摘要

微塑料污染的研究涉及对大量微塑料的多学科分析。因此，提供塑料污染的概览是费时的，尽管进行了大量的分析，但仍然是一项重大挑战。本研究的目的是提出一种方案，确定必须分析多少微塑料，以提供一个具有代表性的观点的粒度分布和化学性质，并计算相关的边际误差。基于塔拉地中海战役的微塑性数据，通过不同的实例对该方法进行了解释。在这个特殊的例子中，结果显示，仅需要对收集到的3%的微塑料进行分析，就可以准确地看到西北地中海盆地的规模(误差<5%)，而对每只螳螂进行概览(误差<10%)则需要对17.7%的微塑料进行分析。该方法对微塑性研究具有重要的实用价值。

Abstract

The study of microplastic pollution involves multidisciplinary analyses on a large number of microplastics. Therefore, providing an overview of plastic pollution is time consuming and, despite high throughput analyses, remains a major challenge. The objective of this study is to propose a protocol to determine how many microplastics must be analyzed to give a representative view of the particle size distribution and chemical nature, and calculate the associated margin error. Based on microplastic data from Tara Mediterranean campaign, this approach is explained through different examples. In this particular case, the results show that only 3% of the collected microplastics need to be analyzed to give a precise view on the scale of the North West Mediterranean Basin (error <5%), and 17.7% to give an overview manta per manta (error <10%). This approach could be an important practical contribution to microplastic studies.
