Air Quality
Air quality indicators measure levels of environmental contaminants that present human health risks. Air pollutants contribute to numerous health and visual impairments such as asthma, heart disease, and regional haze. Ozone (O3), carbon monoxide (CO), and particulate matter (PM10--particles between 2.5 and 10 microns in size) are three of the six common air pollutants identified by the EPA as being critical to assessing environmental health of a place. Phoenix has been identified as an area that is out of compliance with air quality standards for CO, O3, and PM10.
