Harm of sandstorm

Sandstorm hazards mainly include environmental pollution, production and life affected, loss of life and property, traffic safety and human health.

1, environmental pollution?

When sandstorms occur, dust and floating dust carried by strong winds are everywhere, and the number of people passing through areas with air turbidity, choking nose and eyes, respiratory tract and other diseases increases.

2. Is production and life affected?

A lot of dust carried by sandstorm weather blocked the sun, and the weather was gloomy, which led to the decrease of solar radiation. A few hours to ten hours of poor visibility can easily make people feel depressed and reduce the efficiency of work and study. In light cases, a large number of livestock can be infected with respiratory and gastrointestinal diseases, and in severe cases, a large number of "spring-deficient" livestock will die, and fertile soil, seeds and seedlings in farmland will be scraped away.

Sandstorm will also aggravate the wind erosion and desertification of the surface soil, cover thick dust on the leaves of plants, affect normal photosynthesis and cause crop yield reduction. Sandstorms also caused the temperature to drop sharply. The sky is like a parasol, and the ground becomes dark and cold in the shadow.

3. Loss of life and property?

1On May 5, 1993, a serious sandstorm occurred in Jinchang, Wuwei, Minqin and Baiyin, Gansu Province, which affected 2,535,500 mu of farmland, lost 42,800 trees, caused a direct economic loss of 236 million yuan, killed 85 people and seriously injured 153 people. On April 12, 2000, serious sandstorms occurred in Yongchang, Jinchang, Wuwei and Minqin. According to incomplete statistics, the direct economic losses in Jinchang and Wuwei alone amounted to15.34 million yuan. ?

4. Affect traffic safety?

Sandstorms that affect traffic safety (traffic accidents such as airplanes, trains and cars). ) often affect traffic safety, resulting in aircraft can not take off or land normally, cars, train cars break, stop or derail. ?

5. Harm human health?

When people are exposed to dusty weather, dust containing various toxic chemicals and bacteria can enter the mouth, nose, eyes and ears through layers of protection. If the dust containing a lot of harmful substances is not cleaned in time, it will cause damage to these organs or bacteria will take these organs as invasion points, causing various diseases. High dust concentration in the atmosphere is easy to cause respiratory diseases. For example, sandstorm pneumoconiosis is an endemic disease caused by severe atmospheric dust in arid and semi-arid environments.
