Mumbai’s air quality improved from ‘poor’ to ‘moderate’ – due to recent unseasonal rains, which settled pollutants.
However, experts expect that to change once the skies clear.
Mumbai recorded an air quality index (AQI) of 166 (moderate) on Saturday, which was lower than most days in the last four months.
The recent rains helped clear the air by washing away most of the common air pollutants through a process called wet deposition.
For reference, an AQI between 0 and 50 is considered ‘good’, 51 to 100 ‘satisfactory’, 101 to 200 ‘moderate’, 201 to 300 ‘poor’, 301 to 400 ‘very poor’ and 401 ‘very poor’. To 500 is believed to be between. ‘Serious’. The air quality in Mumbai is being recorded from ‘poor’ to ‘very poor’, some days worse than Delhi and other major cities.
Experts blame vehicular pollution and construction activities for the deteriorating air quality.
Thackeray wrote a letter to Bhupendra Yadav
Shiv Sena MLA Aditya Thackeray on Saturday wrote a letter to Union Minister Bhupendra Yadav on the issue of poor air quality in Mumbai and rising air pollution across Maharashtra.
“I have written to Union Minister Bhupinder Yadav-ji about Maharashtra’s worsening air pollution crisis, also focusing on Mumbai’s AQI. The absence of a full-time environment minister in the state’s illegitimate government and lack of sensitivity to public issues has only deepened this crisis as no action has been taken on the ground,” he wrote in a tweet.
“Climate change has had a severe impact on the city’s weather patterns, with winds changing speed and direction, and polluted air being retained within the city instead of blowing towards the coast. I request you to direct the concerned authorities to install mobile sensors in the entire city, as the existing sensors do not cover the entire city. This will provide more insight to address the problem of air quality and help in reconciling the data authenticity of the AQI currently measured,” the letter said.
