Flanked by the Deonar dumping ground on one side and refineries and chemical factories on the other, M-West is one of the most polluted wards in the city. Residents of Chembur and Mahul complain that the dense pollution in their areas has made life a constant ordeal. Locals blame the respiratory ailments that are rampant in MWest on the proximity to the dumping ground, a recently setup bio-medical waste incinerator and industrial units.
