The ubiquitous pollution of the environment with microplastics, a diverse suite of contaminants, is of growing concern for science and currently receives considerable public, political, and academic attention. The potential impact of microplastics in the environment has prompted a great deal of research in recent years. Many diverse methods have been developed to answer different questions about microplastic pollution, from sources, transport, and fate in the environment, and about effects on humans and wildlife. These methods are often insufficiently described, making studies neither comparable nor reproducible. The proliferation of new microplastic investigations and cross-study syntheses to answer larger scale questions are hampered. This diverse group of 23 researchers think these issues can begin to be overcome through the adoption of a set of reporting guidelines. This collaboration was created using an open science framework that we detail for future use. Here, we suggest harmonized reporting guidelines for microplastic studies in environmental and laboratory settings through all steps of a typical study, including best practices for reporting materials, quality assurance/quality control, data, field sampling, sample preparation, microplastic identification, microplastic categorization, microplastic quantification, and considerations for toxicology studies. We developed three easy to use documents, a detailed document, a checklist, and a mind map, that can be used to reference the reporting guidelines quickly. We intend that these reporting guidelines support the annotation, dissemination, interpretation, reviewing, and synthesis of microplastic research. Through open access licensing (CC BY 4.0), these documents aim to increase the validity, reproducibility, and comparability of studies in this field for the benefit of the global community.

EXPRESS：提高微塑料研究的可重复性和可比性的报告指南

微塑料（多种污染物）对环境的普遍污染越来越受到科学界的关注，目前受到了公众、政治和学术界的广泛关注。近年来，微塑料对环境的潜在影响引发了大量研究。人们已经开发出许多不同的方法来回答有关微塑料污染的不同问题，包括来源、运输和环境中的归宿，以及对人类和野生动物的影响。这些方法往往描述不充分，使得研究既不可比较也不可重复。用于回答更大规模问题的新微塑料研究和交叉研究合成的扩散受到阻碍。这个由 23 名研究人员组成的多元化小组认为，通过采用一套报告指南可以开始克服这些问题。此次合作是使用开放科学框架创建的，我们详细介绍了该框架以供将来使用。在这里，我们建议在典型研究的所有步骤中为环境和实验室环境中的微塑料研究制定统一的报告指南，包括报告材料、质量保证/质量控制、数据、现场采样、样品制备、微塑料识别、微塑料分类的最佳实践，微塑料定量以及毒理学研究的注意事项。我们开发了三个易于使用的文档：详细文档、清单和思维导图，可用于快速参考报告指南。我们希望这些报告指南支持微塑料研究的注释、传播、解释、审查和综合。通过开放获取许可（CC BY 4.0），这些文件旨在提高该领域研究的有效性、可重复性和可比性，以造福全球社会。
