Analysis of particulate matter emission characteristics and development of reduction management plan from different construction sites in Korea

Abstract

In recent years, the large range of air pollution and long time haze weather,bring inconvenience to people at the same time the work of life, also pose a great threat to people's health, the more frequent air pollution has sounded the alarm for us. So how to control air pollution, improve air quality and living environment has become a problem that must think, air pollution is not caused by a short duration of time, nor someone or some people caused by air pollution, and everybody's life. Specific reason, up from the source to control pollution to improve air quality. It is understood that the primary pollutant of air pollution is the total suspended particles, and a "significant contribution"to the total suspended particulate matter is the construction site dust. Therefore, to improve the city air quality, as a construction enterprise IT governance construction site dust is the most important task of the construction of civilization. A large amount of dust is produced in construction activities, which has a significant impact on the air quality of surrounding areas. In order to study the influencing factors of PM2.5 and PM10 concentration in the construction site, three representative construction sites were selected as the case for field measurement and analysis. In the experiment, the data of PM10 and PM2.5 (particles with aerodynamic diameter less than 10μm and 2.5μm) concentration, wind speed, relative humidity and temperature were collected by light scattering method for more than one hour one day. The results show that PM2.5 and PM10 are positive correlation, the concentration of earthwork is the highest, and that of bricklaying is the lowest. There is a positive correlation between PM10 and wind speed in earthwork. PM10 has a positive correlation with temperature and relative humidity at the structural engineering site. PM2.5、PM10 are negatively correlated with relative humidity, and PM10 is positively correlated with wind speed.According to different types of construction, the corresponding prevention and control measures are put forward.
