Microplastics contamination in marine system
Summary
This review examines the sources, distribution, and ecological impacts of microplastic pollution in marine environments, from coastal waters to the deep ocean. Researchers found that microplastics are frequently mistaken for food by marine organisms, leading to ingestion that can cause physical harm and facilitate the transfer of toxic chemicals. The study underscores the need for better waste management and policy interventions to protect marine ecosystems.
Microplastic pollution is a worldwide problem that negatively impacts the marine ecosystem's food supply. Their highest concentrations are found in mid-ocean gyres and along coastal lines. Because they frequently have sizes that are similar to those of prey as well as are mistaken for food, microplastics pose a threat to marine life. When consumed, may cause a variety of harmful effects on marine life, which could make it easier for hydrophobic contaminants to find their way into aquatic environments . This chapter explains the effects of microplastic pollution on both humans and marine organisms. Various studies have shown that eating microplastics has caused fish to ingest chemical toxins, which can harm their digestive systems, choke marine life, serve as a pathway for the spread of bacteria, and reduce their ability to grow and reproduce. Fish and human survival are more at risk as a result of these threats. Marine scientists have thus found it necessary to spread awareness to the public about the risks associated with using products that endanger the health of marine organisms as well as the ecosystem. Further, we have discussed gathering and assessment of marine microplastics, analytical approaches for the characterization of microplastics, control of microplastic contamination in marine ecosystems , and techniques for the separation of microplastics from the marine environment. This chapter will help the researchers working on microplastic pollution, its control, and its effects on marine systems along with human health.

Understanding microplastic pollution of marine ecosystem: a review
This review summarizes the current understanding of microplastic pollution in oceans, covering where they come from, how they spread, and their harmful effects on marine life and potentially human health. Microplastics are found throughout the ocean -- from surface waters to deep sediments -- and can transfer toxic chemicals to organisms that consume them. The authors highlight that significant gaps remain in detection methods and understanding the full scope of how marine microplastics affect the food chain that leads to our plates.

Microplastics as contaminants in marine environment.
This review summarizes the sources, distribution, and environmental impacts of microplastics in the marine environment, covering how they enter the ocean, where they accumulate, and what harms they cause to marine organisms. It also discusses the potential for microplastics to transfer up the food chain to humans through seafood.
