Delhi’s air quality is a major concern for residents and visitors alike. Understanding the Air Quality Index (AQI) is crucial for protecting your health. This article provides information on what AQI is and how to find today’s AQI for Delhi.
Understanding the Air Quality Index (AQI)
The Air Quality Index (AQI) is a numerical scale used to communicate the level of air pollution in a specific location. It ranges from 0 to 500, with higher values indicating worse air quality and greater health risks. The AQI is based on measurements of various pollutants, including:
- PM2.5: Fine particulate matter with a diameter of 2.5 micrometers or less, which can penetrate deep into the lungs and bloodstream.
- PM10: Larger particulate matter with a diameter of 10 micrometers or less.
- Ozone (O3): A gas that can irritate the respiratory system.
- Sulfur Dioxide (SO2): A gas produced from burning fossil fuels, contributing to respiratory problems.
- Nitrogen Dioxide (NO2): A reddish-brown gas that can irritate the lungs and contribute to smog.
- Carbon Monoxide (CO): A colorless, odorless gas that can be harmful at high concentrations.
Each pollutant is assigned a sub-index, and the highest sub-index determines the overall AQI for a given area.
How to Find Delhi’s AQI Today
Several resources provide real-time and historical AQI data for Delhi:
- Government Agencies: The Central Pollution Control Board (CPCB) and the Delhi Pollution Control Committee (DPCC) are the primary sources of AQI data for India. Their websites offer detailed information and often include interactive maps.
