在废物管理过程中，与嵌入产品的工程纳米材料（ENM）的命运相关的重大知识和数据差距限制了我们目前制定适当的报废管理战略的能力。本审查文件是作为IWWG废物环境监测工作组活动的一部分编写的。本审查文件的具体目标是评估目前与常用废物管理流程中的无害环境物质归宿有关的知识，包括与每个废物管理流程中的无害环境物质归宿和迁移有关的关键流程和机制，并利用这些信息确定这一领域的数据差距和研究需求。回顾和总结了与废物中ENM归宿相关的文献。总的来说，从这个文献综述的结果表明，需要在这一领域继续研究。尚未开展量化废弃材料中存在的ENM的工作，需要了解在相关废物管理过程中发现的代表性条件下消费品中的ENM释放。研究结果还表明，存在重大的知识差距与ENM行为的每个废物管理过程中调查。有必要进行更多的研究，调查不同类型的ENM在更大的浓度范围内与不同的表面化学的命运。还需要了解治疗过程操作的变化如何影响ENM的命运。一系列具体的研究问题与含ENM废物的管理过程中的ENM的命运已经确定，并用于指导未来的研究在这一领域。
Significant knowledge and data gaps associated with the fate of product-embedded engineered nanomaterials (ENMs) in waste management processes exist that limit our current ability to develop appropriate end-of-life management strategies. This review paper was developed as part of the activities of the IWWG ENMs in Waste Task Group. The specific objectives of this review paper are to assess the current knowledge associated with the fate of ENMs in commonly used waste management processes, including key processes and mechanisms associated with ENM fate and transport in each waste management process, and to use that information to identify the data gaps and research needs in this area. Literature associated with the fate of ENMs in wastes was reviewed and summarized. Overall, results from this literature review indicate a need for continued research in this area. No work has been conducted to quantify ENMs present in discarded materials and an understanding of ENM release from consumer products under conditions representative of those found in relevant waste management process is needed. Results also indicate that significant knowledge gaps associated with ENM behaviour exist for each waste management process investigated. There is a need for additional research investigating the fate of different types of ENMs at larger concentration ranges with different surface chemistries. Understanding how changes in treatment process operation may influence ENM fate is also needed. A series of specific research questions associated with the fate of ENMs during the management of ENM-containing wastes have been identified and used to direct future research in this area.
