While Delhi, neighbouring National Captial Region (NCR) and other North Indian states grapple with rising air pollution levels, the air quality levels in Mumbai, surrounding Thane and Navi Mumbai districts, have dropped to "unhealthy" levels on Sunday. Mumbaikars woke up to the city's skyline wrapped under a blanket of smog. The real-time overall air quality of the city at 10 am docked in at 181, higher than Gurugram's real-time AQI at 10 am of 162. The pollutant levels in Mumbai of PM 2.5 (particulate matter which can settle in the lungs and cause health ailments) was 114, which is considered very unhealthy.
According to Central Pollution Control Board's (CPCB) AQI bulletin for Saturday till 4 pm, Gurugram remained in a better position with an AQI of 78 which falls under 'satisfactory' category, while Mumbai docked in 190 which comes under 'moderate' category.
An AQI between 0-50 is considered "good", 51-100 "satisfactory", 101-200 "moderate", 201-300 "poor", 301-400 "very poor", and 401-500 "severe". Above 500 is "severe-plus or emergency" category.

Navi Mumbai experienced high levels of pollution with an overall AQI of 186 which falls under 'unhealthy' category. Thane docked an overall AQI of 107, which was relatively better than the rest of Mumbai.
"With the onset of winter, air quality has begun to deteriorate. As winter sets in, PM concentration in the air will rise as lower temperatures cause pollutants to get trapped closer to the earth’s surface, leading to an increase in the pollution levels," said SAFAR project director Gufran Beig told Fress Press Journal. System of Air Quality Weather Forecasting and Research's (SAFAR) data on Mumbai's air quality is currently unavailable their official website is currently shut.
Interestingly, Mumbai this year has recorded its 'cleanest Diwali air' in five years. As per data by Visual Visual on AQI world ranking, Mumbai figured in the top 10 most polluted Indian cities alongside Delhi and Kolkata.
