Abstract
The 2023 air quality assessment was conducted at five key industrial sites (Song Than II Industrial Zone, Thuan Giao Industrial Cluster, Thuong Tan Quarry, My Phuoc II Industrial Zone, Bau Bang Industrial Zone) in Binh Duong province, aiming to evaluate the potential air pollution in surrounding areas and the health impacts on workers in nearby residential areas. The survey results for several air pollution parameters, including NO2, total suspended particulates (TSP), and noise levels from the 2023 monitoring data provided by the Center for Environmental Monitoring and Technical Resources in Binh Duong province, indicated that at the Thuong Tan Quarry, TSP concentrations ranged from 26.0 to 374.8µg/Nm3, exceeding the standard by 74.8µg/Nm3 according to QCVN 05:2023/BTNMT. Noise levels at the quarry ranged from 59.7 to 72.1 dB(A), exceeding the standard by 2.1 dB(A) according to QCVN 26:2010/BTNMT. Additionally, air quality monitoring results at various industrial sites in Binh Duong indicated that the annual average levels of air pollutants at these industrial zones met the permissible limits set by QCVN 05:2023/BTNMT and QCVN 26:2010/BTNMT, with TPS concentrations ranging from 11.5 to 374.8µg/Nm3, noise levels from 57 to 72.1 dB(A), and NO2 concentrations from 18 to 85.5µg/Nm3. According to the 2023 air quality results, air quality in industrial zones has relatively improved compared to previous years, although some monitoring points still exceed the regulatory limits. Due to the different nature of production activities at the quarry compared to other industrial sites, more dust and noise are generated, necessitating management measures for production equipment and technological changes.
