U.S. EPA's health-based national air quality standards for PM-10 are 50 µg/m3 (measured as an annual average) and 150 µg/m3 (measured as a daily average) (49). The U.S. EPA has recently proposed a new standard for particles less than 2.5 microns in diameter, 15 µg/m3 (measured as an annual average) and 65 µg/m3 (measured as a daily average) (50).
