From April 26 to May 5, 2020, nitrogen dioxide air pollution levels in Bogotá, Colombia have decreased by ** percent when compared to the first *** days of March, the highest reduction reported in the monitoring period. Nitrogen dioxide (NO₂) is a gaseous air pollutant and has a direct connection to fossil fuel emissions. Changes in air pollution levels are related to a reduction in industrial activity and traffic circulation in urban areas, a consequence of lockdown measures enforced in Colombia in an attempt to limit the spread of the coronavirus pandemic.
