The quality of the Air we breathe affects the quality of our health. Air quality has an impact on the health of our lungs and the entire respiratory system. In addition to oxygen, the air contains other substances such as pollutants, which can be harmful to health. The inhalation of those pollutants may have harmful effects on the lungs and other organs of the body. The respiratory system is particularly sensitive to air pollutants because it is made up of a mucous membrane covering its internal surface. The lungs are designed to absorb large amounts of air (400 million liters on average over a lifetime) in close contact with the bloodstream and facilitate the transport of oxygen.
The cells of the lung tissue can be damaged by air pollutants such as ozone, metals and free radicals. Ozone can cause damage to the alveoli - air sac in the lungs where exchange of oxygen and carbon dioxide is produced. More specifically, the airway tissues, which contain a large number of bio-activation enzymes, can transform organic pollutants into reactive metabolites, which can cause lung injuries, neuro-behavioral disorders, and cancers possibly including breast cancer.
