Industrial development and urbanization progress have been rapidly increasing in China, consequently accelerating infrastructure constructions, such as real estates and public facilities. Building construction dust has become one of the main sources of atmospheric particulate matter (PM) pollution in China. In this study, a typical building in Zhengzhou City was taken as an example, wherein the total suspended particle (TSP) and PM10 and PM2.5 indicators in the foundation excavation phase of the building construction were comprehensively monitored. The emission levels of both indicators were analyzed, and the periodic change laws of dust concentration and the correlations among TSP, PM10, and PM2.5 were quantitatively measured. Results indicate that the PM10 and PM2.5 concentrations at the monitoring points in the downwind direction of prevailing wind were higher than those in the upwind direction. TSP, PM10, and PM2.5 concentrations reached the maximum values at 10:00-12:00 in the morning of most days, and the TSP concentration was maintained at 250-500 μg/m3. Moreover, the coefficient of determination between TSP and PM10/PM2.5 was 0.8164/0.8376, signifying favorable correlations. The proposed management and control measures include perfecting the construction dust pollution control and management system, establishing the responsibility management mechanism of construction dust, realizing the comprehensive refined control of construction dust, promoting the innovation of building construction dust control technology, and improving the environmental consciousness for building construction dust control. These findings can serve as references for construction dust source pollutant emission control and as scientific decision-making bases for environmental researchers and managers in this field. |
