The Lung


Updated Dec. 15, 2108

* Air pollution permanently inhibits lung growth in children. In fact prenatal exposure can reduce fetal lung development, impairing lung function in childhood and permanently reducing the number of alveoli (air sacs) in the lungs.

* Brief exposure to ozone and particulate matter reduce lung function even in young healthy adults and the reduction can last for a week after the pollution exposure is over.

* Air pollution causes lung cancer.

* Long term ozone exposure causes an increase in overall mortality in addition to that from particulate matter. Most of the mortality is respiratory.

* Air pollution exacerbates virtually all pulmonary diseases and likely plays a causative role in reactive airways disease, and some cases of COPD.

* Air pollution is associated with increased rates of serious lower respiratory infections, and hospitalization and death from most respiratory diseases from neonates to the elderly.

* The correlation between the above health outcomes and ozone are still found at concentrations between one half and one third the current EPA  National Ambient Air Quality Standards.

*Early life exposure to pesticides is associated with decreased lung function

*Air pollution causes DNA damage and cell death to lung cells and erodes the nasal mucosa.
