摘要

摘要: 基于层次分析法,构建了包含化学品毒性效应和环境效应2类危害性影响因素、共8项指标的化学品危害性综合评价体系;将该评价体系应用于南方某市优先控制化学品,梳理了该市相关法律法规、污染源普查数据和美国有毒物质数据库,对化学品的原辅材料及其实际使用情况进行分析,确定了优先控制化学品初选清单;对化学品危害性进行了计算,最终确定了环境管控风险值,从而筛选识别出该市优先控制化学品清单。结果表明,该市化学品初选清单共包括23种化学品,环境管控风险值较大的优先控制化学品包括十溴二苯醚、六溴环十二烷、壬基酚、短链氯化石蜡4种,主要涉及橡胶、塑料、纤维、电子产品、金属加工等行业或领域。建议针对该市优先控制化学品深入开展全生命周期环境影响评价,并将源头减量、过程控制和末端治理相结合,减少优先控制化学品的环境风险。

Abstract: A comprehensive evaluation system of chemical hazard including 2 hazardous influencing factors, i.e. toxic effects and environmental effects, and 8 indicators was constructed based on the analytic hierarchy process. This evaluation system was applied to the priority control chemicals of a city in southern China. The relevant laws and regulations of the city, US toxic substance database and pollution source survey data were sorted out. The raw and auxiliary materials of chemicals and their actual use were analyzed. And the primary list of priority control chemicals was determined. The calculation of the hazards of chemicals was carried out, and the environmental priority control risk values were finally determined, so as to screen and identify the city’s priority control chemical list. The results showed that there were 23 chemicals in the primary list of chemicals in the city, and the chemicals with higher risk values for environmental priority control were decabromodiphenyl ether, hexabromocyclododecane, nonylphenol, and short-chain chlorinated paraffins, which were mainly involved in rubber, plastics, fiber, electronic products, metal processing and other industries or fields. It was recommended to conduct an in-depth full life cycle environmental impact assessment for the city’s priority chemicals, and combine source reduction, process control and end treatment to reduce the environmental risks of priority chemicals.
