含有石墨烯族纳米材料（GFNs）的商业产品产量的增加导致了对其释放到环境中的担忧。GFN在环境中的命运和潜在的生态毒理学效应目前尚不清楚，部分原因是GFN测量的分析方法有限。在这篇综述中，讨论了GFNs的独特性质，这些性质有助于它们的检测和量化。评估了几种技术在不同环境基质（水、土壤、沉积物和生物）、环境转化后以及从产品的聚合物基质释放后识别和/或量化GFNs的能力。本文还推荐了从环境干扰和其他碳质纳米材料中更准确地识别GFNs的提取方法和策略。总体而言，本文系统地介绍了可用于检测和量化GFN的技术的全面综述，以告知科学状况，指导研究人员为所研究的系统选择最佳技术，并使GFN计量学在环境矩阵中得到进一步发展。本文描述了两个案例研究，以提供在特定情况下选择用于GFNs检测或量化的技术的实际示例。由于现有的定量技术在一定程度上是有限的，需要更多的研究来区分GFNs与其他碳质材料，并在更环保的浓度下提高GFNs的准确性和检测限。
An increase in production of commercial products containing graphene-family nanomaterials (GFNs) has led to concern over their release into the environment. The fate and potential ecotoxicological effects of GFNs in the environment are currently unclear, partially due to the limited analytical methods for GFN measurements. In this review, the unique properties of GFNs that are useful for their detection and quantification are discussed. The capacity of several classes of techniques to identify and/or quantify GFNs in different environmental matrices (water, soil, sediment, and organisms), after environmental transformations, and after release from a polymer matrix of a product is evaluated. Extraction and strategies to combine methods for more accurate discrimination of GFNs from environmental interferences as well as from other carbonaceous nanomaterials are recommended. Overall, a comprehensive review of the techniques available to detect and quantify GFNs are systematically presented to inform the state of the science, guide researchers in their selection of the best technique for the system under investigation, and enable further development of GFN metrology in environmental matrices. Two case studies are described to provide practical examples of choosing which techniques to utilize for detection or quantification of GFNs in specific scenarios. Since the available quantitative techniques are somewhat limited, more research is required to distinguish GFNs from other carbonaceous materials and improve the accuracy and detection limits of GFNs at more environmentally relevant concentrations.
