Air is a core element for the sustenance of life. The cleaner the air, the better your health and well-being. However, various sources, especially anthropogenic, are posing a significant threat to air quality. In this article, we take a closer look at the situation in India, a country whose rapid expansion has seriously diminished air quality.
Pollution is the greatest risk to human life, more so in India than in any other country. Air Quality Index (AQI) is a numerical scale used to measure and report air quality of an area on a given day. Eight pollutants namely PM10, PM2.5, NO2, SO2, CO, O3, NH3, and Pb are the major parameters taken into consideration while deriving AQI of a region. Public health risks increase as the AQI rises. The following table shows the Air Quality Index (AQI) Categories and the Health impacts associated with each category.
