COVID-19大流行已升级为21世纪最大的危机之一。导致COVID-19的新型冠状病毒SARS-CoV-2在全球迅速传播。鉴于病毒的迅速传播和该国的高死亡率，西班牙政府被迫宣布全国封锁。本研究调查了2020年3月15日至4月12日期间短期封锁对西班牙11个代表性城市大气CO、SO2、PM10、O-3和NO2水平的影响。还考虑了几个气象因素（温度、降水、风、日照时数、最低和最高压力）对污染物水平的可能影响。结果表明，4周的封锁对除小城市桑坦德外的所有城市的大气NO2水平以及部分城市的CO、SO2和PM10水平的降低都有显著影响，但导致O-3水平上升。(C) 2020中国科学院生态环境科学研究中心Elsevier B.V.出版
The COVID-19 pandemic has escalated into one of the largest crises of the 21st Century. The new SARS-CoV-2 coronavirus, responsible for COVID-19, has spread rapidly all around the world. The Spanish Government was forced to declare a nationwide lockdown in view of the rapidly spreading virus and high mortality rate in the nation. This study investigated the impact of short-term lockdown during the period from March 15th to April 12th 2020 on the atmospheric levels of CO, SO2, PM10, O-3, and NO2 over 11 representative Spanish cities. The possible influence of several meteorological factors (temperature, precipitation, wind, sunlight hours, minimum and maximum pressure) on the pollutants' levels were also considered. The results obtained show that the 4-week lockdown had significant impact on reducing the atmospheric levels of NO2 in all cities except for the small city of Santander as well as CO, SO2, and PM10 in some cities, but resulted in increase of O-3 level.
