Impact of COVID-19 Induced Lockdown on Air Pollution and Remediation Measures

Autor: I. A. Kangiwa, M. I. Mohammed

Publikováno v: Asian Journal of Applied Chemistry Research. :43-52

Air pollution is reported to have reduced to a level that has not been recorded since the end of World War (II), and this is largely due to the global lockdown imposed to curb the spread of the novel Coronavirus disease (COVID-19) across the globe, h
