In a recent study conducted by the Indian Institute of Technology (IIT), it was revealed that the air quality in major cities across India has significantly improved during the lockdown period. The study analyzed data from various pollution monitoring stations and found that the levels of harmful pollutants such as PM2.5 and PM10 have decreased by up to 50% in some cities. This improvement in air quality can be attributed to the reduction in vehicular traffic and industrial activities due to the nationwide lockdown imposed to curb the spread of COVID-19. The findings of the study highlight the impact of human activities on the environment and underscore the importance of sustainable practices to maintain a clean and healthy atmosphere. The researchers also noted that the improvement in air quality could have positive effects on public health, as exposure to high levels of air pollution has been linked to respiratory diseases and other health issues. However, the study also cautions that the gains in air quality may be temporary, and measures need to be taken to ensure that pollution levels remain low even after the lockdown is lifted. The results of the study have raised awareness about the need for long-term solutions to address air pollution in India, such as promoting renewable energy sources, implementing stricter emission norms, and encouraging public transportation. With the data showing a significant improvement in air quality during the lockdown, there is hope that India can work towards a cleaner and greener future for its citizens.
