Title: Particulate Matter Is Not Killing Californians

Abstract:

There is now overwhelming epidemiologic evidence that particulate matter (PM), both fine particulate matter (PM2.5) and course particulate matter (PM10), is not related to total mortality in California. I will examine all the long-term PM epidemiologic cohort studies in California, and discuss the ways the findings from these studies have be used and/or ignored. I will discuss the limitations of these studies: lack of access to key databases; the ecological fallacy; failure to consider other pollutants; failure to satisfy causality criteria; and failure to consider other competing health risks. Also, ethical issues underlying much of PM2.5 epidemiology will be discussed. I will make a strong case that PM2.5 is not killing Californians and that there is not a scientific or public health basis for the many of the existing and proposed regulations designed to reduce PM levels in California.
