Release of Fine Particle Pollution Health Report

Sacramento - Approximately 9,000 people in California are estimated to die prematurely each year as a result of exposure to fine particle pollution, according to a report issued today by the California Air Resources Board.

The report "Estimate of Premature Deaths Associated with Fine Particle Pollution in California Using the United States Environmental Protection Agency Methodology" was released on August 31, 2010.

This report estimates the premature deaths associated with long-term public exposure to fine particulate matter air pollution (PM2.5) in California. It uses the methodology described in the United States Environmental Protection Agency's (U.S. EPA) recently released "Quantitative Health Risk Assessment for Particulate Matter", supported by the finding in U.S. EPA's 2009 Integrated Science Assessment that the scientific evidence shows a causal connection between premature death and exposure to PM2.5. These two U.S. EPA reports were prepared as part of U.S.

EPA's periodic review of the National Ambient Air Quality Standards (NAAQS) for particulate matter and peer reviewed through a public process by the Clean Air Scientific Advisory Committee Particulate Matter Review Panel, an independent peer review body of national scientists. The U.S. EPA health risk assessment estimated premature deaths associated with PM2.5 nationwide, and in 15 urban areas including Los Angeles and Fresno. This report applies the U.S. EPA methodology to California statewide using air pollution data from 90 monitoring sites.
