Mobility restrictions can have unexpected impacts on air quality

  • Scientists have combined air quality measurements and computer simulation data over several locations in the region.
  • Model simulations indicated that as nitrogen oxides emissions were largely reduced, chemical reactions of organic gases against atmospheric oxidants increased, slightly favoring the formation of new organic particles.
  • The conclusion is that the reduction in traffic emissions had little impact on particulate matter concentrations, possibly highlighting the importance of other emissions sources in the Po Valley area.
