DECEMBER 27, 2020

Less traffic on the roads during the first COVID-19 lockdown in the UK led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise, according to a new study led by researchers at the University of York. The problem is being created by the change in chemistry between NO x and O 3.
