摘　　要：中等挥发性有机物(IVOCs)和半挥发性有机物(SVOCs)是臭氧(O_(3))和二次有机气溶胶(SOA)的重要前体物质,其污染特征亟待深入研究,特别是在人为排放源集中的化工区。通过调研国内外不同化工区的中等/半挥发性有机物(I/SVOCs)的污染水平和排放特征,发现各污染物浓度水平差异与化工区入驻企业的规模、企业生产方式和自然地理气象条件等密切相关。调研发现I/SVOCs的浓度水平低于挥发性有机物(VOCs)的浓度水平2∼3个数量级,但最近的烟雾箱实验、模型预测和外场观测研究结果均显示I/SVOCs对O_(3)和SOA的生成贡献与VOCs相当,甚至高于VOCs。梳理该类污染物的排放特征可为化工区I/SVOCs的污染机理研究和精准防治提供参考。Intermediate volatile organic compounds(IVOCs)and semi volatile organic compounds(SVOCs)are important precursors of ozone(O_(3))and secondary organic aerosols(SOA),and their pollution characteristics need to be further studied,especially in chemical areas with concentrated anthropogenic emission sources.By investigating the pollution level and emission characteristics of intermediate and semi volatile organic compounds(I/SVOCs)in different chemical zones at home and abroad,it is found that the difference of pollutant concentration level is closely related to the scale,production mode and natural geographical and meteorological conditions of enterprises settled in the chemical zone.The investigation found that the concentration levels of I/SVOCs are 2∼3 orders of magnitude lower than those of volatile organic compounds(VOCs).However,recent results from laboratory photo-oxidation,model predictions and outfield observation studies have shown that the contribution of I/SVOCs to O_(3)and SOA production is comparable to,or higher than,that of VOCs.Combing the emission characteristics of these pollutants can provide reference for the pollution mechanism research and precise prevention of I/SVOCs in chemical industry.
