Extended Follow-Up and Spatial Analysis of the American Cancer Society Study Linking Particulate Air Pollution and Mortality

Research Report 140,
2009

This report describes a recent analysis of the original ACS cohort, a large ongoing prospective study of mortality in adults that started in 1982 and has played a central role in the setting of National Ambient Air Quality Standards for fine particulate matter pollution in the U.S. as well as assessments of benefits from PM reduction worldwide. The new study describes for the first time work by Dr. Daniel Krewski and colleagues to increase the follow-up period to 18 years (1982 to 2000) and extend the range of analyses to include innovative refinements of statistical methods and incorporate sophisticated control of bias and confounding.
