AQC Updates Analysis of Changes in Pollutant Concentrations Across the UK as a Result of COVID-19
Air Quality Consultants Ltd has updated its analysis of the impacts of COVID-19 social and travel restrictions on air quality. The lockdown in late March had a dramatic effect on concentrations, with NOx and NO2 concentrations reducing notably at roadside, industrial and urban sites, and roadside O3 concentrations increasing. At most sites, NOx and NO2 concentrations have remained below pre-lockdown levels since March. However, a general trend for increasing NOx and NO2 concentrations, and reducing O3 concentrations, at roadside monitors from early July has meant that, by the end of September, concentrations at some sites were close to pre-lockdown levels.
