Low microplastic loads in riverine European eel (Anguilla anguilla) from southwest England during their marine–freshwater transition
Summary
This study found very low levels of microplastic contamination in juvenile European eels (elvers) from three rivers in southwest England, with only 3.3% of individuals carrying particles. While contamination levels were low, the results establish a baseline for monitoring trends in this critically endangered migratory fish species.
The microplastic loads in elvers of the critically endangered European eel Anguilla anguilla, sampled in the lower reaches of three English rivers, were very low (incidence: 3.3%, mean ± s.d.: 0.03 ± 0.18 particles) and did not vary with body length or between rivers. Particles were mostly black, polyolefins, fibres and fragments of size 101-200 μm. Current levels indicate a low contamination pressure locally and, consequently, management efforts might prioritise mitigating the effects of other stressors affecting the species.

Microplastics across biomes in diadromous species. Insights from the critically endangered Anguilla anguilla
Researchers examined microplastic ingestion in young European eels across freshwater and marine environments, finding these critically endangered diadromous fish are exposed to microplastic contamination in both habitats throughout their life cycle.
Endangered, exploited glass eels (Anguilla anguilla) with critical levels of heavy metals and microplastics reveal both shipping and plastic spill threats
Researchers measured heavy metals and microplastics in endangered European glass eels and the estuarine waters they pass through in the Bay of Biscay region. They found that cadmium levels in eels from all estuaries exceeded legal European limits, and some waterways showed microplastic concentrations above ecotoxicological thresholds. The findings highlight the compounding threats that chemical and microplastic pollution pose to this already critically endangered species.
Presence of microplastic in the digestive tracts of European flounder, Platichthys flesus, and European smelt, Osmerus eperlanus, from the River Thames
Researchers found microplastics in the digestive tracts of both European flounder and European smelt from the River Thames in London, with occurrence rates reflecting the fish's benthic versus pelagic feeding habits. The study demonstrates that fish in heavily urbanized river systems are exposed to microplastic contamination through their diet.
Microplastics in commercial marine fish species in the UK – A case study in the River Thames and the River Stour (East Anglia) estuaries
Researchers examined microplastic contamination in three commercially important fish species from UK estuaries, finding that over 41% of fish had ingested at least one microplastic particle. Larger and heavier fish were more contaminated, and the results highlight that humans who eat these common fish species are likely being exposed to microplastics through their diet.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
