Ozone pollution spreading across Indian cities, Delhi-NCR worst hit
Ground-level ozone, an invisible but highly harmful air pollutant, is rapidly emerging as a year-round public health and climate challenge across India's cities, according to a new analysis by the Centre for Science and Environment (CSE). Based on six years of data from 25 cities, the study shows that ozone pollution is no longer confined to isolated summer spikes or a handful of northern urban centres. Instead, it has spread across regions, with prolonged exposure becoming increasingly common in both inland and coastal cities.
