Extended follow-up and spatial analysis of the American Cancer Society study linking particulate air pollution and mortality

This study presents a research project funded by the Health Effects Institute and conducted by Dr. Daniel Krewski of the McLaughlin Centre for Population Health Risk Assessment, University of Ottawa, Ontario, Canada, and his colleagues. It looks at the American Cancer Society Cancer Prevention Study II (CPS-II), a large ongoing prospective study of mortality in adults initiated in 1982. This study was one of two U.S. cohort studies central to the 1997 debate on the National Ambient Air Quality Standard (NAAQS) for fine particulate air pollution in the United States.
