by refuse for one consecutive hydrologic year.

通过对北京某垃圾场所处的环境地质条件、地层对垃圾污染物的防护能力的调查及对地下水连续1个水文年的污染监测，用单因子和多因子(综合污染指数和内梅罗污染指数)2种方法，评价了该垃圾场对地下水的污染情况。

The fifth chapter: regionally environmental program. Through argument of environmental reasonability of general program, set down the control goals of waste gas, waste water discharging, sound pollution and solid waste, and established preventing program of pollution and ecological environment..
