Air pollution is a major environmental and public health concern in India. The AQI India page on TodayHub provides a comprehensive overview of current air quality levels across major cities and regions, helping citizens stay informed and take necessary precautions.
Understanding Air Quality Index (AQI)
AQI, or Air Quality Index, is a standardized scale used to measure how polluted the air is and how it may affect human health. It considers pollutants such as PM2.5, PM10, ozone, nitrogen dioxide, sulphur dioxide, and carbon monoxide. A lower AQI value indicates cleaner air, while a higher value signifies greater pollution and potential health risks.
