York study: Less traffic in first UK lockdown reduced NO2 pollution but caused increase in surface ozone

Green Car Congress

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.

EPHA: Coronavirus threat greater for polluted cities; clean air returning to cities in lockdown

Green Car Congress

A 2003 study on victims of the coronavirus SARS found that patients in regions with moderate air pollution levels were 84% more likely to die than those in regions with low air pollution. Particulate matter (PM), nitrogen dioxide (NO 2 ) and ground-level ozone (O 3 ) cause the most harm and lead to about 400,000 early deaths annually.

The importance of considering non-exhaust traffic emissions; the role of EVs

Green Car Congress

Accordingly, there have been a number of recent studies working to assess the impact of non-exhaust emissions from EVs and suggesting a regulatory or policy response (e.g., A 2014 study by Weinbruch et al. Compared to earlier studies, Weinbruch et al. A new Rotterdam-specific study by a pan-European team (Tobollik et al.
