At highest risk from particle pollution are people with heart or lung disease, older adults (possibly because they may have undiagnosed heart or lung disease), and children whose lungs are still developing and who are more active outdoors as well as children suffering from asthma. Particle pollution data are generated using monitoring techniques that approximate the Federal Reference Method. The data are published as soon as practical after the end of each hour and as such are not fully validated. Therefore, data are only approved for the expressed purpose of reporting and forecasting the Air Quality.
