Assessment of microplastic content in natural waters and sediments: sampling and sample preparation
AI summary Read the abstract
Researchers reviewed and evaluated sampling and analytical methods for measuring microplastic content in natural waters and sediments, assessing sources of error and variability in current approaches. The review recommended a standardized protocol to improve cross-study comparability.
Aquatic ecosystems are the primary reservoir for microplastics entering the environment. Assessing the content of microplastics in natural waters and sediments is a critical task necessary for evaluating the pollution levels of water bodies, identifying sources of pollution, and assessing potential risks to aquatic life. To date, there is no universal analytical approach for extracting microplastics from natural waters and sediments for subsequent identification. This review summarizes information on methods of microplastic sampling from natural waters and sediments and methods of sample preparation, including techniques for separating particles by size and density, as well as methods based on the chemical decomposition of samples to remove natural organic matter. Additionally, the classification of microplastics, as well as general information about the content of microplastics in aquatic ecosystems and their potential toxicity, are described.

Methods for Studying Microplastic Pollution in Natural Waters: Current State and Recommendations
AI summary Read the abstract
This methodological review addresses the lack of standardization in how scientists sample, process, and report microplastic contamination in natural waters, which makes it nearly impossible to compare results across studies. It details quality assurance and quality control steps — especially important given how easily tiny plastic particles contaminate samples from the lab environment itself — and provides concrete recommendations for sampling protocols and data reporting. Harmonizing these methods is a critical step toward building a reliable global database of microplastic pollution.

Techniques for Collecting Micro Plastics in Freshwaters and Sediments
AI summary Read the abstract
This review examined sampling methods used across 150 studies on microplastics in freshwater bodies and sediments, finding significant variation in sampling tools, mesh sizes, and analytical approaches that make it difficult to compare results across studies. Standardizing sampling and analysis protocols is one of the most pressing needs in microplastic research. Without comparable methods, it is difficult to assess the true extent of freshwater microplastic contamination globally.
