VOCs是臭氧（O₃）和二次有机气溶胶（SOA）的重要前体物。调研了印刷、家具、制鞋、涂料、喷涂、汽车、电子等典型溶剂使用行业不同地区VOCs的源成分，采用MIR（最大增量反应活性系数）、FAC（气溶胶生成系数）分别对其O₃和SOA生成潜势贡献进行估算分析。结果表明，同行业排放的VOCs组成各不相同，存在地区差异；汽车行业单位O₃生成潜势最高，家具和喷涂行业基本持平；SOA生成潜势存在行业差异，印刷行业最小，汽车行业最大，两者相差约11倍；长三角、京津冀SOA污染严重，珠三角地区O₃污染较为严重。本研究建立了典型溶剂使用行业VOCs成分谱，估算了各行业、各地区的O₃及SOA生成潜势，可作为VOCs环境管理相关法规政策制定的重点依据。

VOCs are important precursors of ozone (O₃) and secondary organic aerosols (SOA).This investigation focuses on the source components of VOCs in typical solvent using industries,such as printing,furniture,shoemaking,coatings making,spraying,automobile,electronics,and so on in different areas of China.These industries' contribution to generation potential of ozone and SOA is estimated and analyzed by using MIR (maximum increment reaction activity coefficient) and FAC (aerosol generation coefficient).It is shown that the VOCs compositions discharged by the same industry are different,and there exist differences between areas;The potential of unit ozone generation in the automobile industry is the highest,and that in furniture and spraying industry stays essentially art the same level;The generation potential of SOA differs by industry,and that in the printing industry is the lowest,that in the automobile industry is the largest which is 11 times that in the printing industry.SOA pollution in the Yangtze River Delta and Beijing-Tianjin-Hebei regions is serious,and O₃ pollution in the Pearl River Delta region is relatively serious.VOCs composition spectrum in typical solvent using industries is established,and the generation potential of ozone and SOA in various industries and regions is estimated,which can be used as the key basis for the formulation of VOCs environmental management regulations and policies.
