Heavily polluted air, however, can overwhelm the self-cleansing process, irritate the mucous membranes, or inhibit the movement of the cilia. Gases, such as ozone, bypass the self-defence mechanisms and reach the alveoli unhindered. Ozone is known to irritate and inflame the airways and possibly damages cells.
Asthma, hayfever, bronchitis, and even heart disease are just some of the many consequences of airborne impurities.

Breathing isn’t the only way that we are exposed to airborne pollutants and disease-causing microbes.
These substances are continually deposited in the soil as dry fallout or precipitation.
From the soil they enter the food chain and, ultimately, your body. Overall, your body absorbs more of a particular chemical via intake of food than through breathing.
It is the oxygen that our lungs are after. About 300 million tiny air sacs in the lung, the alveoli, help the blood absorb the oxygen and dispose of the waste, carbon dioxide.
