Why should we matter about fluvial ecosystems with biofilm-embedded microplastics?
AI summary Read the abstract
This paper asks why fluvial (river) ecosystems with biofilm-embedded microplastics should be a research priority. It is listed as an international audience paper but the abstract contains only that phrase, offering no detail on findings.

The role of biofilm and hydrodynamics on the fate of microplastic particles in rivers: an experimental study
AI summary Read the abstract
Researchers conducted experimental flume studies to investigate how biofilm formation and hydrodynamic conditions jointly govern microplastic particle fate in rivers, examining why some urbanized and industrialized river reaches show no significant upstream-to-downstream increase in microplastic concentration despite theoretical inputs.
Interactions between microplastics and benthic biofilms in fluvial ecosystems: Knowledge gaps and future trends
AI summary Read the abstract
This review examines the interactions between microplastics and benthic biofilms in freshwater ecosystems, identifying key knowledge gaps around how biofilms influence microplastic fate and transport, and calling for more field-based research to understand these complex ecological relationships.
Investigation of microplastic biofilm communities originated from freshwater
AI summary Read the abstract
Microplastic surfaces in freshwater develop biofilm communities structurally distinct from surrounding water, with specific bacterial taxa dominating depending on whether conditions are nutrient-rich or ambient, regardless of plastic polymer type. These unique MP-associated microbial communities matter because they can alter nutrient cycling, harbor potential pathogens, and serve as vehicles for spreading antimicrobial resistance through aquatic ecosystems.
The role of biostabilisation in controlling microplastic flux in rivers
AI summary Read the abstract
This conference abstract explores how biofilm formation on river sediments controls whether microplastics are retained within riverbeds or transported downstream to the ocean. Biological stabilization of sediments by microbes reduces the flux of microplastics through river systems, a factor not yet incorporated into most transport models.
Microplastic Contamination in Water Bodies: Sources, Fate, and Ecological Impacts in Native Rivers
AI summary Read the abstract
Tiny plastic bits are ending up in rivers, even remote ones far from cities, coming from trash breakdown, wastewater, and even air. This review of existing research shows these particles can harm river life by physically injuring them and releasing or carrying harmful chemicals, which matters because these same waterways often feed into our drinking water and food supply. Scientists still need better tools to measure the problem and stronger policies to stop plastic pollution at its source.
