In December 2019, an outbreak of the COVID-19took place in Wuhan, China which spread to almost all the parts of world. It was declared a global pandemic in March 2020 by the World Health Organization (WHO). The outbreak of the corona virus has emerged as one of the deadliest pandemics in human history. The ongoing COVID-19 pandemic has forced many countries around the world to look for a complete lockdown that forced people to stay in their homes. India also faced a total closure phase for 21 days (first phase) to prevent the spread of coronavirus at a very high rate. The closure contributed to decline in the pollution levels and improved air and water quality in the short term due to very limited human activities. In this project work available data on the state of air pollution before and after lockdown had been analyzed to develop a strategy for dealing with the increased pollution level in Jharkhand, India. The analysis was based on pre-lock and post-lock air quality data (first 21-day period) for 21 days each. The results showed a significant decrease in the considered air pollution indicators and showed an improvement in air quality in Jharkhand. Significant impact was observed at PM2.5, NO2 and CO levels. SO2 levels showed a slight decrease during closure. The results are presented with future ideas for reducing air pollution soon by adopting short and periodic closures as a tool. Based on the information provided by the JSPCB changes in Jharkhand air quality was analyzed before and after Lockdown.
