In response to the escalating air pollution in Mumbai, the Brihanmumbai Municipal Corporation (BMC) has taken action to dismantle four chimneys of gold and silver smelting units in the Kalbadevi and Zaveri Bazar areas of South Mumbai, officials said on Wednesday.

News agency PTI reported that the BMC's C-ward initiated these measures due to concerns that these units were contributing to the city's air pollution levels. On Wednesday, Mumbai's average air quality index (AQI) was recorded at approximately 150, placing it in the "moderate" category, according to official data.
