室内外空气污染暴露评价

介绍了国外对室内外空气污染暴露评价的各种方法，并运用微环境结合问卷调查的方法，选择了5种主要的空气污染物；甲醛、二氧化硫、氮氧化物，氮和氡作为检测评价的对象，初步评价了北京市各年龄层次人群的污染物暴露水平。结果表明，大部分暴露量源于室内环境，尤其是工作（或学习）场所及住宅；各年龄层次人群的甲醛日平均暴露量均超过相关环境标准，而其它污染物均不超标；室内空气污染特别是因装修引起的室内空气污染应得到重视。

Exposure Assessment on Indoor and Outdoor Air Pollutants

Applying the scenario analytical method to the control planning of water pollution, a series of different schemes were designed according to economic development and prediction of pollution discharge in Gan river. After simulation, using water quality model and expense estimation, several suitable schemes were chose at the first stage. Through further multiattribute decision analysis from water quality, outlay, operation and social effect, the best scheme could be recommended to the decision-maker.
