Particle Civics: Key Findings



Key Findings

  • Airborne particulate matter (PM) causes or contributes to the deaths
    of more Californians than car accidents, murder and AIDS combined. State
    health officials are proposing new air pollution rules that could save
    or extend more than 6,500 lives a year.


  • Considering health care costs and missed work days due to respiratory
    illnesses, the price tag for particulate pollution in California approaches
    $1 billion a year. Proposed new standards could save about half of that
    amount each year.


  • The proposed new standards would reduce the total number of deaths
    from all causes in California by about three percent a year. They would
    avert more than 300,000 asthma attacks and 2.8 million missed work days
    a year.


  • Only one California county is in full compliance with current state
    standards. Statewide, total PM emissions are on the rise, and the great
    majority of Californians are exposed to potentially harmful levels.
    Over 99 percent of Californians breathe air that violates current standards
    during at least part of the year.


  • Although agriculture is the largest industry in California and a major
    source of particulate pollution, especially in the San Joaquin Valley,
    agricultural activities are exempt from most air pollution rules.
