ABSTRACT

Microplastics usually refer to solid plastic particles with particle size less than 5 mm. As a new type of pollutant unavoidable produced during human production and living activities, microplastics affect the ecological environment and human health safety. Since microplastics are widely distributed, small-sized microplastics and microfibers may be introduced from ambient air, sampling equipment and laboratory equipment during various monitoring process. Strict quality control measures were required to ensure the accuracy of monitoring results. In order to evaluate the compliance of quality control measures adopted in current researches, eight quality control parameters were statistically summarized by reviewing 30 published researches involving microplastic quality control methods. The results showed that those eight quality control measures could not be fully covered in most studies and uniform standardization of some key quality control measures have not been achieved. It was suggested to develop standardized operational protocols and perform cross-calibration among laboratories.

摘要

微塑料通常是指粒径小于5毫米的固体塑料颗粒。微塑料作为人类生产生活活动中不可避免产生的新型污染物，影响着生态环境和人类健康安全。由于微塑料分布广泛，在各种监测过程中，可能会从环境空气、采样设备和实验室设备中引入体积小的微塑料和微纤维。为确保监测结果的准确性，需要采取严格的质量控制措施。为了评估当前研究中采用的质量控制措施的合规性，通过回顾 30 篇已发表的涉及微塑料质量控制方法的研究，统计总结了 8 个质量控制参数。结果表明，大多数研究未能完全涵盖这八项质量控制措施，部分关键质量控制措施尚未实现统一标准化。建议制定标准化操作规程并在实验室之间进行交叉校准。
