In 2023, Beijing will be affected by dust for 30 days.

2023 is a year in which Beijing's air quality has been seriously affected by foreign dust in recent ten years.

In 2023, foreign dust frequently affected Beijing many times. According to the statistics of air quality monitoring results, 30 days of the year are directly affected by foreign dust, and 6 of the 8 days of heavy pollution are days of heavy pollution caused by foreign dust. Among them, a serious dust pollution process occurred in mid-April, resulting in 6-level heavy pollution for 2 days, 5-level heavy pollution for 2 days, and 4-level moderate pollution 1 day.

The peak concentration of PM 10 hour reached 1384 μ g/m3, which was the year in which the air quality was most affected by foreign dust in recent ten years, and the regional background concentration of particulate matter increased significantly. Faced with the irresistible influence of foreign dust, Beijing carries forward the spirit of "one microgram" and tries its best to overcome the "secondary pollution" caused by dust. Implement the "three dust * * * control" of construction, roads and bare land, and strengthen the "green" control of construction dust, road cleaning and ecological bare land.

Influence of dust:

1. Impact on the environment: Sandstorms will lead to soil erosion and desertification, making the land barren. Sandstorms can also block sunlight, affect the photosynthesis and growth of plants, and cause damage to the ecological environment.

2. Impact on transportation: Sandstorms may affect the safety of aviation, highway and railway transportation. Reduced visibility may lead to vehicle collision or accident. At the same time, sandstorms may also damage vehicles and infrastructure.

3. Impact on climate: Sandstorms may affect climate change. Particles in sandstorms may block sunlight and reduce heat absorption on the surface, which may lead to temperature change and humidity reduction. At the same time, sandstorms may also affect the distribution of precipitation and the formation and change of clouds.

4. Impact on the ecosystem: Sandstorms may affect the balance of the ecosystem. For example, sandstorms may block the migration channels of birds and animals and affect their survival and reproduction. At the same time, sandstorms may also affect the growth and reproduction of plants and affect the entire ecosystem.
