Abstract
In this issue of the Journal, Daniels et al. (1) report an analysis of the shape of the exposure-response relation between daily concentrations of particulate matter air pollution (PM) and mortality. They provide additional epidemiologic evidence of the absence of a population-based “no-effects” threshold level for PM within relevant ranges of exposure. Their results suggest that the PM-mortality exposure-response relation is near linear, with mortality risk occurring even at concentrations below current regulatory levels. This analysis is the latest of several important contributions to the literature on particuate matter and mortality by Samet, Zeger, and various colleagues.Keywords
