Insight into microplastics in the aquatic ecosystem: Properties, sources, threats and mitigation strategies
AI summary Read the abstract
This review summarizes how microplastics contaminate aquatic ecosystems through various pathways, where they can absorb other toxic chemicals and become even more harmful. The findings are relevant to human health because microplastics in fish and shellfish from contaminated waters can carry these concentrated pollutants into our diets.
Globally recognized as emergent contaminants, microplastics (MPs) are prevalent in aquaculture habitats and subject to intense management. Aquaculture systems are at risk of microplastic contamination due to various channels, which worsens the worldwide microplastic pollution problem. Organic contaminants in the environment can be absorbed by and interact with microplastic, increasing their toxicity and making treatment more challenging. There are two primary sources of microplastics: (1) the direct release of primary microplastics and (2) the fragmentation of plastic materials resulting in secondary microplastics. Freshwater, atmospheric and marine environments are also responsible for the successful migration of microplastics. Until now, microplastic pollution and its effects on aquaculture habitats remain insufficient. This article aims to provide a comprehensive review of the impact of microplastics on aquatic ecosystems. It highlights the sources and distribution of microplastics, their physical and chemical properties, and the potential ecological consequences they pose to marine and freshwater environments. The paper also examines the current scientific knowledge on the mechanisms by which microplastics affect aquatic organisms and ecosystems. By synthesizing existing research, this review underscores the urgent need for effective mitigation strategies and further investigation to safeguard the health and sustainability of aquatic ecosystems.

Unraveling the ecotoxicological effects of micro and nano-plastics on aquatic organisms and human health
AI summary Read the abstract
This review summarizes the growing body of evidence on how micro- and nanoplastics affect aquatic organisms and, through the food chain, potentially human health. The tiny plastic particles absorb toxic pollutants and pathogens from the water, acting as carriers that deliver these harmful substances into the bodies of fish, shellfish, and other organisms. The review highlights that both direct plastic toxicity and indirect chemical exposure through contaminated seafood pose risks to human consumers.
A review of microplastics in the aquatic environmental: distribution, transport, ecotoxicology, and toxicological mechanisms
AI summary Read the abstract
This review examines how microplastics are distributed, transported, and accumulate throughout aquatic environments, and the toxicological effects they have on aquatic organisms. The study suggests that microplastics can affect human health through the food chain, but notes that understanding of combined toxicity mechanisms remains very limited. The authors identify significant knowledge gaps and call for more systematic environmental risk assessments across multiple species.
Microplastics in aquatic systems: A comprehensive review of its distribution, environmental interactions, and health risks
AI summary Read the abstract
This review summarizes how microplastics accumulate in oceans, rivers, and lakes, where they absorb toxic chemicals like heavy metals and persistent organic pollutants and carry them up through the food chain. An estimated 5.25 trillion plastic particles float in global oceans, releasing dissolved carbon that disrupts microbial ecosystems, with ultimate risks to human health through seafood consumption and drinking water.
