Environmental and Toxicological Effects of Microplastics on Aquatic Ecosystems
Summary
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.
Plastic pollution is one of the most significant environmental challenges facing the world today. The massive amount of plastic waste generated by human activities is causing severe damage to ecosystems and posing a threat to human health. In recent years, microplastics (MPs) have emerged as a major concern in the field of environmental science and have been found to be present in various aquatic environments, including oceans, lakes, and rivers. MPs are tiny plastic particles with a diameter of less than 5 mm, and they are widely present in water bodies. They can be produced through the breakdown of larger plastic items or as a result of various industrial processes. Due to their small size, MPs can easily enter the food chain and cause severe harm to aquatic organisms. The toxicological effects of MPs on aquatic ecosystems are a growing concern, as research has shown that they have negative impacts on the growth, reproduction, and immune systems of aquatic organisms. Furthermore, MPs can also absorb and release harmful substances such as heavy metals and organic pollutants, further polluting the water. This chapter aims to provide a comprehensive overview of the issue of MP pollution in aquatic ecosystems, including its sources, presence, behavior, impacts, and mitigation measures. It is hoped that this chapter will help to raise awareness of the severity of the problem and provide valuable insights into how we can work together to address this global environmental challenge. In conclusion, MP pollution is a complex and urgent problem that requires immediate attention and action from individuals, governments, and industries alike. By working together, we can reduce the amount of plastic waste generated and prevent further harm to our environment and the organisms that inhabit it.

This review examines the impacts of microplastics on freshwater ecosystems and human food chains, tracing how plastic particles enter rivers and lakes, accumulate in fish and invertebrates, and transfer to humans through consumption of contaminated freshwater species.
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.
