When the AQI is in the "Good" range (0-50), air quality is considered satisfactory, and air pollution poses little or no risk. You can generally carry out your usual activities without concern. In the "Moderate" range (51-100), air quality is acceptable; however, some pollutants may pose a moderate health concern for a very small number of people who are unusually sensitive to air pollution. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. The "Unhealthy for Sensitive Groups" range (101-150) means that members of sensitive groups may experience health effects. This includes children, the elderly, and individuals with respiratory or heart disease. The general public is not likely to be affected. People in these sensitive groups should reduce prolonged or heavy outdoor exertion. When the AQI reaches the "Unhealthy" range (151-200), everyone may begin to experience health effects; members of sensitive groups may experience more serious effects. It's advisable to reduce prolonged or heavy outdoor exertion during these times. In the "Very Unhealthy" range (201-300), the risk of health effects increases for everyone, especially sensitive groups. It's recommended to avoid all physical activity outdoors. The "Hazardous" range (301-500) signals a health emergency. Everyone is likely to experience health effects, and it's crucial to avoid all outdoor activities. In addition to the AQI, air quality forecasts may provide information about specific pollutants, such as PM2.5 or ozone. This information can help you understand which pollutants are driving the overall AQI and take more targeted precautions. By regularly checking air quality forecasts and understanding the AQI, you can make informed decisions about your daily activities and protect your health.
