Long-Term Air Pollution Exposure Tied to Lung Cancer, Cardiopulmonary Mortality

NEW YORK (Reuters Health) Mar 06 – A report in the March 6th issue of The Journal of the American Medical Association confirms the link between combustion-related fine particulate air pollution and cardiopulmonary mortality, and for the first time shows a significant association with lung cancer mortality.
Dr. C. Arden Pope III, from Brigham Young University, Provo, Utah, and associates used data from the American Cancer Society's Cancer Prevention Study II to measure the effect on mortality from combustion-related fine particle air pollution in metropolitan areas across the US.

The Cancer Prevention Study II included about 1.2 million adults recruited in 1982. Dr. Pope's team linked risk factors for about 500,000 of these adults with air pollution data and vital status and cause of death data through December 31, 1998.

The researchers found that fine particulate and sulfur oxide-related pollution were associated with all-cause, lung cancer, and cardiopulmonary mortality. For each 10- g/m increase in fine article air pollution, all-cause mortality increased 4%, lung cancer mortality increased 8%, and cardiopulmonary mortality increased by 6%, Dr. Pope's group notes.
