Description

Albertans had limited activities that could promote transmission of the COVID-19 virus during the spring 2020 public health emergency. As a result, vehicle traffic had decreased. In urban areas, emissions from vehicles contribute to nitrogen dioxide concentrations in the air. Nitrogen dioxide is an indicator of air quality that affects respiratory health and can react in the atmosphere to form secondary pollutants such as ozone and fine particulate matter. Between March 16 and April 24, 2020, following the public health emergency, concentrations of nitrogen dioxide in the air in Alberta’s largest cities, Calgary and Edmonton, were at least 14 per cent lower than in previous years.
