A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect
Summary
This review compares how micro-sized and nano-sized plastic particles behave differently in water environments and affect aquatic organisms. Smaller nanoplastics are generally more harmful because they can cross biological barriers, enter cells, and accumulate in tissues more readily than larger microplastics. The size-dependent differences in toxicity highlighted in this review are important for understanding which plastic particles pose the greatest risk to human health through contaminated water and seafood.
Micro and nanoplastics (MNPs) have attracted growing global research attention due to their distinct environmental impacts, addressing escalating concerns. The diverse materials, sizes, and shapes of MNPs result in a range of environmental impacts. Size, a crucial characteristic of MNPs, influences their environmental behavior, affecting processes like migration, sedimentation, aggregation, and adsorption. Moreover, size modulates the biodistribution and toxicity of MNPs in aquatic organisms. This review delves into the comprehensive impacts of plastic size, with a primary focus on environmental behavior and toxic effects. Ultimately, this review emphasizes the ecological implications of MNP size, laying a foundation for future research in this field.

Multifaceted Aquatic Environmental Differences between Nanoplastics and Microplastics: Behavior and Fate
This review argues that nanoplastics and microplastics should be treated as two distinct types of pollutants because they behave very differently in water. Nanoplastics are far more chemically reactive, can cross biological barriers more easily, and may pose greater health risks than their larger microplastic counterparts, making it important for future research to study them separately.
Toxic Effects of Nanoplastics on Animals: Comparative Insights into Microplastic Toxicity
This review compares the toxic effects of nanoplastics versus microplastics across mammals, fish, and invertebrates, finding that nanoplastics generally cause more severe harm because their tiny size allows them to cross biological barriers and enter cells more easily. In mammals, nanoplastics can cross the blood-brain barrier and cause brain inflammation, liver and kidney damage, and reproductive problems that can even pass to future generations. The findings suggest that as plastics in the environment break down into ever-smaller particles, the health risks may actually increase.
Nanoplastics in aquatic systems - are they more hazardous than microplastics?
This review evaluates whether nanoplastics — plastic particles smaller than 1000 nm — are more hazardous than microplastics, examining current evidence on their environmental concentrations, behavior, and toxicity. It concludes that nanoplastics pose distinct concerns due to greater bioavailability and cellular uptake potential, while noting that adequate standard detection methods do not yet exist.
Microplastic Particle Size Effects in Fish and Shellfish: A Review on Feeding, Digestion, Bioaccumulation, and Seafood Safety Risks
This review examines how microplastic particle size determines ingestion rates, tissue penetration, bioaccumulation, and seafood safety risks in fish and shellfish, with nanoplastics identified as the most concerning size class due to their ability to cross epithelial barriers and accumulate in internal organs.
New insights in to the environmental behavior and ecological toxicity of microplastics
This review provides new insights into how microplastics behave in the environment and their toxic effects on living organisms. Microplastics can absorb and carry other pollutants, making them more dangerous than the plastic alone, and their effects vary based on size, shape, and chemical composition. The review highlights that smaller particles, especially nanoplastics, pose the greatest risk because they can cross biological barriers and enter cells.
