Air Quality Index
The Air Quality Index (AQI) is a numerical scale used to communicate the quality of air in a specific area. It measures the concentration of pollutants, such as particulate matter, ozone, carbon monoxide, and sulfur dioxide. The AQI ranges from 0 to 500, with lower values indicating better air quality and higher values indicating worse air quality.
The AQI is divided into categories that represent different levels of health concern. For example, an AQI value of 0-50 is considered "Good," while a value of 301-500 is classified as "Hazardous." This system helps individuals understand the potential health effects of air pollution and take necessary precautions.
