二氧化氮（NO2）是自然和人为过程的结果环境痕量气体。长期暴露于NO2可能会导致广泛的严重健康问题，如高血压、糖尿病、心脏病和心血管疾病，甚至死亡。本研究的目的是研究长期暴露于NO2和冠状病毒死亡率之间的关系。Sentinel-5 P用于绘制对流层NO2分布图，NCEP/NCAR再分析用于评估大气扩散污染的能力。空间分析是在区域范围内进行的，并结合了意大利、西班牙、法国和德国66个行政区的死亡病例数。结果显示，在4443例死亡病例中，3487例（78%）发生在意大利北部和西班牙中部的五个地区。此外，同样的五个地区显示出最高的NO2浓度，加上向下的气流，这阻碍了空气污染的有效扩散。这些结果表明，长期暴露于这种污染物可能是这些地区乃至全世界COVID-19病毒造成死亡的最重要因素之一。(C)2020 Elsevier B.

Nitrogen dioxide (NO2) is an ambient trace-gas result of both natural and anthropogenic processes. Long-termexposure to NO2 may cause a wide spectrum of severe health problems such as hypertension, diabetes, heart and cardiovascular diseases and even death. The objective of this study is to examine the relationship between long-term exposure to NO2 and coronavirus fatality. The Sentinel-5P is used for mapping the tropospheric NO2 distribution and the NCEP/NCAR reanalysis for evaluating the atmospheric capability to disperse the pollution. The spatial analysis has been conducted on a regional scale and combined with the number of death cases taken from 66 administrative regions in Italy, Spain, France and Germany. Results show that out of the 4443 fatality cases, 3487 (78%) were in five regions located in north Italy and central Spain. Additionally, the same five regions show the highest NO2 concentrations combined with downwards airflow which prevent an efficient dispersion of air pollution. These results indicate that the long-term exposure to this pollutantmay be one of the most important contributors to fatality caused by the COVID-19 virus in these regions and maybe across the whole world.
