The epidemic of coronavirus is spreading all over the world, which is not only a health problem, but also affects the social sector, politics, the environment in various ways and the world economy. In response to the rapidly changing international epidemiological situation of COVID-19, several governments have imposed restrictions on the movement of people and vehicles and suspended industrial activities as a safety measure to reduce the spread of the virus and protect human health. This study aims to compare the state of air quality in Morocco, before the pandemic and during the lockdown situation of the Moroccan territory between March 2020 and June 2020.
