摘要
采用在水污染控制规划中有广泛应用的情景分析法,从流域水环境功能分区出发,根据赣江流域各市县的社会经济发展规划和污染源排放量的预测结果,对流域的水污染控制设计了一系列不同的情景方案。首先通过情景水水质模拟和情景经济分析,初选出适用的方案,再运用多目标决策方法,从水质、经费、施工、社会影响等方面进行综合评定。据此定出筛选方案优劣和先后的顺序,并提出赣江流域水污染控制规划的推荐方案。研究表明,情景分析方法对于流域的整体规划在综合性、完整性、可持续性等方面具有着良好的指导意义。
Several kinds of exposure assessment methods have been introduced in this paper. The average concentrations of five air pollutants, including formaldehyde, nitrogen oxides, sulfur dioxide, ammonia and radon were obtained from monitoring in major microenvi-ronments together with questionnaires, were used to assess the exposure levels of different age groups of people in Beijing. The results showed that most of exposure came from indoor environments, especially from workshops (or studying rooms) and residences, and also indicated that only 24-h CH2O exposure for all age groups exceeded the standards. Indoor air pollution, especially due to indoor decoration, should be paid more attention.
