An unprecedented attempt has been made to quantify the economic benefit due to reduction in an excess number of health risk subject to mortality/morbidity attributable to lower air pollutant (PM 2.5 , PM 10 , NO 2 , and SO 2 ) concentration in Wuhan, Paris, London, and Delhi. Ambient air quality for Delhi, London, Paris, and Wuhan cities for the lockdown month with the number of days for the years 2019 and 2020 as shown in Table 1 is considered for calculating the health damage cost due to air pollutants. ./cache/cord-306189-ugxou9z1.txt ./txt/cord-306189-ugxou9z1.txt
