Understanding Air Quality Index (AQI)
The Air Quality Index (AQI) is a numerical scale used to communicate how polluted the air currently is or how polluted it is forecast to become. It transforms complex air quality data from multiple pollutants into a single number and color-coded category that is easy to understand.
AQI values range from 0 to 500, with higher values indicating worse air quality. The index is divided into six categories: Excellent (0-50), Fair (51-100), Poor (101-150), Unhealthy (151-200), Very Unhealthy (201-300), and Dangerous (301-500).
AQI Categories & Health Impacts
Poor air quality can have serious health consequences, especially for vulnerable groups like children, elderly people, and those with pre-existing respiratory or cardiovascular conditions. The health impacts vary significantly depending on the AQI category.
Good
AQI: 0-50
Air quality is satisfactory. No health impacts expected for the general population.
Satisfactory
AQI: 51-100
Air quality is acceptable. Some pollutants may affect very sensitive individuals.
Moderate
AQI: 101-200
Members of sensitive groups may experience health effects. General public less likely to be affected.
Poor
AQI: 201-300
Everyone may begin to experience health effects. Sensitive groups should avoid prolonged exposure.
Very Poor
AQI: 301-400
Health alert: everyone may experience more serious health effects. Avoid outdoor activities.
Severe
AQI: 401 & above
Emergency conditions: any exposure to air, even for a few minutes, can lead to serious health effects on everybody. Avoid outdoor activities.
Key Air Quality Parameters
Air quality is measured by monitoring various pollutants that affect human health and the environment. These key parameters are tracked to assess air pollution levels and their potential impacts on respiratory health, cardiovascular systems, and overall well-being.
Particulate Matter (PM2.5)
Fine Particulate Matter are inhalable pollutant particles with a diameter less than 2.5 micrometers that can enter the lungs and bloodstream, resulting in serious health issues. The most severe impacts are on the lungs and heart. Exposure can result in coughing or difficulty breathing, aggravated asthma, and the development of chronic respiratory disease.
Particulate Matter (PM10)
Particulate Matter are inhalable pollutant particles with a diameter less than 10 micrometers. Particles that are larger than 2.5 micrometers can be deposited in airways, resulting in health issues. Exposure can result in eye and throat irritation, coughing or difficulty breathing, and aggravated asthma. More frequent and excessive exposure can result in more serious health effects.
Nitrogen Dioxide (NO₂)
Breathing in high levels of Nitrogen Dioxide increases the risk of respiratory problems. Coughing and difficulty breathing are common and more serious health issues such as respiratory infections can occur with longer exposure.
Sulfur Dioxide (SO₂)
Exposure to Sulphur Dioxide can lead to throat and eye irritation and aggravate asthma as well as chronic bronchitis.
Ozone (O₃)
A reactive gas that can damage lung tissue and aggravate respiratory conditions. Ground-level ozone is formed when pollutants react in sunlight.
Carbon Monoxide (CO)
A colorless, odorless gas produced by incomplete combustion of fossil fuels. High concentrations can cause headaches, dizziness, and in extreme cases, death by preventing oxygen from reaching vital organs.
