Same but different: A framework to design and compare riverbank plastic monitoring strategies
AI summary Read the abstract
Researchers proposed a standardized framework for designing and comparing riverbank plastic monitoring strategies, identifying four common elements shared across existing methods to facilitate harmonization of data collection. The framework aims to help scientists and practitioners balance research objectives against available resources, improving cross-study comparability of macroplastic litter data.
Plastic pollution in rivers negatively impacts human livelihood and aquatic ecosystems. Monitoring data are crucial for a better understanding of sources, sinks and transport mechanisms of riverine macroplastics. In turn, such understanding is key to develop effective plastic pollution prevention, mitigation and removal strategies. Riverine plastic has been observed in all compartments, of which floating macroplastic and riverbank plastic are most frequently studied. Existing riverbank plastic measurement methods vary greatly, which complicates direct comparison of data collected with different methods. We present a framework to better compare and to aid the design of riverbank plastic monitoring methods, which is based on four common elements distilled from riverbank (plastic) litter monitoring methods currently in use. This framework can be used by scientists and practitioners to find the right trade-offs between the data required to answer specific research questions, and the available resources. With this paper, we aim to provide a first step towards harmonization of riverbank (plastic) litter monitoring efforts.

This review examines two decades of microplastic monitoring in aquatic systems, identifying persistent challenges in harmonizing methodologies for sampling, analysis, and reporting that hinder data comparison, and proposing improvements to create comparable datasets for assessing plastic pollution from river basins to the ocean.
Measuring riverine macroplastic: Methods, harmonisation, and quality control
AI summary Read the abstract
This critical review examined methods for measuring macroplastic flows in rivers, finding substantial variability in approaches and reporting that limits comparability across studies. The authors call for methods testing, harmonized quality assurance procedures, and standardized data reporting to support a rigorous evidence base for global plastic pollution reduction efforts including the forthcoming treaty.
Estimating plastic pollution in rivers through harmonized monitoring strategies
AI summary Read the abstract
This study characterized microplastic contamination in surface water and fish from rivers flowing through areas with varying land use, finding that agricultural and urban catchments consistently had higher microplastic concentrations than forested reference catchments. The results provide evidence that land use is a primary predictor of riverine microplastic contamination.
