Microplastics can be present in the environment as manufactured microplastics (known as primary microplastics) or resulting from the continuous weathering of plastic litter, which yields progressively smaller plastic fragments (known as secondary microplastics). Herein, we discuss the numerous issues associated with the analysis of microplastics, and to a less extent of nanoplastics, in environmental samples (water, sediments, and biological tissues), from their sampling and sample handling to their identification and quantification. The analytical quality control and quality assurance associated with the validation of analytical methods and use of reference materials for the quantification of microplastics are also discussed, as well as the current challenges within this field of research and possible routes to overcome such limitations.

环境中的微塑料:分析化学的挑战-评论
微塑料可能以人造微塑料(称为主要微塑料)的形式存在于环境中,或者是由于塑料垃圾的持续风化而产生的,塑料垃圾的不断风化产生的塑料碎片越来越小(称为次级微塑料)。在本文中,我们讨论了与环境样品(水,沉积物和生物组织)中的微塑料以及较小程度上的纳米塑料分析相关的许多问题,从样品的采样,样品处理到鉴定和定量。还讨论了与分析方法验证以及使用参考材料进行微塑料定量相关的分析质量控制和质量保证,以及该研究领域内的当前挑战以及克服此类局限性的可能途径。
