What environmental conditions might cause damage to the alveolar sacs, and what would be the consequences of that damage?

The environmental conditions that can cause damage to the alveolar sacs is dust storms, air pollution such as smoke and heavy smog. They can cause permanent or temporary damage to the alveolar sacs ranging from buildup of fluid in the sacs to accumulation of particles which cause coughing and prevention of air supply into the lungs. Long term exposure could also lead to cancer.

Following are the major environmental conditions that might cause a damage to the alveolar sacs:

1. Air pollution

2. Dust storms

3. Smog

4. Smoke

The aforementioned conditions can cause temporary or permanent damage to alveolar sacs. Damages may include: building up fluid in the sacs and accumulation of dust particles in the sacs. The consequences of that may include coughing or preventation of oxygen (air supply) into the lungs.
