Delhi’s Ozone Levels Spike Sharply In Many Areas, Raising Alarms Over Public Health
Ozone pollution has surged to alarming levels in several parts of the capital, reaching nearly twice the permissible limit. According to SAFAR, a monitoring agency under the Ministry of Earth Sciences, ozone concentration near the Major Dhyan Chand National Stadium hit 239 micrograms per cubic meter on Tuesday. As per national air quality standards, this level should not exceed 100 micrograms per cubic meter. Scientists note that while ozone spikes were previously confined to the summer months, the trend has now become a year-round concern in many parts of the country. Elevated ozone levels can damage the lungs and significantly increase the risk of heart disease, making it a growing public health threat. Unlike other pollutants, ozone doesn’t have a single direct source. Instead, during extreme heat, emissions from vehicles and power plants react in the atmosphere to form ozone, leading to a rise in its levels. According to a report by the Centre for Science and Environment (CSE), many Indian cities have witnessed a worrying increase in ozone pollution. This summer, ten major cities recorded dangerously high ozone levels, with Delhi being the most affected. The report, titled “An Invisible Threat: Air Quality Tracker”, analyzed ozone trends in Delhi-NCR, Bengaluru, Mumbai, Chennai, Kolkata, Pune, Greater Ahmedabad, Greater Hyderabad, Greater Jaipur, and Greater Lucknow. The findings revealed that ozone levels rose more sharply between January and March compared to the summer months of April to July. Ahmedabad reported an astonishing 4000-fold increase in ozone levels compared to last year, while Pune saw a 500 per cent rise and Jaipur recorded a 152 per cent jump.
