Plastics in Freshwater Bodies
AI summary Read the abstract
This review provides a comprehensive assessment of methods for monitoring and modeling plastics -- from macroplastics to nanoplastics -- in freshwater bodies including rivers and lakes, mapping global study distributions. It identifies four key knowledge gaps warranting greater attention: temporal variation, cross-compartment transfer, harmonization of size ranges across monitoring and modeling studies, and data quality control.
Considering everything between macroplastics and nanoplastics, this chapter aims to provide a comprehensive and detailed assessment of the available methods to monitor and model plastics in freshwater bodies and to visualize the geographical distribution of studies reporting plastics in rivers and lakes. Both in marine or freshwater ecosystems, five steps can be distinguished for monitoring, namely, sampling, extraction, analysis, identification, and extrapolation. Despite the rapidly increasing number of publications on plastic occurrences in freshwater bodies, several aspects still carry high levels of uncertainty. The chapter highlights four key aspects that deserve more attention when designing and performing monitoring campaigns and when developing and interpreting numerical models. These four aspects are: temporal variation, transfer between environmental compartments, harmonization of monitoring and modeling investigations regarding plastic size ranges, and, finally, data quality control and validation of results.

Hydro-geomorphic perspectives on microplastic distribution in freshwater river systems: A critical review
AI summary Read the abstract
This critical review examined 92 case studies on microplastic distribution in freshwater river systems and highlighted major gaps in how researchers quantify and compare pollution levels. The study found that spatiotemporal aspects and transport mechanisms linking microplastic sources and sinks are insufficiently understood. Researchers developed a new procedure for comparing microplastic measurements across water and sediment samples, offering a path toward more standardized pollution assessment.

This review provides a comprehensive overview of microplastic pollution in freshwater environments, covering sources, distribution, and ecological impacts in rivers, lakes, and reservoirs. Researchers found that freshwater microplastic contamination is widespread globally but that standardized sampling and analysis methods are still lacking. The study calls for more consistent research approaches so that contamination levels across different water bodies can be meaningfully compared.

Beyond the ocean: contamination of freshwater ecosystems with (micro-)plastic particles
AI summary Read the abstract
This review examined the available data on microplastic contamination in freshwater ecosystems — rivers, lakes, and urban water systems — and found it to be widespread globally, though often underreported compared to marine environments. The authors highlight the need for reliable concentration data and chemical characterization of freshwater plastics to properly assess ecological risk.
