Microplastics in the environment is a highly relevant research topic. However, although more and more studies on environmental concentrations of microplastics are published, a profound risk assessment could not be carried out yet. This is mainly attributable to the fact that the current sampling and analysis methods do not provide a representative picture of the environmental pollution, as the fundamental knowledge about transport processes of microplastic is not present, and the ecotoxicological studies therefore cannot consider the relevant exposures of the organisms. To provide a methodological basis for further research and risk assessments, this paper applies the Source-Pathway-Receptor model to the context of microplastics, whereby the current state of knowledge can be compiled in a structured way and important knowledge gaps can be identified.
环境中的微塑料是一个高度相关的研究课题。然而，尽管越来越多的关于环境中微塑料浓度的研究被发表，但是还不能进行深入的风险评估。这主要是因为目前的采样和分析方法不能提供环境污染的代表性图片，因为缺乏有关微塑料迁移过程的基本知识，因此生态毒理学研究不能考虑到生物体的相关暴露。为了为进一步的研究和风险评估提供方法学基础，本文将源-途径-受体模型应用于微塑料的背景下，从而可以以结构化的方式编写当前的知识状态，并确定重要的知识空白。
