摘要

随着环境中微塑料的大量关注，一些研究人员开始考虑将塑料碎裂降低到较低的尺度（即亚微米级）。 术语“纳米塑料”仍然存在争议，并且不同的研究已将尺寸上限设定为1000nm或100nm。 本工作的目的是基于我们最近发表和未发表的纳米塑料研究定义，提出纳米塑料的定义。 我们将纳米塑料定义为无意产生的颗粒（即，来自塑料物体的降解和制造）并呈现出在1至1000nm的尺寸范围内的胶体行为。

With the large amount of attention being given to microplastics in the environment, several researchers have begun to consider the fragmentation of plastics down to lower scales (i.e., the sub-micrometer scale). The term "nanoplastics" is still under debate, and different studies have set the upper size limit at either 1000 nm or 100 nm. The aim of the present work is to propose a definition of nanoplastics, based on our recently published and unpublished research definition of nanoplastics. We define nanoplastics as particles unintentionally produced (i.e. from the degradation and the manufacturing of the plastic objects) and presenting a colloidal behavior, within the size range from 1 to 1000 nm.
