What is smog?
Smog is a combination of smoke and fog, usually associated with densely populated industrial areas. The word smog is a combination of the English words smoke and fog.
Such air pollution consists of nitrogen oxides, sulfur oxides, ozone, smoke, or less visible pollutants such as carbon monoxide, chlorofluorocarbons, etc.
How is smog formed?
When the atmosphere is polluted or the gases that make up smog are released into the air, sunlight, and its heat react with these gases and compounds in the atmosphere to form smog. The main reason for this is air pollution. This is usually the result of high traffic, high temperatures, sunlight, and stagnant air, i.e. in winter when the wind speed is low it helps the smoke and fog to settle in places that form smog. is formed when the emission rate of pollutants near the ground increases.
The main causes of smog are emissions from petrol and diesel vehicles, industrial plants and activities, crop burning (as the Meteorological Department says), or heat generated by human activities.
What to do to prevent smog?
When smog spreads, one should avoid visiting the affected areas, but if it covers the entire city, prefer to stay indoors and keep the windows closed.
Use a face mask when going outside; if wearing contact lenses, prefer glasses.
Avoid exercising during smog, especially during the middle of the day, when ground-level ozone levels are highest.
If you suffer from asthma, keep this inhaler with you at all times, if the condition worsens suddenly, consult a doctor.
