Understanding Local Air Quality Index (AQI): What It Means and How to Protect Your Health

Introduction

The Air Quality Index (AQI) is a standardized system used to communicate daily air quality levels to the public. It provides information on how clean or polluted the air is and the associated health risks. Understanding the AQI is crucial for making informed decisions to protect your health, especially for sensitive groups such as children, the elderly, and individuals with respiratory or cardiovascular conditions.

What Is the Air Quality Index (AQI)?

The AQI is a numerical scale ranging from 0 to 500, where higher values indicate higher levels of air pollution and greater health risks. The index is divided into six categories:

  • 0–50 (Good): Air quality is satisfactory, posing little or no risk.
  • 51–100 (Moderate): Air quality is acceptable; however, there may be a moderate health concern for a small number of individuals sensitive to air pollution.
  • 101–150 (Unhealthy for Sensitive Groups): Sensitive individuals may experience health effects; the general public is less likely to be affected.
  • 151–200 (Unhealthy): Everyone may begin to experience health effects; sensitive groups may experience more serious effects.
