India's nationwide shutdown began on March 25, 2020. More lockdown phases were added throughout time, and strict restrictions were gradually relaxed as part of the unlocking process, which got underway on June 1st, 2020. Despite being challenging and laborious, the lockout and stage wise unlock periods gave us the ability to gradually assess the air load of automotive pollution. Although doing so would aid policymakers in setting vehicle regulations for a long-term solution to automotive pollution, the bulk of research carried out so far do not contrast pre- and post-lockdown times. The fluctuation of mutually supportive trace chemicals in the atmosphere in accordance to the boldness of their anthropogenic sources would be really fascinating to study. The pandemic-induced lockdown proved to be a blessing in disguise for studying the natural purifying procedures of the environment because there aren't many such studies on India. The alleged enhancements in air quality during the lockdown may serve to relieve severe the COVID-19 distress issue. A consensus on reasonable restrictions for the industrial and transportation industries to minimize trace gas emissions from various anthropogenic sources across the country is created via scientific literature on air quality. In this review, an effort has been directed to elucidate the pattern of air pollution fluctuations that were observed during, before, and after the lockdown, in India, with specific emphasis on the city of Hyderabad.
