Experts say that heavy traffic, refineries in Chembur-Trombay, and coastal humidity increase ozone levels in winter. The CPCB and MPCB have repeatedly recorded ozone levels above the WHO safe limits.
Doctors warn that this can cause sore throat, cough, and shortness of breath. Prolonged exposure affects the lungs, and children, the elderly, and those who work outdoors are most at risk.
Dr. Sanket Jain states that 2.1 million people die every year in India due to air pollution. In Mumbai, mortality rates are rising rapidly due to exposure to O₃, NO₂, and PM2.5, compounded by high pollution, lack of healthcare, and dense population.
He explains that polluted air increases the risk of asthma, COPD, bronchitis, heart disease, stroke, and high blood pressure, and is also linked to brain damage, pregnancy complications, and premature birth.
According to the environment department, intense sunlight, humidity, and low wind speed increase ozone levels, with spikes most visible in Andheri, Bandra, and Chembur.
Officials say that reducing pollution requires cutting vehicle and industrial emissions, controlling VOCs, increasing public transport, promoting e-vehicles, and planting more trees in the city.
