Alarming trends in Delhi’s Pollution highlighted by IIT Kanpur study

A comprehensive seven-year study conducted by IIT Kanpur has revealed disturbing trends in Delhi’s air pollution, emphasizing the urgent need for collective and sustained efforts to address the crisis.  

Rising levels of particulate matter, seasonal variations in air quality, and the impact of external and local pollution sources were among the critical issues highlighted in the study. It was found that PM2.5 concentrations in Delhi have risen by 15% over the past seven years, with the average concentration reaching 115 micrograms per cubic meter, significantly above the recommended safe limits. Seasonal spikes in pollution levels were recorded, with winter months identified as the period of the highest PM2.5 and PM10 concentrations.  

An increase of 20% in PM2.5 levels during the stubble-burning season was attributed to agricultural practices in neighboring states, adding to Delhi’s pollution burden. Vehicle emissions were reported to account for 25% of the PM2.5 pollutants, making them a significant contributor to the city’s deteriorating air quality.  

The findings were described as “alarming” by Professor S. N. Tripathi, lead researcher at IIT Kanpur. A multi-faceted approach, involving stricter regulations, improved public awareness, and inter-state collaboration, was suggested to mitigate the pollution crisis.  

The study has been acknowledged by the Delhi government, and a commitment to implement effective pollution control measures was reaffirmed. A government representative stated that collaborative efforts with experts and citizens would be undertaken to achieve measurable improvements in air quality.  

Suggestions to address the crisis include expanding eco-friendly public transport, enforcing stricter vehicle and industrial emission controls, promoting alternatives to stubble burning, and encouraging citizen participation in pollution reduction initiatives. The alarming findings have emphasized the need for immediate action. A collaborative effort involving citizens, government agencies, and other stakeholders is required to curb Delhi’s air pollution and create a healthier environment.  

By focusing on sustainable practices and effective policies, Delhi’s pollution levels can be controlled, ensuring better air quality and improved public health for future generations.
