In a bid to mitigate the city’s air pollution woes, the BMC, as part of its 2023 budget, announced the installation of two smog towers each in seven zones in Mumbai. Experts and health professionals, however, have termed these towers a waste of taxpayers’ money. Clean Air Mumbai, a network of citizens and Civil Society Organisations (CSOs), organised a plenary discussion on smog towers on Thursday to understand the implication of such decisions taken through a scientific lens and their efficacy.
The speakers at the session were Dr K V George, senior principal scientist and head, Air Pollution Control Division, NEERI; Dr Abhijit Chatterjee, associate professor, Bose Institute, department of science and technology; and Dr Harshal Salve, additional professor, AIIMS and coordinator, CAPHER (Collaborative for Air Pollution and Health effects Research, India) Dr Chatterjee said, “A smog tower is often advertised as a vaccination for ambient or outdoor air pollution. It is used widely for purifying indoor air. It can work indoors where the scope is minimal; however, installing it for the whole city is not feasible.”
