摘　　要：于泡沫塑料鞋制造集中区和周边设置了5个采样点,研究其大气VOCs的污染特征和对臭氧生成的潜在影响.结果显示泡沫塑料制鞋行业大气VOCs组成以烷烃(38.4%)、含氧挥发性有机物(33.5%)和芳香烃(19.5%)为主,80种VOCs浓度为137.1~169.0μg/m^3(均值149.1μg/m^3).正戊烷、异戊烷、正丁烷、异丁烷、甲醛、甲苯、间/邻二甲苯、丙酮、丁酮、环己酮、甲基丙烯酸甲酯、乙酸乙酯为泡沫塑料鞋制造行业的特征VOCs.总VOCs、特征VOCs类型(含氧挥发性有机物、芳香烃)和特征VOCs组分(甲苯、邻二甲苯、间二甲苯、丁酮、乙酸乙酯)的浓度空间变化趋势依次为污染区>受影响区(下风向)>对照区(上风向).同时,采用最大增量反应活性(MIR)方法估算了VOCs的臭氧生成潜势(OFP),均值为544.6μg/m^3,表明泡沫塑料鞋制造导致了周边环境空气VOCs污染且对臭氧生成存在明显潜在影响.Five monitoring sites were set up in and around the plastic foam shoe manufacturing center in Wuchuan,Guangdong to study the pollution characteristics and ozone formation potentials of atmospheric VOCs.The results showed that the composition of atmospheric VOCs was predominantly alkanes(38.4%),oxygen-containing VOCs(33.5%),and aromatic hydrocarbons(19.5%).The total concentration of 80 kinds of VOCs ranged from 137.1μg/m^3 to 169.0μg/m^3 with an average of 149.1μg/m^3.N-pentane,isopentane,n-butane,isobutane,formaldehyde,toluene,m/o-xylene,acetone,methyl ethyl ketone,cyclohexanone,methyl methacrylate,and ethyl acetate were characteristic VOCs of this shoe manufacture industry.The spatial trends of the total VOC concentrations,characteristic VOC types(oxygen-containing volatile organic compounds,aromatic hydrocarbons)and characteristic VOC components(toluene,o-xylene,m-xylene,methyl ethyl ketone,and ethyl acetate)all showed a spatial pattern that the concentration was largest at contaminated area,followed by affected area(downwind)and control area(upwind).Additionally,the ozone formation potential(OFP)of VOCs was estimated with the maximum incremental reactivity(MIR)method.The mean value of OFP was 544.6μg/m^3,indicating that the manufacture of plastic foam shoes tended to cause the pollution of ambient VOCs and have a significant impact on ozone formation.
