A review of evidence regarding whether ambient air pollution exposure is a risk factor for cancer in 2007 found solid data to conclude that long-term exposure to (fine particulates) increases the overall risk of non-accidental mortality by 6% per a 10 microg/m 3 increase. Exposure to was also associated with an increased risk of mortality from lung cancer (range: 15% to 21% per 10 microg/m 3 increase) and total cardiovascular mortality (range: 12% to 14% per a 10 microg/m 3 increase). The review further noted that living close to busy traffic appears to be associated with elevated risks of these three outcomes --- increase in lung cancer deaths, cardiovascular deaths, and overall non-accidental deaths. The reviewers also found suggestive evidence that exposure to is positively associated with mortality from coronary heart diseases and exposure to SO 2 increases mortality from lung cancer, but the data was insufficient to provide solid conclusions. [63] Another investigation showed that higher activity level increases deposition fraction of aerosol particles in human lung and recommended avoiding heavy activities like running in outdoor space at polluted areas.
