Abstract
Title continued - in Anchorage, Alaska. In Anchorage, Alaska, particulates with aerodynamic diameter /=34 ug/m3. A significant 18.1% increase (RR: 1.181, 95% CI: 1.010-1.381) in the rate of quick-relief medication prescriptions occurred during days with PM10 of 34-60 ug/m3, and a 28.8% increase (RR: 1.288, 95% CI: 1.026-1.619) occurred during days with PM10 >/=61 ug/m3. Similar results for outpatient asthma visits and quick-relief medication occurred in weekly models. There were no significant associations with PM2.5 in either daily or weekly models. These subtle but statistically significant associations suggest that non-industrial, geologic sources of PM10 may have measurable health effects at levels below current national standards.
