The outbreak of novel coronavirus pandemic has caused problems all over the world. Many people all over the world have lost their lives due to the severeness of the disease. The origin of the infection was the exposure of people to Huanan seafood market in Wuhan city of China. The malady has caused huge economic losses across the globe. Since it is a respiratory disease, the air quality in the region also plays a major role in determining the degree of the severeness of disease. Many places all over the world due to high levels of pollution have reported a large number of deaths. The regions with cold climatic conditions and have reported a higher number of cases in comparison to the countries with warm climatic conditions. The climatic conditions also affect the immunity power of people living in the area. As a result of this, the people of warmer conditions have stronger immunity and thus do not suffer to a large extent from the disease. Italy has reported a large number of infected cases of SARS-CoV-2 and also uncontrolled increase in the death toll in the initial stage. This study focuses on the comparison of levels of NO 2 , AOD and O 3 in Italy during the COVID-19 malady and in the previous year to determine the reduction in levels of these as a result of lockdown. The concentration of these pollutants had a drastic impact on the severity of the disease in the country. The announcement of lockdown in the country helped in the reduction of these pollutants thereby improving the air quality. This also helped in controlling the number of infected cases and also reduces the number of deaths due to infection.
