Behavioural Mechanisms of Microplastic Pollutants in Marine Ecosystem: Challenges and Remediation Measurements
AI summary Read the abstract
Microplastics in marine ecosystems cause wide-ranging harm to aquatic organisms, including genomic instability, oxidative stress, and disruption of normal physiology across oceans, lakes, rivers, and coastal zones. Understanding the behavior and toxic mechanisms of microplastics is essential for developing effective remediation strategies to protect marine biodiversity.
Plastic pollution is the biggest threat to marine ecosystem owing to its high rates of disposal and low recovery from the environment. Due to inefficiency in degradation, most of plastic is fragmented into microplastics that are reported as ubiquitous toxicants in marine environment. The abundance of toxic microplastics in marine ecosystem causes adverse impacts on aquatic flora and fauna including oceans, lakes, rivers, coastal areas, and seas. This aggravates its toxicity and induces genomic instability, oxidative stress and disruption of marine organisms. Hence, it is necessary to understand the potential sources, types and behaviour of microplastic in marine environment. In this review, considering the pollution of aquatic ecosystem, major contributors of microplastics in marine environment along with their classification are brought out. Also, behaviour mechanisms of microplastics including physical, chemical and biological behaviours together with their ecological and toxicological impacts on marine ecosystem are illustrated. Finally, the remediation measures to combat against toxic microplastic pollution in aquatic ecosystem are highlighted to bring out an instant remedy for the environment.

Microplastic Pollution in Marine Ecosystem and Its Remediation
AI summary Read the abstract
Researchers reviewed the sources, distribution, and remediation strategies for microplastic pollution in marine ecosystems, tracing the escalating environmental burden from decades of unchecked plastic production. Marine microplastics are ingested by a wide range of species across trophic levels, creating bioaccumulation pathways that ultimately deliver plastic particles and their associated chemical contaminants to seafood consumed by humans.
Microplastics in the Marine Ecosystems: Identification and Impacts
AI summary Read the abstract
Tiny plastic particles called microplastics, broken-down bits of everyday plastic waste, are showing up along India's coastlines, and this review paper rounds up what scientists have found so far. While research on their health effects is still catching up, these particles are known to persist in the environment and can enter the food chain through seafood, raising concerns about long-term exposure for coastal communities. The authors point out that India still needs a lot more research to fully understand how serious this problem is and what it means for people's health.
Microplastics as Pollutants in the Marine Environment
AI summary Read the abstract
Researchers reviewed the pathways and consequences of microplastic pollution in marine environments, focusing on how post-consumer plastic waste breaks down and accumulates across ocean ecosystems. The review underscores the widespread ecological risks posed by microplastics to marine life, with potential implications for human health through seafood consumption.
The effects of microplastics on marine ecosystem and future research directions
AI summary Read the abstract
Researchers summarize how microplastics accumulate throughout marine food webs and affect growth, behavior, reproduction, and survival of marine organisms, while calling for standardized testing methods and greater focus on fiber and fragment morphologies to better quantify real-world ecological risks.
Microplastic Fate and Impacts in the Environment
AI summary Read the abstract
Microplastic pollution has been documented across virtually every ecosystem on Earth — from ocean surfaces to deep-sea floors, polar regions to tropical soils, and in organisms spanning the full breadth of the food web. This pervasive distribution confirms that microplastic exposure is now universal and that understanding long-term fate and biological impacts is one of the most pressing environmental health challenges of our time.
