How the epidemic affects smog?
The COVID-19 pandemic has reduced smog and improved air quality. Because of
precautions, people drive cars less. Also air transport has been limited. This
helped to reduce the amount of exhaust gas in the air. In addition, many factories
were closed for some time, so that pollution and toxic gases did not get into the
air. Many offices and buildings were also closed, so they did not have to be
heated. And as you know, heating installations are the biggest problem in the fight
against smog.
