综合环境社会经济指标的优先污染物筛选方法研究:以电子废物拆解为例

电子信息技术的快速更新迭代以及日常生活中的正常使用造成的磨损，导致众多电器电子产品被淘汰，产生了大量的电子废物，因此电子废物拆解量逐年增加.针对当前我国电子废物拆解污染现状和监测评价的需求，提出利用层次分析法和系统聚类方法相结合的筛选模型.在对电子废物拆解评价因子进行赋值和评分的基础上进行层次分析，得出污染物综合评分并进行聚类分析，将聚类结果中潜在危险优先等级最高的一类，即二（口恶）英类和多环芳烃（PAHs）作为优先控制污染物，为中国电子废物治理提供了有参考意义的指标体系.

Research on the Screening Method of Priority Pollutants with Integrated Environmental Socio-economic Indicators: Example of E-waste Dismantling

While benefiting mankind, electronic information technology has led to the elimination of many electrical and electronic products due to its rapid update and iteration speed. In addition, the normal use in daily life causes the wear and tear of electronic products, resulting in a large amount of electronic waste. With the increase in electronic products, the amount of electronic waste dismantling has also increased yearly. Therefore, it becomes an important to accurately screen the priority control pollutants generated in e-waste process. In view of the current situation of e-waste dismantling pollution and the needs of monitoring and evaluation in China, this study proposed a screening model that combined analysis at levels and systematic clustering methods and performed a comprehensive score of pollutants and cluster analysis on the basis of assigning and scoring the evaluation factors of e-waste dismantling, taking the most potentially dangerous class in the cluster results as the priority control pollutant.
