In order to study the impact of PM10 particle pollutant emissions on air at construction sites and its influencing factors, this study select six typical construction sites in Qingyuan City, and monitor PM10 particle emissions from sample sites in accordance with relevant national standards, and conduct econometric analysis. The following conclusion can be drawn: (1) there is indeed a slight PM10 pollution situation on some construction sites, but the main reason for PM10 concentration exceeds the limit is the external atmospheric environment rather than the construction site itself. (2) The PM10 pollutants generated by the dust at the construction site have a certain degree of impact on the air throughout the city. (3) Whether the upwind or downwind direction, the concentration value of the measuring point mainly depends on the air quality of the basic environment, and the correlation with the single meteorological factors is not obvious. (4) The dust generated by vehicles traveling has an important influence on the PM10 particle emission intensity at the construction site.
