Understanding Air Quality Index (AQI)

The Air Quality Index (AQI) serves as a standardized tool to communicate the quality of air in a specific location. It synthesizes complex environmental data regarding various pollutants into a single value, making it easier for the public to understand air safety. The AQI is calculated based on the concentrations of several harmful pollutants, including particulate matter (PM2.5 and PM10), ground-level ozone (O3), carbon monoxide (CO), sulfur dioxide (SO2), and nitrogen dioxide (NO2). Each of these pollutants is assigned a numerical value that corresponds to predetermined health standards.

The AQI scale typically ranges from 0 to 500, categorized into different levels that indicate potential health effects. Values of 0-50 fall within the “Good” range, presenting little or no risk. As the AQI increases, it enters the “Moderate” (51-100), “Unhealthy for Sensitive Groups” (101-150), “Unhealthy” (151-200), and “Very Unhealthy” (201-300) classifications. An AQI above 300 is categorized as “Hazardous,” warning the general public to limit outdoor activity. Understanding these classifications is crucial for individuals, particularly vulnerable populations such as children, elderly individuals, or those with pre-existing health conditions.

Health implications are associated with various AQI readings. For instance, a moderate AQI can lead to respiratory issues in sensitive individuals, while high levels of pollution (AQI above 150) may affect everyone, increasing risks for heart and lung diseases. Therefore, monitoring air quality is essential for public health and safety, especially in regions like Lahore, known for fluctuating air quality. This alert system not only enhances public awareness but also enables individuals to take proactive measures to reduce their exposure to harmful air pollutants.
