环境中存在的微塑料分析原理

[中文适用范围]： 本文件描述了分析各种环境基质中的微塑料时应遵循的原则。这包括塑料的独特粒度分类、采样、样品制备和代表性样品量的确定方面的某些设备的使用。本文件的目的是指定最低要求，直到针对不同情况的具体标准可用。这对于确保以一致的方式制定具体标准以确保可以比较或关联结果非常重要。本文件不包括监测行动的要求。 [外文原描述]： This document describes the principles to be followed in the analysis of microplastics in various environmental matrices. This includes the unique particle size classification of plastics, the use of certain apparatus with regard to sampling, sample preparation, and the determination of representative sample quantities. The purpose of this document is to specify minimum requirements until specific standards for the different case situations are available. This is important to ensure that the development of the specific standards is done on a consistent basis to ensure that comparison or correlation of results is possible. This document does not include requirements for monitoring actions.
