Changes in outdoor air pollution due to COVID-19 lockdowns

2020/11/01· Mean outdoor PM 2.5 concentrations in 2020 were much lower than during the same period in 2019 (p<0.001). However, despite UK motor vehicle journeys reducing by 65%, concentrations in 2020 were within 1 µg/m 3 of those measured in 2017 (p=0.66) and 2018 (p<0.001), suggesting that traffic-related emissions may not explain variability of PM 2.5 in outdoor air in Scotland.
