Abstract A building construction site located in Tianjin urban area was selected for study of fugitive dust emission from construction process. The ambient PM10, surface dust, meteorological condition and traffic flux were measured on site. Based on the fugitive dust model (FDM), PM10 emission factors were calculated by a Flux-FDM method developed in this study. Then by using nonlinear fitting, a quantitative mathematical model of PM10 emission factor for building construction was developed on the basis of measured data. By combination of the emission factor model and the Industrial Source Complex Model (ISC3), the impact of PM10 emissions from Tianjin construction sites on urban ambient air was simulated. The calculated average concentration of PM10 from construction sites was 20.3μg/m3 between November and December, 2003, accounting for 13.1% of ambient air PM10.
