Two studies led by María Morales Suárez Varela, group leader of the CIBERESP at the University of Valencia and professor of the Department of Preventive Medicine and Public Health at the academic institution, have evaluated the impact of mobility restrictions on air quality and polluting emissions, in Valencia and in three Italian cities. “The lockdown measures improved air quality in urban areas, but not as much as expected given the alleged contribution of traffic to ambient air pollution,” explains Morales. “The restrictive mobility measures to limit the spread of COVID-19 provided a unique opportunity to improve our understanding of the impact of mobility on air pollution in urban areas.”
