Road dust pollution prevention and control plan

Road dust is a composite dust source with multiple and complex emission sources, mainly from industrial coal smoke, construction sites, various dust powder storage yards, and sandstorms. It is affected by local urban winds, road cleanliness, urban vehicle speed and density, etc., and can generate secondary dust, resulting in high levels of dust particles in the atmospheric environment, which seriously affects the health of urban residents and the urban ecological environment. Currently, whether in urban or rural areas, the road network is well connected, resulting in a wide range and large amount of road dust pollution. Therefore, reducing road dust pollution is an important task for improving urban air quality.

The sources of road dust include:

The rapid increase in the number of motor vehicles has led to an accelerated rise in vehicle exhaust dust;

2. Low cleaning standards for urban roads and incomplete garbage collection and transportation systems;

3. Construction projects are not carried out in accordance with the requirements of civilized construction during the construction process, such as not setting up fences according to standards on the construction site, uncleanliness of waste disposal vehicles, carrying mud on the road, overloading, lack of hardening at the entrance and exit of the construction site, and lack of dedicated cleaning personnel;

4. The demolition project did not or did not timely sprinkle water to reduce dust during the construction process;

5. During the construction of municipal road projects, the exposed soil cannot be covered or cleaned up in a timely manner;

6. After planting trees for landscaping projects, the remaining soil cannot be cleared in a timely manner, and some green belts and tree pits are piled up with soil higher than the road surface;

7. Insufficient dust prevention measures in the yard, such as open-air loading, lack of coverage, lack of greenery, and failure to timely sprinkle water to reduce dust.

Problems in road dust control:

（1） Some roads have serious dust accumulation on both sides, especially during commuting hours, with high traffic flow and vehicles flying through the dust, which has a negative impact on the health of pedestrians and the image of the city.

（2） Some roads have low cleaning efficiency and cannot effectively reduce dust pollution sources.

（3） Part of the road surface is damaged and cannot be repaired in a timely manner, resulting in dust pollution caused by sand and gravel powder on the road surface.

（4） Construction site management is not strict, sixpercent100 (Surrounding fence around the construction site)percent100. Material stacking and coveringpercent100.

（5） Part of the green design is unreasonable. During rainy days, soil is washed onto the road surface, causing the road to become muddy. After sunny and dry weather, dust is formed again.

Therefore, in order to effectively prevent and control road dust pollution, continuously improve regional air quality, and comprehensively address road dustFANGSupervision and monitoring are essential to achieve real-time monitoring of dust pollution and scientific governance.

The Zhiyi Era Road Dust Monitoring Equipment is a standard monitoring terminal system of the grid based environmental monitoring system. It is an unmanned environmental collection system that integrates the collection, storage, transmission, and management of particulate matter and meteorological data, supporting all-weather monitoring24-hour online continuous monitoring, providing real-time air quality data for roads.
