The Air Quality Index (AQI) provides a measure of how polluted the air is and indicates the potential health risks associated with exposure.
An AQI between 0 and 50 is considered good, while 51 to 100 falls in the moderate category. Levels between 101 and 200 are classified as poor, and 201 to 300 are considered unhealthy. AQI readings above 300 indicate severe pollution, while levels between 401 and 500 are hazardous.
Poor air quality can particularly affect children, elderly people and those with respiratory or heart conditions. However, prolonged exposure to high pollution levels can affect everyone. When the AQI is high, people should consider limiting outdoor activities, particularly strenuous exercise. Keeping windows closed during periods of heavy pollution and using an air purifier indoors can also help reduce exposure.
Tracking the AQI regularly can help residents make informed decisions about outdoor activities and take precautions when pollution levels rise.
