In December 2019 the deadly pandemic COVID-19 traumatized mankind through its lethal impact. To seize the outbreak, nationwide/region-based lockdown strategies were adopted by most of the COVID-19 affected countries. This in turn resulted in restricted transportation via surface, water, and air, as well as significantly reduced working hours of the industry sectors, so on and so forth. The obvious outcome was a sudden discernible decline in atmospheric adulteration. Accordingly, the anthropogenic emissions at the global and regional/local scales were examined during the lockdown period by several researchers using both or either satellite-based and ground-based monitoring. Among several other air-contaminants, carbon has a dominant toxicological profile causing adverse health effects and thereby attracting researches interest in carbon-release probing during the systematic confinement period imposed by the ruling authorities across the globe. The results of those studies indicated a confirmed decline in carbon emission/concentration making the air more breathable for the period. In this review, the studies related to anthropogenic emissions of carbon during the lockdown period are accounted for by compiling the recently reported data from published articles.
2019年12月，致命的新冠疫情以其致命影响给人类带来创伤。为控制疫情爆发，大多数受新冠疫情影响的国家都采取了基于全国/地区的封锁策略。这反过来导致地面、水路和航空运输受限，以及各行业工作时间大幅减少，等等。明显的结果是大气污染突然明显下降。因此，在封锁期间，一些研究人员使用基于卫星和地面的监测手段，对全球和区域/地方尺度的人为排放进行了研究。在其他几种空气污染物中，碳具有主要的毒理学特征，会对健康产生不利影响，因此在全球各国政府实施的系统性封锁期间，引发了研究人员对碳释放探测的兴趣。这些研究结果表明，碳排放/浓度确实下降，使这段时间的空气更易于呼吸。在这篇综述中，通过汇编近期发表文章中报告的数据，阐述了与封锁期间碳的人为排放相关的研究。
