Particulate matter is the main pollutant causing the deterioration of atmospheric air quality, and it is harmful to human health. In view of the current situation of increasingly serious air pollution and frequent smog weather, this experiment has conducted in-depth research on the influence of vehicle exhaust emission, one of the important sources of release of inhalable particulate matter, on the concentration of respirable particulate matter. The correlation is a theoretical basis for the source analysis of haze weather. Key words:Shenyang City;Road environment;Atmospheric particulate matter;Lon 已有研究表明，颗粒物粒子越小，比表面越大，越容易吸附有害物
