Microplastics in Aquatic Ecosystems
Summary
This review covers microplastic contamination in aquatic environments, examining MP sources, distribution pathways, ecotoxicological effects on aquatic organisms, trophic transfer dynamics, and the potential implications for human health through seafood consumption.
Microplastics (MPs) in the aquatic environment have emerged as a significant concern due to their potential ecotoxicological effects, trophic transfer, and potential impacts on human health. MPs have the potential to be consumed by aquatic organisms across various trophic levels, either through direct ingestion or indirectly, and subsequently transferred through aquatic food chains, resulting in diverse impacts on ecosystems and organisms. Additionally, MPs have the ability to absorb a wide range of chemical contaminants found in the environment and emit hazardous plastic additives. This chapter addresses the impact of MPs on aquatic species at various trophic stages. It also covers the impact of MPs and other contaminants on the aquatic ecosystem. We highlight ongoing research on the trophic transmission of MPs and related pollutants in the aquatic food web. In conclusion, this chapter explores the potential human health risks associated with MPs in the food chain and through dietary exposure, highlighting the need for further research, risk assessment, and mitigation strategies to protect public health.

Impact of Microplastics on AquaticOrganisms and Human Health: A Review
This review examines how microplastics from degraded plastic debris accumulate in aquatic environments, are ingested by organisms at all levels of the food chain, and may transfer to humans through seafood. The evidence warrants concern about microplastic contamination as an emerging public health issue.
Environmental and Toxicological Effects of Microplastics on Aquatic Ecosystems
This review chapter covers the environmental and toxicological effects of microplastics in aquatic ecosystems, examining their distribution in oceans, lakes, and rivers and their negative impacts on the growth, reproduction, and immune function of aquatic organisms. It also addresses the potential for microplastics to enter the human food chain through contaminated seafood.
Microplastic (MP) Pollution in Aquatic Ecosystems and Environmental Impact on Aquatic Animals
This review summarizes the current state of microplastic pollution across freshwater and marine ecosystems worldwide. Researchers found that microplastics are now virtually everywhere in aquatic environments, entering food chains through ingestion by organisms ranging from tiny invertebrates to large fish. The study highlights that microplastics also act as carriers for toxic chemicals, compounding their potential harm to wildlife and, ultimately, to people who consume seafood.
