Abstract
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.
Highlights
The Covid-19 is an emerging pandemic of an infectious new disease, caused by the coronavirus SARS-CoV-2, which appeared in Wuhan on November 17, 2019[1], before spreading around the world
The Covid-19 epidemic was declared a pandemic by the World Health Organization (WHO) on March 11, 2020, which calls for essential protective actions to prevent overcrowding in intensive care units and to strengthen preventive hygiene [3]
Nitrogen Dioxide (NO2) is one of a group of gases nitrogen oxides (NOx). It is a dangerous pollutant in and of itself. While all of these gases are harmful to human health and the environment, NO2 is of greater concern
Summary
The Covid-19 is an emerging pandemic of an infectious new disease, caused by the coronavirus SARS-CoV-2, which appeared in Wuhan on November 17, 2019[1], before spreading around the world. The Covid-19 epidemic was declared a pandemic by the WHO on March 11, 2020, which calls for essential protective actions to prevent overcrowding in intensive care units and to strengthen preventive hygiene [3] This global pandemic is causing a series of cancellations of sporting and cultural events around the world, the implementation by many countries of containment measures to curb the formation of new outbreaks of contagion and the closure of borders in many countries [4]. The lockdown due to the health situation in the world and in Morocco linked to COVID-19 has reduced air and road traffic, resulting in lower energy consumption and lower demand for oil This has been observed since the start of the lockdown, in particular through the analysis of the measurements resulting from the monitoring of air quality [9]
