The present study aims to provide evidence on the effects of pandemic curtailment measures on public health, targeting the changes in breathable air quality, within urban areas. The analyzed period covers the full impact of lockdowns in Europe in 2020. We used everyday data for each analyzed pollutant, NO, SO CO, PM and PM, from urban monitoring stations that provided real-time concentrations (provided by Copernicus Atmosphere Monitoring Service, Environmental Protection Agency repository and European Environment Agency map services) and satellite data (provided by NASA Orbiting Carbon Observatory 2). In the present study, the urban air quality was computed using a composite index that was further analyzed in comparison with pandemic restrictions. Descriptive statistics, charts and maps were used to visualize the data that covered the analyzed countries. Our results show that air pollution was reduced by 12% after lockdowns in European urban areas, with a 0.76 correlation between air pollution and pandemic restrictions. All air pollutants registered significant drops.
本研究旨在提供有关大流行限制措施对城市地区空气质量影响的证据，重点研究可呼吸空气质量的变化。分析期间涵盖了 2020 年欧洲全面封锁的影响。我们使用了来自城市监测站的每种分析污染物（NO、SO、CO、PM 和 PM）的日常数据，这些监测站提供实时浓度（由哥白尼大气监测服务、环境保护署存储库和欧洲环境署地图服务提供）和卫星数据（由美国宇航局轨道碳观测站 2 号提供）。在本研究中，使用综合指数来计算城市空气质量，并用该指数进一步与大流行限制进行比较分析。描述性统计数据、图表和地图用于可视化涵盖分析国家的数据。我们的研究结果表明，欧洲城市地区实施封锁后，空气污染减少了 12%，空气污染与大流行限制之间存在 0.76 的相关性。所有空气污染物的浓度均显著下降。
