Air Quality Tracker: Delhi National Capital Region

August 06, 2024

Centre for Science and Environment (CSE) has alerted from time to time about the growing problem of ground-level ozone in Indian cities. While policy and public attention is nearly fully drawn towards very high level of particulate pollution, the challenge of this highly toxic gas has not attracted adequate policy attention for mitigation and prevention. Inadequate monitoring, limited data and inappropriate methods of trend analysis have weakened the understanding of this growing public health hazard. This requires early action.

The summer of 2024 has witnessed widespread ground-level ozone exceedance making the air of Delhi-NCR even more toxic. This summer the geographical spread of the problem is even more wide spread than observed during lockdown summer of 2020. The toxic built up is lasting much longer this summer at locations where it is happening.
