Why does smog happen?

Answer 1

Smog is a result of a combination of photochemical reactions which involve:

1. Ground-Level Ozone (made from VOCs)

2. Nitrogen oxides.

3. Peroxyacytyl Nitrate (a dangerous gas).

4. Dirt and matter (stuff that "clogs" the air: dust and burnt matter (smoke))

Smog is linked to heavy traffic, high temperatures, and little wind, NOT CO2, a common misconception.

Answer 2

Smog is a form of air pollution produced by the photochemical reaction of sunlight with hydrocarbons and nitrogen oxides that have been released into the atmosphere, especially by automotive emissions

Answer 3

Smog is caused by many factors. The smog that enters the atmosphere consists of over 100 chemicals, many coming from different sources. Particulates present in smog include carbon monoxide, dirt, soot, dust, and ozone. To really create the smog effect, sunlight, hydrocarbons, and nitrogen oxides have to mix together. Major producers of smog include automobiles, fires, waste treatment, oil production, industrial solvents, paints, and coatings. Car engines, especially diesel engines, as well as gas stations that allow gas to be leaked out are huge contributors to the smog problem. Gas vapor that gets away from gas pumps contributes to the hydrocarbons needed to form smog. Diesel engines emit particles of soot that enter the atmosphere. Today, the smog problems created by cars are becoming increasingly severe. As gas prices decline, consumers are buying cars that use more gas, and hence pollute the atmosphere to a greater extent.

Answer 4

Well, pollution is produced mostly by vehicles in Madrid, Spain.

Answer 5

Smog is a mixture of smoke and fog.

Answer 6

car exhaustion
