文章应用苏码罐采样,预浓缩系统与GC-MS联用测定环境空气中39种挥发性有机物,结果表明淮安空气中以苯系物浓度较高,范围为4.80~59.68μg/m3,以甲苯和苯浓度最高;VOCs浓度范围为5.88~66.50μg/m3;空气中甲苯浓度高于苯,说明其主要来源于汽车尾气。
文章應用囌碼罐採樣,預濃縮繫統與GC-MS聯用測定環境空氣中39種揮髮性有機物,結果錶明淮安空氣中以苯繫物濃度較高,範圍為4.80~59.68μg/m3,以甲苯和苯濃度最高;VOCs濃度範圍為5.88~66.50μg/m3;空氣中甲苯濃度高于苯,說明其主要來源于汽車尾氣。
문장응용소마관채양,예농축계통여GC-MS련용측정배경공기중39충휘발성유궤물,결과표명회안공기중이분계물농도교고,범위위4.80~59.68μg/m3,이갑분화분농도최고;VOCs농도범위위5.88~66.50μg/m3;공기중갑분농도고우분,설명기주요래원우기차미기。
Pre-concentrated system combined GC-MS was evaluated for determination of 39 kinds of trace volatile organic compounds（VOCs） in ambient air using SUMMA canister for sampling.The major components were BTEX with concentration of 4.80 ？g/m3 to 59.68 ？g/m3,while the concentration of VOCs was 5.88 ？g/m3 to 66.50 ？g/m3.Concentration of toluene was higher than benzene,because of the main source is the discharge of tail gas of vehicles.
