The preventive and cautionary measures taken by the UAE and Abu Dhabi governments to reduce the spread of the coronavirus disease (COVID-19) and promote social distancing have led to a reduction of mobility and a modification of economic and social activities. This paper provides statistical analysis of the air quality data monitored by the Environment Agency – Abu Dhabi (EAD) during the first 10 months of 2020, comparing the different stages of the preventive measures. Ground monitoring data is compared with satellite images and mobility indicators. The study shows a drastic decrease during lockdown in the concentration of the gaseous pollutants analysed (NO₂, SO₂, CO, and C₆H₆) that aligns with the results reported in other international cities and metropolitan areas. However, particulate matter (PM₁₀ and PM_2.5) averaged concentrations followed a markedly different trend from the gaseous pollutants, indicating a larger influence from natural events (sand and dust storms) and other anthropogenic sources. The ozone (O₃) levels increased during the lockdown, showing the complexity of O₃ formation. The end of lockdown led to an increase of the mobility and the air pollution; however, air pollutant concentrations remained in lower levels than during the same period of 2019. The results in this study show the large impact of human activities on the quality of air and present an opportunity for policymakers and decision-makers to design stimulus packages to overcome the economic slow-down, with strategies to accelerate the transition to resilient, low-emission economies and societies more connected to the nature that protect human health and the environment.

阿联酋和阿布扎比政府为减少冠状病毒病 (COVID-19) 的传播和促进社会疏离而采取的预防和警示措施导致流动性减少并改变了经济和社会活动。本文对阿布扎比环境署 (EAD) 在 2020 年前 10 个月监测的空气质量数据进行了统计分析，比较了预防措施的不同阶段。地面监测数据与卫星图像和移动性指标进行比较。_{研究表明，在锁定期间，分析的气态污染物（NO 2}、SO ₂、CO 和 C ₆ H ₆）的浓度急剧下降) 这与其他国际城市和大都市地区报告的结果一致。然而，颗粒物（PM ₁₀和 PM _2.5）的平均浓度与气态污染物的趋势明显不同，表明自然事件（沙尘暴）和其他人为来源的影响更大。封锁期间臭氧（O ₃）水平升高，显示出O _{3的复杂性}形成。封锁的结束导致流动性和空气污染的增加；然而，空气污染物浓度仍低于 2019 年同期水平。本研究的结果表明人类活动对空气质量的巨大影响，并为政策制定者和决策者设计刺激方案以克服经济放缓，以及加速向有弹性、低排放的经济体和社会过渡的战略，这些经济体和社会与保护人类健康和环境的自然联系更紧密。
