In a recent study conducted by researchers at the Indian Institute of Technology (IIT) in Delhi, it has been found that the air quality in major cities of India has significantly improved during the nationwide lockdown imposed to curb the spread of the coronavirus. The study analyzed data from various pollution monitoring stations across the country and compared the levels of pollutants such as PM2.5, PM10, nitrogen dioxide, and ozone before and during the lockdown period. The results showed a drastic reduction in pollution levels, with some cities experiencing up to a 60% decrease in PM2.5 levels. This improvement in air quality can be attributed to the reduction in vehicular emissions, industrial activities, and construction work during the lockdown. The researchers also noted that the clear skies and improved air quality had a positive impact on public health, with fewer cases of respiratory illnesses being reported during this period. However, with restrictions being lifted and economic activities resuming, there is a concern that pollution levels may rise again. It is crucial for policymakers to take this opportunity to implement sustainable measures to maintain the improved air quality in the long term. This study highlights the importance of reducing pollution levels for a healthier environment and underscores the need for collective action to address the issue of air pollution in India.
