Air Pollution Concerns Not Changed by S-PLUS Flaw

摘要

A large body of scientific evidence has accumulated over the last decade showing that significant health effects occur from exposure to ambient par-ticulate matter (PM) concentrations near or below current federal standards that were presumably set to protect public health and the environment. This topic has recently been in the news because an analytical software issue surfaced that may modify the results of some epidemiological studies used by the U.S. Environmental Protection Agency (EPA) to evaluate PM standards. Unfortunately, a disproportionate amount of attention has been devoted to this concern that threatens to poison the public policy debate on PM air quality standards.
