Thus, the main objective of this paper is (1) to assess the impact of COVID-19 measures on air quality by evaluating the levels of air pollutants, i.e. CO, NO 2 , O 3 , SO 2 , PM 10 and PM 2.5 , between January 1 and May 31, 2020, and comparing the air quality of the lockdown interval with the same period of previous 5 years, (2) to evaluate their associations with mobility trends and (3) to empirically analyse whether or not the concentration level of air pollutants can contribute to the outbreak of COVID-19.	cache/cord-305629-utjng3dq.txt	txt/cord-305629-utjng3dq.txt
