Question

The smoke and dust particles are not the cause of air pollution.

Answer 1

Smoke and dust causes the air pollution as particulate matter. Smoke mixed with fog creates smog which is a major cause of pollution.

Complete step by step answer:
Particulate matter or particle pollution is a term that is used when solid and liquid create suspension in air. This suspension can be created in many sizes and shapes depending upon the size of different components as acid and bases and organic chemicals, soil and dust are present. We can broadly classify the particles into two main groups that are called as coarse particles and fine particles depending upon the diameter of particles.
The air we breathe contains various pollution causing particles. Some particles, such as dust, dirt, soot, or smoke, can be seen with the naked eye because they are larger in size while some particles are so small they can only be detected using an electron microscope of high power.
Particles with the diameter 10 micrometers or smaller cause the greatest problems. These smaller particles generally pass through the nose and throat and enter the lungs. These particles can affect the lungs and heart and cause serious health effects in individuals. Some people are more affected with this pollution such as people with heart or lung disease, people with diabetes, older adults and children. Larger particles are generally of less concern because they usually do not enter the lungs, but they can still cause irritation in the eyes, nose, and throat.

Note:
The source of this particle pollution varies depending on the source of particles that are emitted that is from construction sites, smoke and other particles present in the form of chemicals, gases and components released by automobiles.
