This review examines the environmental toxicity of emerging micro- and nanoplastics, covering their sources, degradation pathways, ecological impacts on organisms, and the need for standardized risk assessment frameworks.
Health impacts of micro- and nanoplastics: key influencing factors, limitations, and future perspectives
This review systematically analyzed how the physicochemical properties of micro- and nanoplastics — including size, shape, surface charge, and polymer type — determine their toxicological impacts across biological systems.

Impacts of Microplastics and Nanoplastics on Biota
This review examined the impacts of microplastics and nanoplastics on organisms across aquatic and terrestrial environments, finding that particle type, shape, size, and density determine environmental distribution patterns while toxicity varies widely across species and exposure conditions.
Nanoplastic toxicity towards freshwater organisms
This systematic review covers nanoplastic toxicity toward freshwater organisms, examining both conventional and bioplastic nanoplastics, and finds that size, shape, and surface chemistry all influence toxicity across a range of invertebrate and vertebrate freshwater species.
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.
Micro- and nanoplastic toxicity on aquatic life: Determining factors
This comprehensive review examined the key factors that determine the toxicity of micro- and nanoplastics to aquatic organisms. Researchers found that harmful effects depend on particle concentration, size, exposure time, shape, polymer type, and the species being exposed. The most commonly reported impacts included disrupted growth, oxidative stress, inflammation, immune system changes, and altered metabolism, with smaller particles generally causing more severe effects.
Nanoplastics impact on marine biota: A review
Researchers reviewed the emerging toxicological literature on nanoplastics in marine ecosystems, distinguishing primary nanoplastics (manufactured at nanoscale) from secondary nanoplastics (fragmented from larger debris), and summarizing how nanoscale size changes particle reactivity and bioavailability in ways that differ substantially from their macro- and microscale counterparts.
Characterization, occurrence, environmental behaviors, and risks of nanoplastics in the aquatic environment: Current status and future perspectives
This review characterized the occurrence, environmental behavior, and toxicity of nanoplastics in aquatic systems, noting that their small size gives them unique properties — including higher surface reactivity and greater bioavailability — that make them potentially more hazardous than larger microplastics, while also harder to detect.
Environmental Impacts of Microplastics and Nanoplastics: A Current Overview
This review examined the environmental impacts of microplastics and nanoplastics across ecosystems, highlighting that these tiny particles behave differently from larger plastic debris and can absorb and transport toxic chemicals. Researchers found evidence that these particles transfer through food chains from lower organisms to higher animals, including humans. The study also explored natural biodegradation processes and current efforts to reduce plastic pollution in the environment.
Ecotoxicological Impacts of Micro- and Nanoplastics in Terrestrial and Aquatic Environments
A broad review of ecotoxicological studies found that micro- and nanoplastics cause physical harm, oxidative stress, endocrine disruption, and reproductive impairment across a wide range of terrestrial and aquatic organisms, with nanoplastics generally exhibiting greater toxicity due to their smaller size and greater bioavailability.
Nanoparticles in the Environment and Nanotoxicology
This review examines the environmental fate and toxicological risks of nanomaterials, including engineered nanoparticles and microplastics/nanoplastics, as these materials are increasingly released into ecosystems. The paper surveys current understanding of nanotoxicology and highlights the potential risks that nanoparticle contamination poses to both ecological and human health.
Microplastic Pollution in the Environment
This book chapter provides an overview of microplastic and nanoplastic pollution as emerging environmental contaminants, describing their formation, persistence in the environment, pathways of biological exposure, and potential toxicity to ecosystems and human health.
A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect
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.
The Toxicity of Plastics
This review synthesized over 200 studies on plastic toxicity, examining the physical, chemical, and biological threats posed by macro- and microplastics to ecosystems and human health, including their ability to cross biological barriers and carry chemical contaminants.
Ecotoxicological and Health Impacts of Micro- and Nanoplastics
This review explores how micro- and nanoplastics affect aquatic ecosystems and potentially human health, examining toxicity mechanisms across multiple levels of biological organization. Researchers found that particle size, polymer type, and weathering influence how these contaminants cause oxidative stress, inflammation, and endocrine disruption, while the microbial communities forming on plastic surfaces may serve as reservoirs for pathogens and antibiotic resistance genes.
Ecotoxicity of Petrogenic Plastic Particles in Fish: Implication for Human Health and Environmental Risk Assessment
This review examined the ecotoxicity of petrogenic (petroleum-derived) micro- and nanoplastics on fish, covering how polymer type, size, and associated contaminants influence toxic effects. The authors discuss implications for human health risk assessment given that petrogenic MNPs are among the most prevalent plastic types in aquatic environments.
Effects of micro- and nanoplastics on aquatic ecosystems: Current research trends and perspectives
This review covers 83 studies on the distribution and toxic effects of micro- and nanoplastics in both marine and freshwater ecosystems worldwide. Researchers found that these tiny particles affected the growth, development, behavior, reproduction, and survival of a wide range of aquatic organisms. The paper identifies key research gaps and suggests future directions for understanding the full ecological impact of plastic pollution in aquatic environments.
Effects of petroleum-based and biopolymer-based nanoplastics on aquatic organisms: A case study with mechanically degraded pristine polymers
Researchers compared the toxicity of nanoplastics made from three petroleum-based plastics and one bio-based plastic (PLA) on freshwater organisms. All four types of nanoplastics caused toxic effects, but the bio-based PLA nanoplastics were not necessarily safer than conventional ones. The study suggests that switching to bio-based plastics may not eliminate the problem of nanoplastic toxicity in aquatic environments.
Micro-and Nanoplastic-Induced Biochemical Toxicity: Emerging Mechanisms and Health Risks Across Biological Systems
This comprehensive review synthesizes current understanding of how micro- and nanoplastics cause biochemical toxicity across biological systems, from plants and invertebrates to vertebrates and humans. Key mechanisms include oxidative stress, membrane disruption, immune activation, genotoxicity, endocrine disruption, and microbiome perturbation, all modulated by particle size, shape, and surface chemistry. The authors highlight critical gaps in standardization, chronic low-dose effect data, and the need for translatable biomarkers for risk assessment.

This comprehensive review analyzed 615 studies on the toxicity of micro- and nanoplastics across different polymer types, sizes, and organisms.
