What is AQI?

AQI stands for Air Quality Index. It is a number used to show how clean or polluted the air is in a particular area. The AQI ranges from 0 to 500, with higher numbers meaning more pollution. It helps people understand the health risks from air pollution, like breathing problems, especially for sensitive groups.

Key Pollutants Measured by AQI

The AQI is calculated based on the levels of various air pollutants, including:

  • Particulate Matter (PM): Tiny particles in the air that come from sources such as vehicle exhaust and industrial emissions.
  • Ground-Level Ozone: A harmful gas formed when pollutants react with sunlight.
  • Carbon Monoxide: A colorless, odorless gas produced by incomplete combustion.
  • Nitrogen Dioxide: A reddish-brown gas emitted by the burning of fossil fuels.
  • Sulfur Dioxide: A colorless gas that comes from burning fossil fuels, especially coal.
