Causes and harm of haze weather

Reasons for the formation of haze weather:

1, the atmospheric pressure is low and the air does not flow.

2. The ground is dusty and the air humidity is low. People and vehicles on the ground stir up dust.

3. Automobile exhaust emission is also a factor of smog.

4. Secondary pollution produced by factories.

5. Pollutants such as carbon dioxide emitted by heating in winter.

Haze weather hazards:

First, the harm to the human body.

1. lung injury: the composition of smog is very complex, including hundreds of atmospheric chemical particles, which can make the condition acute or worse for patients with chronic respiratory diseases such as bronchial asthma.

2. Damage to heart and blood vessels: Smog will hinder normal blood circulation.

3. Hazy weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases.

Second, the harm to traffic and living environment

1. Affect traffic safety: the visibility is low in foggy days, which is easy to cause traffic jams.

2. Impact on living environment: Smog weather has an important impact on roads, railways, aviation, power supply systems and crop growth.

Prevention of smog

1, reduce going out

The elderly, children and people susceptible to respiratory diseases with weak resistance should try to reduce going out or outdoor activities, and wear masks to protect their bodies when going out to prevent pollutants from invading the lungs through the nose and mouth. After returning from going out, you should immediately wash your face and expose your skin.

Step 2 close the doors and windows

Because the pollutants in the air are difficult to dissipate in foggy days, doors and windows should be closed in foggy days to avoid outdoor fog entering the room to pollute the indoor air and induce acute respiratory and cardiovascular diseases.

Step 3 pay attention to your diet

Patients with chronic respiratory diseases, especially the elderly, should keep scientific life rules, avoid overwork and drink plenty of water. Pay attention to a light diet, eat less irritating food, eat more tofu, milk and other foods, and supplement vitamin D when necessary.
