Pollutants concentration change during COVID-19 in Russia 2020

Between January and May 2020, nitrogen dioxide concentration in Russia saw a decrease compared to the previous year, which could be a consequence of lockdowns during the COVID-19 pandemic. The concentration of particular matter PM10 was lower in the first four months of 2020 than in the corresponding period of 2019.

于2020年1月至5月间，相较于上一年同期，俄罗斯二氧化氮的浓度有所下降，这一变化或许可以归因于COVID-19疫情期间实施的封锁措施。2020年前四个月，细颗粒物PM10的浓度亦低于2019年同期水平。
