Researchers developed a living tool for the ongoing exploration of microplastic toxicity, addressing the challenge of keeping pace with the rapidly growing body of research on microplastic health effects. The study noted that despite many reports of adverse effects from microplastic exposure, the field's understanding of microplastic toxicity remains limited. The tool is designed to help scientists, regulators, and environmental managers stay current as legislative mandates require the development of health-based thresholds for microplastic pollution.

Abstract Throughout the past decade, many studies have reported adverse effects in biota following microplastic exposure. Yet, the field is still emerging as the current understanding of microplastic toxicity is limited. At the same time, recent legislative mandates have required environmental regulators to devise strategies to mitigate microplastic pollution and develop health-based thresholds for the protection of human and ecosystem health. The current publication rate also presents a unique challenge as scientists, environmental managers, and other communities may find it difficult to keep up with microplastic research as it rapidly evolves. At present, there is no tool that compiles and synthesizes the data from these studies to allow for visualization, interpretation, or analysis. Here, we present the Toxicity of Microplastics Explorer (ToMEx), an open access database and open source accompanying R Shiny web application that enables users to upload, search, visualize, and analyze microplastic toxicity data. Though ToMEx was originally created to facilitate the development of health-based thresholds to support California legislations, maintaining the database by the greater scientific community will be invaluable to furthering research and informing policies globally. The database and web applications may be accessed at https://microplastics.sccwrp.org/ . Graphical Abstract

Microplastics on the Planet: Current Knowledge and Challenges

AI summary Read the abstract

This review summarizes the current state of microplastic research worldwide, noting that while detection methods have improved, measuring nano-sized plastic particles remains a major challenge. There are still no established safety thresholds for human exposure to microplastics, and the scientific community urgently needs to develop these standards to properly assess the health risks people face.

A critical viewpoint on current issues, limitations, and future research needs on micro- and nanoplastic studies: From the detection to the toxicological assessment.

AI summary Read the abstract

This critical review examines the current methods for detecting and characterizing micro- and nanoplastics in various environmental samples, as well as reported toxic effects from in vivo and in vitro studies. The authors found that while substantial effort has been made to understand microplastic behavior, the scientific community is still far from a complete understanding of how these particles behave in biological systems. The review calls for improved standardized protocols and more studies focused on uptake kinetics, accumulation, and biodistribution.

A brief history of microplastics effect testing: Guidance and prospect

AI summary Read the abstract

This review provides a history of how scientists have tested the effects of microplastics on living organisms and finds that while study quality has improved since 2016, many methodological problems remain. Current risk assessments show that microplastic levels found in many ecosystems already exceed concentrations known to cause harmful effects in lab studies. The review offers practical guidance for researchers to design better experiments, which is essential for accurately determining the health risks of microplastic exposure.
