Older adults and children, and people with heart or lung disease are at greater risk from exposure to particle pollution. For example, children and older adults, people with lung disease, and people who are active outdoors (outdoor workers) are at greater risk from exposure to ozone. This is because they are more likely to be affected at lower air quality levels than everyone else. When AQI values are between 101 and 150, or code orange, members of sensitive groups may experience health effects. The higher the AQI value, the greater the level of air pollution and the greater the health concern. The Air Quality Index (AQI) is the official index for air quality across the United States. These factors can include life stages (children and older adults), specific health conditions (heart or lung disease), and increased likelihood of exposure from being active outdoors. The general public is not likely to be affected.Īir quality is acceptable however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.Īir quality is considered satisfactory, and air pollution poses little or no risk.ĪirCompare provides comparisons of air quality based on factors that have been shown to increase risk from air pollution. Members of sensitive groups may experience health effects. Health alert: everyone may experience more serious health effects.Įveryone may begin to experience health effects members of sensitive groups may experience more serious health effects. The entire population is more likely to be affected.
