Abstract	Chennai, a coastal city in southern India, has been grappling with rising environmental pollution in recent years. However, the COVID-19 pandemic led to a temporary reduction in pollution levels due to the nationwide lockdown. As the city slowly opens up, there are concerns that pollution levels could rise again. Chennai's air quality has been a major concern in recent years, with high levels of particulate matter and nitrogen dioxide. This is mainly due to industrial activities, vehicular emissions, and construction activities. The lockdown led to a significant reduction in vehicular traffic and industrial activities, which resulted in improved air quality. However, as the city resumes its normal activities, there is a risk of pollution levels returning to their previous high levels. The main objective of this paper is to find the possible solution for environmental pollution after COVID lockdown. Due to this heavy increase in pollution there is an increased number of diseases in chennai related to breathing and skin diseases. From the findings of this research paper it is clear that due to high usage of vehicles for transportation, industrial activities, overpopulation, etc There is high concentration of Carbon and lead emissions from both vehicular emissions and industrial activities, accumulation of heavy elements such as sulphur, cadmium, chromium, in agricultural soil due to high usage of pesticides etc… The ‘Respirable Suspended Particulate Matter’ (RSPM) that measures pollution is much beyond the permissible limit within the city. In the first week of December 2015, Chennai had the best proportion of ‘severe’ days (17.7 per cent), and a 3rd of all days were either of severe, very poor or poor air quality, averaging across Chennai’s three monitoring stations within the city. The research method followed here is a Descriptive research. A total of 204 samples have been collected out of which all samples have been collected through a convenient sampling method . The sample frame taken here is public areas in and around Chennai, Tamil Nadu like beaches, malls and parks.
Keywords	vehicles, transportation, air emissions, industrial activities, waste generation.
