Abstract

The outbreak of coronavirus ailments (COVID-19) in 2019 resulted in public health crisis leading to global pandemonium. In response to the high prevalence of disease transmission, governments all around the globe implemented emergency measures in various routes (e.g., social distancing, personal hygiene, and disinfection of public/private places) to curb/contain COVID-19 infections. The social media infodemic, released as uncensored publishing and/or views/recommendations, also triggered large-scale behavior changes such as the overuse of advanced sanitation products (ASPs) containing nanomaterials. The majority of these ASPs contain silver nanoparticles (AgNPs) as an active ingredient to enhance their antimicrobial potential. Ecotoxicological concerns such as the transformation and degradation of these AgNP-infused products in terrestrial or aquatic environments are under the jurisdiction of the EPA. However, they are not considered in the FDA approval process. In light of excessive consumption of ASPs, it is time to consider their ecotoxicological screening prior to market approval jointly by the FDA and EPA, along with the implementation of post-market surveillance strategies. At the same time, efforts should be put into running awareness programs to prevent the overuse of ASPs.

摘要

2019年冠状病毒病(COVID-19)的爆发引发了公共卫生危机,导致全球一片混乱。为应对疾病传播的高发生率,全球各国政府通过各种途径实施了紧急措施(如保持社交距离、个人卫生以及对公共场所/私人场所进行消毒),以遏制/控制COVID-19感染。作为未经审查的发布内容和/或观点/建议而出现的社交媒体信息疫情,也引发了大规模行为变化,比如过度使用含有纳米材料的高级卫生用品(ASP)。这些ASP大多含有银纳米颗粒(AgNP)作为活性成分,以增强其抗菌潜力。诸如这些注入AgNP的产品在陆地或水生环境中的转化和降解等生态毒理学问题,属于美国环境保护局(EPA)的管辖范围。然而,美国食品药品监督管理局(FDA)的审批过程中并未考虑这些问题。鉴于ASP的过度消费,现在是时候考虑在FDA和EPA联合进行市场批准之前对其进行生态毒理学筛查,并实施上市后监测策略了。与此同时,应努力开展宣传活动,防止过度使用ASP。
