摘　　要：采用苏玛罐采样-GC/MS法分析西安市家具制造、表面涂装、汽车整车制造和印刷行业VOCs成分谱,计算不同工序VOCs对O 3和二次有机气溶胶(SOA)的生成贡献。结果表明:西安市不同行业TVOC排放值为0.332 mg/m^(3)~45.7 mg/m^(3),涂装行业最高,其次是印刷工序和木质家具制造,汽车软装和印刷覆膜工序较低。木质家具VOCs主要为芳香烃、含氧类有机物和烷烃,随着油性漆替换为水性漆,芳香烃占比下降,含氧类有机物占比上升。汽车喷涂VOCs主要为芳香烃和含氧类有机物,印刷行业VOCs中含氧类有机物占比高。表面涂装排放VOCs对生成O 3和SOA贡献最高,印刷行业R OF最小,汽车软装工序R SOA最小。The source profile of VOCs in furniture manufacturing,surface coating,automobile manufacturing and printing industries in Xi'an were analyzed by Suma canister collecting-GC/MS.The contribution of VOCs from different processes to the generation of O 3 and secondary organic aerosol(SOA)was calculated.The results showed that TVOC mass concentration from different industries in Xi'an was from 0.332 mg/m^(3) to 45.7 mg/m^(3),with the highest in painting industry,followed by printing process and furniture manufacturing,and the lowest in automobile decoration and laminating process.VOCs from furniture manufacturing were mainly aromatic hydrocarbons,oxygen-containing organic matter and alkane.With the substitution of oil-based paint for water-based paint,the proportion of aromatic hydrocarbons decreased and the proportion of oxygen-containing organic matter increased.VOCs from automobile spray were mainly aromatic hydrocarbons and oxygen-containing organic matter.The proportion of oxygen-containing organic matter in VOCs from printing industry was high.VOCs from surface coating contributed the most to the generation of O 3 and SOA.R OF of VOCs from printing industry was the smallest.R SOA of VOCs from automobile decoration process was the smallest.
