Covid 19 air pollution

 Air pollution dropped significantly during the pandemic 

During the pandemic period, air pollution levels experienced fluctuations due to changes in human activity. Initially, lockdowns and restrictions led to a decrease in pollution levels in some areas as transportation and industrial activities slowed down. However, as restrictions eased, pollution levels began to rise again. The overall impact varied depending on location and specific policies implemented to address pollution during the pandemic.

Furthermore, the reduction in vehicular traffic and industrial output during the initial phases of the pandemic also led to noticeable improvements in air quality in many urban areas. Cities that were previously plagued by high levels of particulate matter and nitrogen dioxide saw significant declines in these pollutants. This temporary respite from pollution had some positive effects on public health, with reports of decreased respiratory issues and clearer skies being observed in various regions. However, as lockdown measures were relaxed and economic activities resumed, pollution levels gradually returned to pre-pandemic levels or even exceeded them in some cases. This rebound effect underscored the complex interplay between human activity and environmental health, highlighting the need for sustainable practices and policies to mitigate air pollution in the long term. Ultimately, the pandemic served as a stark reminder of the interconnectedness between human actions and environmental consequences, prompting renewed efforts to address air quality issues globally.
