Air Pollution is now officially a carcinogen, and there are no caveats about the new clarification. - CNN

A new study led by researchers at Harvard School of Public Health (HSPH) has found an association between reductions in fine particulate matter and improved life expectancy in 545 Counties in the U.S. from 2000 to 2007.  It is the largest study to date to find beneficial effects to public health of continuing to reduce air pollution levels in the U.S.    - Harvard School of Public Heath

This study focused on levels of fine particulate mtter, known as PM2.5 (indicating that the particles have a diameter of 2.5 micrometers or less).  It is well established that both acute and chronic exposure to PM2.5 is associated with a higher risk of cardiovascular and lung disease and death.  - Natural News

Studies have also shown that reductions in air pollution are associated with reductions in adverse health effects and improved life expectancy.  - Harvard School of Public Health

Modeling the situation for the United States, the study suggests that if the average PM2.5 were reduced by 3.9 micrograms per cubic meter, nearly 8,000 heart-failure hospitalizations would be averted each year and the country would save a third of a billion dollars annually. - Fox News

Controlling for socioeconomic status, smoking prevalence, and demograrphic characteristics, the results showed that a disease of 10 micrograms per cubic meter in the concentration of PM2.5 during the period of 2000 to 2007 was associated with an average increase in life expectancy of .35 years in 545 U.S. counties.  - Harvard Scholl of Public Heath
