Abstract:
Tolbert (1) highlights issues that we also found to be complex as we interpreted the results of our analyses (2). We analyzed data from a 14-year interval over which particulate matter levels dropped substantially across the United States. We applied methods developed as part of the National Morbidity, Mortality, and Air Pollution Study for evaluating change in the short-term effect of particulate matter ≤10 μm in aerodynamic diameter over a period of increasingly stringent regulation that might have changed the chemical composition and toxicity of particulate matter. The decline in particulate matter concentrations over a span with uniformly collected particulate matter measurements and mortality provided an opportunity to assess whether the health of the public had benefited from the decline. Our work can be categorized as accountability assessment, that is, evaluating whether regulations have had an impact on harmful exposures and the occurrence of health …The perspectives, information and conclusions conveyed in research project abstracts, progress reports, final reports, journal abstracts and journal publications convey the viewpoints of the principal investigator and may not represent the views and policies of ORD and EPA. Conclusions drawn by the principal investigators have not been reviewed by the Agency.
