ClearFate of Micro/Nano Plastic Pollutants in the Marine Ecosystem
This review traces the journey of micro- and nanoplastics through marine ecosystems, from their release as industrial wastewater to their accumulation in organisms via bioaccumulation and food web transfer. Once in the ocean, these particles undergo processes like biofouling and fragmentation that change their behavior and toxicity, and they act as carriers for other persistent pollutants and pathogens. The paper underscores that marine plastic pollution is not static but dynamic, with evolving risks at every level of the food chain including seafood consumed by humans.
Impact of Micro and Nano Plastics on Ocean Environment
This review examines the impacts of micro- and nanoplastics on ocean environments, covering their sources, fragmentation from larger plastic debris, effects on marine species across the food chain from plankton to fish, and implications for ocean ecosystem health.
Fate of plastics and microplastics in the marine environment
This thesis reviewed how plastics and microplastics enter, move through, and accumulate in marine environments, examining sources, transport pathways, and long-term fate. Understanding the ocean's plastic burden is essential for predicting ecological and human health risks.
Micro- and nano-plastics in marine environment: Source, distribution and threats — A review
This review examines the sources, distribution, and threats of micro- and nanoplastics in the marine environment. Researchers found that microplastics are nearly ubiquitous in ocean ecosystems, causing harm to marine animals ranging from malnutrition to chemical poisoning. The study also highlights that nanoplastics can penetrate biological barriers, including the gastrointestinal and blood-brain barriers, and accumulate in vital organs.
Microplastics in the Marine Environment: A Review of Their Sources, Formation, Fate, and Ecotoxicological Impact
This review collates evidence on microplastics in the marine environment, covering primary and secondary sources, degradation pathways into particles under 5 mm, ecotoxicological effects on marine biota that ingest smaller particles, and the transport and deposition mechanisms governing microplastic fate in sediments, shorelines, and the deep sea.
Microplastic and nanoplastic pollution: Assessing translocation, impact, and mitigation strategies in marine ecosystems
This review examines how microplastics and nanoplastics move through marine ecosystems, contaminating species from tiny plankton to large fish through processes like biofouling and chemical leaching. The plastics interact with other environmental stressors like climate change and chemical pollution, compounding their effects on marine food webs. The authors highlight that nanoplastics, which form as microplastics break down further, may pose additional unique risks that are not yet well understood.
Microplastics and Nanoplastics in Aquatic Environment
This review examines the origins, transport pathways, and toxic impacts of microplastics and nanoplastics in aquatic environments, tracing debris from diverse land-based and marine sources. Researchers found that plastic fragmentation produces ubiquitous micro- and nano-scale particles throughout ocean systems, with documented toxicity to marine organisms and potential risks to human consumers of seafood.
Microplastics and Nano-Plastics: From Initiation to Termination
This review traced the lifecycle of micro- and nanoplastics from their formation through environmental transport to potential remediation, highlighting ecotoxicological effects on marine ecosystems and the global push toward sustainable plastic management.

This review summarized global research on microplastic distribution, accumulation, and biological effects in ocean environments, covering transport mechanisms from surface to deep sea, ingestion across the food web, and evidence for physical and chemical toxicity to marine organisms.
The Environmental Impacts of Nanoplastics in Marine Ecosystems
This review examined how nanoplastics—generated by degradation of larger plastics—penetrate biological barriers, accumulate in tissues, contribute to biomagnification, and disrupt marine food chains, highlighting their distinct ecotoxicological mechanisms compared to larger microplastics.
Sources, Fate, and Impact of Microplastics in Aquatic Environment
This review summarizes the sources, transport pathways, fate, and ecological impacts of microplastics in aquatic environments, noting that coastal areas have the highest concentrations but that microplastics sink and accumulate in deep sediments after fragmentation. The pervasive contamination of aquatic ecosystems poses threats to marine biota and food webs that ultimately affect human health.
