California wildfires of 2008: Coarse and fine particulate matter toxicity

During the last week of June 2008, central and northern California experienced thousands of forest and brush fires, giving rise to a week of severe fire-related particulate air pollution throughout the region. California experienced PM10?2.5 (particulate matter with mass median aerodynamic diameter > 2.5 ?m to < 10 ?m; coarse ) and PM2.5 (particulate matter with mass median aerodynamic diameter < 2.5 ?m; fine) concentrations greatly in excess of the air quality standards and among the highest values reported at these stations since data have been collected.
