People who never smoked but who lived in areas with high level of air pollution are more likely to develop lung cancer than those who did not and those who are most likely to get it are women. Lung cancer among non smokers is 6th leading incident of cancer deaths in USA.
The study was conducted by Harvard School of Public Health, which says that air pollution standards must be kept as low as possible.
As stated earlier, the fine particles (PM 2.5) are responsible for creating irritation and inflammation in the lungs.
The study covered 26 years 180,000 samples in all states in USA. 1,100 died from lung cancer
In China, a study in 2009 attributed lung cancer to indoor air pollution, ie burning wooden stoves in homes

Air Pollution is a silent and deadly killer
Air pollution kills
The recent posts made show that air pollution is a silent and deadly assassin. From 2007, deaths attributed to air pollution grew from 2 million to 6 million as announced by WHO Department of Public Health and Environment Deaths in China grew from mere 700,000 to 1,200,000 just last year. And they have the highest concentration of PM 2.5, measured at 991 micrograms per cubic meter. (Considered safe max level is 25)
What is deadlier is the invisible particulate ie the PM 2.5 which 30x thinnner than human hair. It is deadlier because it can easily lodge itself into the lungs, or the blood cells and be carried elsewhere in the body. That is why in a study in England, spike in heart attacks/deaths has been traced to high level of PM 2.5 in air pollutants in England
No wonder, there are more deaths attributed to air pollution than to aids or malaria combined. WHO director for Public Health and Environment Maria Neira cited the death toll for AIDS, then considered as a scourge to be just l, 700,000 and malaria 660,000, in a Reuters interview (broadcast by GMA news) in 2010
