Relevance of nano- and microplastics for freshwater ecosystems: A critical review

The current paper critically reviews the state-of-the-science on (1) microplastics (MP) types and particle concentrations in freshwater ecosystems, (2) MP and nanoplastics (NP) uptake and tissue translocation, (3) MP/NP-induced effects in freshwater organisms, and (4) capabilities of MP/NP to modula...

Description
Summary:The current paper critically reviews the state-of-the-science on (1) microplastics (MP) types and particle concentrations in freshwater ecosystems, (2) MP and nanoplastics (NP) uptake and tissue translocation, (3) MP/NP-induced effects in freshwater organisms, and (4) capabilities of MP/NP to modulate the toxicity of environmental chemicals. The reviewed literature as well as new data on MP and NP concentrations in the river Elbe and on particle uptake into human cells indicate an environmental relevance of small particles in the low nano- and micrometer range higher than that of larger MP. •After ingestion MP can pass the intestine without cellular uptake and tissue translocation.•Small MP and NP can be taken up by cells.•MP and NP can modulate the toxicity of chemicals.•Adverse effects in biota were rarely shown at environmentally relevant concentrations of MP.
