【摘要】：本文通过污染物检出率得分、毒性效应得分、人群暴露得分等,构建了一种大气健康基准目标污染物筛选方法.进而采用该方法,筛选并提出我国大气健康基准目标污染物候选清单.结果显示,共有38种污染物进入初始污染物候选名单,包括了常规污染物、重金属污染物以及大气挥发性有机物(VOCs)、多环芳烃、二英等.这些污染物检出率得分分布在0—600之间,其中最高的污染物主要是国家常规监测的污染物.污染物毒性效应得分最高的污染物是苯、PM_(2.5)、PM_(10)、二英,大部分污染物的毒性效应得分集中在300—500之间;污染物的人群暴露得分最高为CO,其次为甲苯、O_3、PM_(2.5)、PM_(10)、NO_2,得分在10—100之间;38种污染物中有15种污染物健康风险综合得分在900以上,包含6种常规污染物、2个大类污染物、2种重金属污染物、5种挥发性有机物VOCs.因而提出这15污染物作为我国大气环境健康基准目标污染物候选清单.
[Abstract]:Based on pollutant detection rate score, toxicity effect score, population exposure score and so on, a screening method for target pollutants in atmospheric health benchmark was constructed in this paper. Screening and proposing a candidate list of pollutants for China's atmospheric health benchmark. The results show that a total of 38 pollutants have entered the initial candidate list of pollutants, including conventional pollutants. Heavy metal pollutants and atmospheric volatile organic compounds (VOC), polycyclic aromatic hydrocarbons (PAHs), dioxins, etc. The detection rates of these pollutants ranged from 0 to 600, The highest pollutant is mainly monitored by the state, and the pollutant with the highest score of toxic effect of pollutants is benzene-PMSP 2.5 / PMSP 10, dioxin, and most of the toxic effects of pollutants are between 300-500; The highest exposure score of pollutants was COO, followed by toluene O _ 3P _ P _ P _ T _ (2.5) / _ _ _. There are 6 kinds of conventional pollutants, 2 kinds of heavy metals, 2 kinds of heavy metal pollutants and 5 kinds of volatile organic compounds (VOCs).
