The COVID-19 epidemic seriously threats the human society and provokes the panic of the public. Personal Protective Equipment (PPE) are widely utilized for frontline health workers to face the ongoing epidemic, especially disposable face masks (DFMs) to prevent airborne transmission of coronavirus. The overproduction and massive utilization of DFMs seriously challenge the management of plastic wastes. A huge amount of DFMs are discharged into environment, potentially induced the generation of microplastics (MPs) owing to physicochemical destruction. The MPs release will pose severe contamination burden on environment and human. In this review, environmental threats of DFMs regarding to DFMs fate in environment and DFMs threats to aquatic and terrestrial species were surveyed. A full summary of recent studies on MPs release from DFMs was provided. The knowledge of extraction and characterizations of MPs, the release behavior, and potential threats of MPs derived from DFMs was discussed. To confront the problem, feasible strategies for control DFMs pollution were analyzed from the perspective of source control and waste management. This review provides a better understanding the threats, fate, and management of DFMs linked to COVID-19 pandemic.
新型冠状病毒肺炎疫情严重威胁人类社会，引发公众恐慌。个人防护装备（PPE）被广泛应用于一线医护人员，以应对当前疫情，特别是一次性医用口罩（DFM）可防止冠状病毒的空气传播。DFM 的过度生产和大量使用对塑料废物管理提出了严峻挑战。大量的 DFM 被排放到环境中，由于物理化学破坏，可能会产生微塑料（MPs）。MPs 的释放将对环境和人类造成严重的污染负担。在本综述中，调查了 DFM 对环境的环境威胁，包括 DFM 在环境中的命运以及 DFM 对水生和陆生物种的威胁。提供了关于 DFM 中 MPs 释放的最新研究的全面总结。讨论了从 DFM 中提取和表征 MPs、释放行为以及 MPs 的潜在威胁。为了解决这一问题，从源头控制和废物管理的角度分析了控制 DFM 污染的可行策略。本综述有助于更好地了解与 COVID-19 大流行相关的 DFM 的威胁、命运和管理。
