Occupational lung diseases

Occupational lung diseases are lung problems that are made worse in certain work environments. They are caused by long-term exposure to certain irritants that are breathed into the lungs. These lung diseases may have lasting effects, even after the exposure ends.
Particles in the air from many sources, such as factories, smokestacks, exhaust, fires, mining, construction, and agriculture , cause these lung problems. The smaller the particles are, the more damage they can do to the lungs. Smaller particles are easily inhaled deep into the lungs. There, they are absorbed into the body instead of being coughed out:

This condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack, the lining of the passages swell causing the airways to narrow and reducing the flow of air in and out of the lungs. Causes of childhood asthma: Researchers continue to learn what causes asthma. It is not entirely understood. The following things play a part: Genetics:  Asthma runs in families.
