According to the air quality indicators defined by the Environmental Protection Agency of the Executive Yuan (hereinafter referred to as the Ministry of Environment), the monitoring data includes ozone (O3), fine suspended particulates (PM2.5), suspended particulates (PM10), carbon monoxide (CO), and sulfur dioxide in the air on that day. (SO2) and nitrogen dioxide (NO2) concentration and other values, and then the maximum value of each sub-indicator on that day is the air quality index value (AQI) of the measuring station on that day. Suspended particulates are one of the causes of poor air quality in Taiwan. 1. The main sources of suspended particulates include dust from vehicles, construction, motor vehicles, and open burning.
In recent years, the construction of public works has surged. Various civil construction projects require a large amount of fine sand. A large amount of sand is mined in Zhuoshui River. The dust generated during transportation affects the quality of life of residents. These are caused by dry and wet sedimentation. If the granular pollutants settled on the ground are not removed in time, they will be raised again with ground activities. Dust from vehicles is the most important type of pollution, which will again cause the deterioration of air quality. Through street cleaning operations, the load of road dust is reduced, the probability of road dust occurrence is reduced, and it has a specific effect on improving air quality.
