摘　　要：以EPA TO-15的64种挥发性有机物(VOCs)为基础,剔除其中7种毒性比乙醇低的物质,同时增加了27种毒性大于乙醇的物质,建立挥发性有机毒性污染物(VOTCs)清单,并采用当量加权法对空气和废气中挥发性有机物进行综合生物毒性评价。结果表明,挥发性有机毒性物质综合毒性可以很好地反映VOCs的综合毒性;当废气或环境空气中有多种污染物同时存在时,综合毒性值远大于单个污染物毒性值,其评价结果更接近废气的真实污染水平。64 kinds of volatile organic compounds（VOCs） of EPA TO-15 as the foundation,out of which 7 kinds of toxic substances lower than the toxicity of ethanol,while adding 27 kinds of toxic substances than the toxicity of ethanol,the volatile organic toxic pollutants（VOTCs） lists were established.The equivalent weighted toxicity evaluation method was used to evaluate the comprehensive biological toxicity of volatile organic compounds in air and waste gas.The results show that the comprehensive toxicity of volatile organic toxicant could well reflect the comprehensive toxicity of VOCs.When there are kinds of pollutants in the waste gas or environmental air,the comprehensive toxicity is far higher than the single pollutant＇s toxicity and the evaluation result is more close to the actual pollution level of the waste gas.
