Abstract
Many governments around the world have enforced quarantine policies to control the spread of the new coronavirus (SARS-CoV-2). These policies have had positive and negative effects on the environment. For example, the concentrations of certain harmful pollutants have decreased in some countries. In contrast, the concentrations of other pollutants have increased. This research analyzes the effect of quarantine policies on air quality in Quito, Ecuador. Using a parametric approach, it was found that NO and PM2.5 concentrations have decreased significantly since the establishment of lockdown measures. However, O concentrations have increased considerably in 2020.
摘要
世界上许多政府都实施了检疫政策来控制新型冠状病毒（SARS-CoV-2）的传播。这些政策对环境产生了积极和消极的影响。例如，某些有害污染物的浓度在一些国家有所下降。相比之下，其他污染物的浓度却有所上升。本研究分析了检疫政策对厄瓜多尔基多空气质量的影响。采用参数方法发现，自实施封锁措施以来，一氧化氮（NO）和细颗粒物（PM2.5）的浓度显著下降。然而，2020年臭氧（O）的浓度大幅上升。
