While construction sites have resumed work in New Delhi after the air pollution levels have finally cleared, Mumbai recorded “very poor” levels of air quality on Tuesday. The city was covered with a layer of smoke through the day.
SAFAR (System of Air Quality Weather Forecasting and Research) has shared that they recorded an increase in AQI levels increase from 280 during the day to 291 by the evening, both come under the ‘poor’ category. It has advised people suffering from heart or lung diseases, elderly and small children, to avoid any form of exertion. Delhi recorded ‘very poor’ air quality from the continuous “severe” levels last week.
The agency has also suggested that the pollution levels in Mumbai are expected to get worse from Wednesday.
“While weather factors such as temperature and moisture were normal, pollution levels increased because wind speed was very low on Tuesday. If this phenomenon tends to happen then the pollutants are not easily dispersed from the city’s air,” Biswajit Mukhopadhyay, additional director general, India Meteorological Department told HT.
He added the source of the pollutants is a ridge line (high-pressure area) 300km north of Mumbai that is allowing pollutants to move towards the city. “While this condition is common during this time of the year, additional sources such as vehicular pollution, construction dust and open burning have increased pollution.”
Seven of 10 locations on Wednesday recorded ‘very poor’ AQI levels, with Andheri being the most polluted at 350.
Delhi is breathing slightly better this week with pollution levels finally falling.

The Delhi Pollution Control Committee (DPCC) informed a meeting last week comprising Delhi’s Lt Governor Najeeb Jung that it recorded a one-third fall in PM 10 levels in two weeks and one-fourth in PM 2.5 levels in the same period.
The air quality index on Monday had improved to 311, the best since October 26 when the index was at 219. It, however, continued to be in the unhealthy zone.
While the situation in Mumbai is worrying, the fight for breathing easy is not over for Delhi which is still recording a higher pollution level compared to Mumbai.
