ClearNanoplastic Toxicity: Insights and Challenges from Experimental Model Systems
This review summarizes what researchers have learned about nanoplastic toxicity from studies in cell cultures, aquatic organisms, and terrestrial animals. Evidence indicates that nanoplastics can be internalized by cells through various mechanisms and their toxicity depends on factors like particle size, surface modifications, and concentration. The study identifies key knowledge gaps and recommends more systematic research to better understand the health risks these particles may pose to humans.
Predicting Bioaccumulation of Nanomaterials: Modeling Approaches with Challenges
This review examines different computer modeling approaches for predicting how nanomaterials, including nanoplastics, accumulate in living organisms. Traditional models developed for dissolved chemicals often give inaccurate results for nanoparticles because they behave differently in biological systems. Newer machine learning approaches show promise for better predictions, which could help scientists estimate how much nanoplastic actually builds up in the body without needing extensive animal testing.
Nanoplastics in biological systems: What laboratory mechanisms reveal about real-world toxicity
Researchers developed a mechanistic-scaling framework reconciling high-dose laboratory toxicity data for nanoplastics with low-dose environmental realities, arguing that core injury pathways—oxidative stress, lysosomal rupture, mitochondrial dysfunction—remain active at environmental concentrations and are amplified by particle aging and co-contaminant loading.
Toxicological considerations of nano-sized plastics
This review examined the toxicological considerations specific to nanoplastics, focusing on how particle deposition in different biological compartments, physical properties (size, shape, surface chemistry), and chemical additives interact to determine biological effects. The authors argue that understanding nanoplastic toxicology requires shifting focus from exposure characterization to mechanistic biological relevance at the tissue and organ level.
Potential adverse health effects of ingested micro- and nanoplastics on humans. Lessons learned from in vivo and in vitro mammalian models
This review compiles recent studies on the effects of ingested micro- and nanoplastics using mammalian in vivo and in vitro models to assess potential human health implications. The authors found that while substantial research effort has been made, significant gaps remain in understanding absorption, biodistribution, and toxicity of these particles in mammalian systems. The review provides recommendations for improved testing methods to generate more relevant and targeted data for human risk assessment.
Single and joint exposure to nanoplastics and bisphenols: a comparative assessment of in vitro hazards
This study compared the individual and combined toxicity of nanoplastics and bisphenol compounds in biological test systems, finding synergistic effects at certain exposure combinations. The results indicate that co-exposure to these two common plastic-associated contaminants may be more harmful than either alone.
Mixtures of Micro and Nanoplastics and Contaminants of Emerging Concern in Environment: What We Know about Their Toxicological Effects
This review examines what is known about the toxicological effects of micro- and nanoplastic mixtures combined with other emerging contaminants in the environment. Researchers found that most studies fail to calculate proper interaction parameters, making it difficult to determine whether combined exposures produce additive, synergistic, or antagonistic effects on organisms.
Effects of Nanoplastics on Human Health: A Comprehensive Study
This comprehensive review examines the diverse health effects of nanoplastics, drawing on toxicology, environmental science, and epidemiology to document how these particles interact with human biological systems. The authors conclude that nanoplastics represent a growing public health concern requiring further investigation.
The toxicity of nanoparticles and their interaction with cells: an in vitro metabolomic perspective
This review examines how nanoparticles interact with human cells and cause toxic effects, using a technique called metabolomics to track changes in cell chemistry. Understanding nanoparticle toxicity is relevant to microplastic research because nanoplastics behave similarly to other nanoparticles, penetrating cells and disrupting normal metabolic processes.
Microplastic toxicity: mechanisms, assessment methods, and future research directions
This review synthesizes current knowledge on microplastic toxicity mechanisms, integrating physical, chemical, and biological pathways into a unified framework. Researchers examined assessment methods across aquatic organisms, terrestrial species, and human cell models, identifying critical knowledge gaps and recommending standardized approaches for future microplastic toxicity research.

Toxicity of gold nanoparticles complicated by the co-existence multiscale plastics.
This study examined how co-exposure to gold nanoparticles and plastic particles of different sizes modifies the toxicity of gold nanoparticles, finding complex interactions that altered toxic outcomes compared to gold nanoparticles alone. The results highlight that real-world toxicological risk assessment must account for co-contaminant interactions rather than testing pollutants in isolation.
Recent advances in toxicological research of nanoplastics in the environment: A review
Researchers systematically reviewed nanoplastic toxicology, finding that surface charge and particle size are the dominant determinants of harm — positively charged and smaller particles penetrate cell membranes more readily — and that adsorbed contaminants released inside organisms often pose greater toxicological risks than the nanoplastic particles themselves.
Reviewing nanoplastic toxicology: It's an interface problem
This review of nanoplastic toxicology argued that toxicity is fundamentally an interface problem — driven by surface properties, protein corona formation, and nano-bio interactions — and proposed mechanistic approaches borrowed from nanotoxicology to improve risk assessment frameworks.

Researchers proposed a modular and flexible risk assessment framework for evaluating the human health risks of oral exposure to micro- and nanoplastics. The framework integrates modern concepts such as Integrated Approaches to Testing and Assessment and Adverse Outcome Pathways, providing a systematic method for addressing the complexity and diversity of these materials.
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.
Distinguishing the nanoplastic–cell membrane interface by polymer type and aging properties: translocation, transformation and perturbation
Molecular simulations revealed that nanoplastic behavior at cell membranes differs significantly by polymer type and aging state, with distinct patterns of membrane translocation, transformation, and disruption. Aged nanoplastics showed altered interaction dynamics compared to pristine particles, suggesting weathering changes ecotoxicological risk.
Hazard assessment of small-size plastic particles: is the conceptual framework of particle toxicology useful?
Researchers reviewed the toxicological evidence for micro- and nanoplastic hazards using a particle toxicology framework, finding that most cell culture studies show effects only at high concentrations and that animal studies have not demonstrated overt toxicity — while concluding that realistic low-dose studies using tissue models that mimic mammalian architecture are urgently needed to properly assess human health risk.
A critical viewpoint on current issues, limitations, and future research needs on micro- and nanoplastic studies: From the detection to the toxicological assessment.
This critical review examines the current methods for detecting and characterizing micro- and nanoplastics in various environmental samples, as well as reported toxic effects from in vivo and in vitro studies. The authors found that while substantial effort has been made to understand microplastic behavior, the scientific community is still far from a complete understanding of how these particles behave in biological systems. The review calls for improved standardized protocols and more studies focused on uptake kinetics, accumulation, and biodistribution.
