ClearMicroplastics in Freshwater Ecosystems: Sources, Transport and Ecotoxicological Impacts on Aquatic Life and Human Health
This review summarizes how microplastics enter freshwater ecosystems from sources like industrial runoff, urban waste, and agriculture, and how they accumulate in sediments where aquatic organisms ingest them. Researchers found that microplastics reduce feeding efficiency, inhibit growth, and harm reproduction in freshwater species, while also acting as carriers for toxic chemicals that build up through the food chain. The study highlights the need for better waste management and further research to understand the full scope of risks to both aquatic life and human health.
Ecotoxicity of microplastics to freshwater biota: Considering exposure and hazard across trophic levels
This review examines the toxic effects of microplastics on freshwater organisms across multiple levels of the food web, from biofilms and plankton to fish and amphibians. Researchers found evidence of harm in several species, though effects varied widely depending on particle size, type, and concentration. The study highlights that freshwater microplastic toxicity is still poorly understood compared to marine environments and calls for more standardized research.
How microplastics influence the health and microbiota of aquatic invertebrates: A review
This review examines how microplastics affect the health and microbiota of aquatic invertebrates, an area that has received less attention than fish studies. Researchers summarize evidence showing that microplastics cause toxicity at biological and molecular levels, alter microbial communities associated with invertebrate hosts, and interact with climate change and other pollutants to produce combined effects. The study highlights significant knowledge gaps and proposes future research directions for understanding microplastic impacts on aquatic ecosystems.
