Thus, revealing the characteristics of construction dust is crucial for finding the way of reducing its effects. To fully uncover the characteristics of construction dust affecting surrounding areas, this study selected seven representative construction sites in Qingyuan city, China as empirical cases for field evaluation. In the experiment, the up-downwind method was adopted to monitor and collect TSP (total suspended particulate), PM 10 and PM 2.5 (particulate matter ≤10 μm and 2.5 μm in aerodynamic diameter, respectively) concentrations, meteorological data and construction activities of each site for 2 to 3 days and 18 h in a day. The results show that the average daily construction site makes the surrounding areas' concentration of TSP, PM 10 and PM 2.5 increase by 42.24%, 19.76% and 16.27%, respectively. The proportion of TSP, PM 10 and PM 2.5 in building construction dust is 1, 0.239 and 0.116, respectively. The large diameter particulate matter was the major constituent and the distance of its influence was limited. In addition, construction vehicles were one of the main influencing factors for building construction dust. However, building construction dust was not significantly correlated with any single meteorological factor when it did not change too much. Findings of this research can provide a valuable basis for reducing the impact of building construction dust on surrounding areas.||URI:||http://hdl.handle.net/10397/80858||EISSN:||2071-1050||DOI:||10.3390/su11071906||Rights:||© 2019 by the authors.
