'Thick smog, reduced visibility': Mumbai's air quality worse than Delhi

The air quality in Mumbai on October 18 was recorded in the ‘very poor’ category with an air quality index of 301. A thick layer of smog engulfed the Chhatrapati Shivaji Terminus (CST) and Marine Drive area as the air quality dropped drastically. Earlier on October 17, the air quality in Mumbai was recorded in the ‘moderate’ category. The Air Quality Index is a tool for effective communication of air quality status to people in terms that are easy to understand. There are six AQI categories, namely Good + Satisfactory, Moderately polluted, Poor, Very Poor, and Severe. Each of these categories is decided based on ambient concentration values of air pollutants and their likely health impacts (known as health breakpoints).According to the AQI scale, the air quality check between 0 and 50 are considered "good", 51 and 100 are “satisfactory”, 101 and 200 are “moderate”, 201 and 300 are “poor”, 301 and 400 are “very poor”, and 401 and 450 are “severe” and “severe+” when AQI exceeds 450.Subscribe to The Times of India's YouTube channel: http://goo.gl/WgIatuFor daily news & updates and exclusive stories, follow the Times of IndiaFacebook:https://www.facebook.com/TimesofIndiaInstagram:https://www.instagram.com/timesofindia/Download the app: http://toi.in/3SLUCa80Follow the TOI WhatsApp channel: https://bit.ly/3RYl0J9Follow TOI+ for well-researched and in-depth news and analysisFacebook:https://www.facebook.com/timesofindiaplusTwitter:https://twitter.com/TOIPlusInstagram:https://www.instagram.com/toi_plus/
