Effect of Air Pollution Control on Mortality and Hospital Admissions in Ireland

This report revisits an earlier study of the air pollution and health impacts of a coal ban in Dublin, Ireland, and then extends the analysis to coal bans in 11 additional Irish cities. Dr. Douglas W. Dockery of the Harvard School of Public Health and colleagues evaluated changes in black smoke and sulfur dioxide concentrations for the 5 years before and after the coal bans and examined how those changes related to mortality and hospitalization rates in the counties affected by the bans, as compared with other counties where coal bans were not implemented. They also included in their analysis other trends in health and social factors that were occurring at the same time.
