As a result of extreme modifications in human activity during the COVID-19 pandemic, the status of air quality has recently been improved. This bibliometric study was conducted on a global scale to quantify the impact of the COVID-19 pandemic on air pollution, identify the emerging challenges, and discuss the future perspectives during the course of the ongoing COVID-19 pandemic. For this, we have estimated the scientific production trends between 2020 and 2021 and investigated the contributions of countries, institutions, authors, and most prominent journals metrics network analysis on the topic of COVID-19 combined with air pollution research spanning the period between January 01, 2020, and June 21, 2021. The search strategy retrieved a wide range of 2003 studies published in scientific journals from the Web of Sciences Core Collection (WoSCC). The findings indicated that (1) publications on COVID-19 pandemic and air pollution were 990 (research articles) in 2021 with 1870 citations; however, the year 2020 witnessed only 830 research articles with a large number 16,600 of citations. (2) China ranked first in the number of publications (n = 365; 18.22% of the global output) and was the main country in international cooperation network, followed by the USA (n = 278; 13.87% of the global output) and India (n = 216; 10.78 of the total articles). (3) By exploring the co-occurrence and links strengths of keywords "COVID-19" (1075; 1092), "air pollution" (286; 771), "SARS-COV-2" (252; 1986). (4) The lessons deduced from the COVID-19 pandemic provide defined measures to reduce air pollution globally. The outcomes of the present study also provide useful guidelines for future research programs and constitute a baseline for researchers in the domain of environmental and health sciences to estimate the potential impact of the COVID-19 pandemic on air pollution.
由于在 COVID-19 大流行期间人类活动的极端改变，空气质量状况最近得到了改善。本计量研究在全球范围内进行，旨在量化 COVID-19 大流行对空气污染的影响，确定新出现的挑战，并讨论在当前 COVID-19 大流行期间的未来展望。为此，我们估计了 2020 年至 2021 年的科学产出趋势，并调查了各国、机构、作者和最著名期刊指标网络分析对 COVID-19 与空气污染研究相结合的贡献，研究期间为 2020 年 1 月 1 日至 2021 年 6 月 21 日。搜索策略从 Web of Sciences 核心合集 (WoSCC) 检索了科学期刊中发表的 2003 项广泛研究。研究结果表明：(1)2021 年关于 COVID-19 大流行和空气污染的出版物有 990 篇(研究文章)，有 1870 条引文；然而，2020 年只有 830 篇研究文章，有大量 16600 条引文。(2)中国在出版物数量方面排名第一(n=365；占全球产出的 18.22%)，是国际合作网络中的主要国家，其次是美国(n=278；占全球产出的 13.87%)和印度(n=216；占总文章的 10.78%)。(3)通过探索关键词“COVID-19”(1075；1092)、“空气污染”(286；771)、“SARS-COV-2”(252；1986)的共现和链接强度。(4)从 COVID-19 大流行中吸取的教训为全球减少空气污染提供了明确的措施。本研究的结果还为未来的研究计划提供了有用的指导方针，并为环境和健康科学领域的研究人员提供了一个基线，以估计 COVID-19 大流行对空气污染的潜在影响。
