MUMBAI, March 6 -- The issue of rising air pollution in Mumbai was raised in the Maharashtra Assembly on Thursday, prompting speaker Rahul Narwekar to direct the state government to submit a detailed report on all construction activities underway in the city. The directive came after legislators expressed concern over worsening air quality and alleged violations of pollution control norms at construction sites. Minister of State for Urban Development Madhuri Misal told the House that action has been taken against around 1,400 construction sites for flouting environmental norms. Stop-work notices were issued and penalties imposed in several cases, she said. Narwekar directed the state government to review all construction sites across Mumbai to check compliance with pollution norms. "There should be a review of all construction sites operating in the city to examine whether pollution norms are being violated. Submit a report to me by the end of the budget session," the Speaker said....
