ClearCellular and Systemic Effects of Micro- and Nanoplastics in Mammals—What We Know So Far
This review summarized known cellular and systemic effects of micro- and nanoplastics in mammals, finding that while ingestion is common, knowledge of health impacts remains limited, with oxidative stress and inflammation as the most reported biological responses.
A Systematic Review of the Toxicokinetics of Micro- and Nanoplastics in Mammals Following Digestive Exposure
This systematic review summarizes existing research on what happens to micro and nanoplastics after mammals ingest them through food and water. The evidence shows these particles can survive digestion and potentially cross into tissues and organs, raising important questions about long-term health effects from the microplastics we unknowingly consume every day.
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 review provides recommendations for improved testing methods to generate more relevant and targeted data for human risk assessment.
Micro(nano)plastics sources, fate, and effects: What we know after ten years of research
Researchers summarized a decade of advances in micro- and nanoplastic (MnP) research, documenting how these particles have been found in every environment on Earth — including air, snow, soil, and human tissue — and in thousands of species, with confirmed harmful effects. The review highlights major breakthroughs in detection methods while noting that the full scope of health impacts, especially at the nano scale, is still being uncovered.
Detection of nano- and microplastics in mammalian tissue

Research advances of microplastics and potential health risks of microplastics on terrestrial higher mammals: a bibliometric analysis and literature review
This review combines data analysis with a literature survey to map the rapid growth of microplastics research, noting a shift in focus from marine environments to land-based ecosystems and health risks in mammals, including humans. The review highlights that microplastics can accumulate in organs, trigger inflammation, disrupt hormones, and damage the gut and reproductive systems in animal studies. These findings underscore the urgency of understanding how chronic microplastic exposure may affect human health.
Current research trends on micro- and nano-plastics as an emerging threat to global environment: A review.
This review summarizes the current knowledge on micro- and nanoplastics as emerging global pollutants, covering their distribution across terrestrial, aquatic, and atmospheric environments, their persistence, and the health risks from their chemical additives. It identifies key research gaps in understanding how MNPs move between environmental compartments and accumulate in living organisms.
Animal exposure to microplastics and health effects: A review
Researchers reviewed how microplastic exposure affects animals across terrestrial and aquatic environments, finding that species suffer physical harm, chemical contamination from pollutants that stick to plastic surfaces, inflammation, and behavioral changes. Because microplastics accumulate up the food chain, the review warns that animals entering the human food supply may carry these particles into our bodies.
Health impacts of environmental contamination of micro- and nanoplastics: a review
This review summarizes the growing body of evidence on micro- and nanoplastic contamination across both marine and terrestrial ecosystems and its potential health effects. Researchers note that these tiny particles accumulate in animals along the food chain, and recent studies have detected microplastics in human stool samples, confirming human exposure through food and water. The study highlights that beyond the particles themselves, the chemical additives and pollutants that cling to plastics may pose additional health risks.
Micro(nano)plastics, an emerging health problem
This review frames micro- and nanoplastics as an emerging human health problem, synthesizing evidence of exposure routes, organ-level accumulation, and biological effects, and calling for updated regulatory frameworks to address this novel class of environmental contaminants.
Environmental Fate and Ecological Risk of Micro- and Nanoplastics across Terrestrial and Aquatic Ecosystems
Scientists reviewed existing research on tiny plastic particles (microplastics and nanoplastics) and found they're spreading throughout soil, rivers, and oceans, where animals eat them and pass them up the food chain. These plastic particles cause stress and health problems in wildlife, but researchers still don't fully understand the long-term effects or how much exposure is dangerous. This matters because these same plastic particles can end up in our food and water, but we need better research methods to understand the real risks to human health.
A systematic review of the impacts of exposure to micro- and nano-plastics on human tissue accumulation and health
This systematic review found growing evidence that micro- and nanoplastics accumulate in human tissues including lungs, gut, and blood, with lab studies showing potential disruption to immune, reproductive, endocrine, and nervous systems. The review identifies ingestion, inhalation, and dermal contact as the three main exposure routes and highlights that the smallest nanoplastic particles pose the greatest concern due to their ability to cross biological barriers.
Ecological and toxicological manifestations of microplastics: current scenario, research gaps, and possible alleviation measures
This review examines the ecological and toxicological effects of microplastics and their associated contaminants across aquatic and terrestrial environments, identifying key knowledge gaps and potential mitigation strategies. The authors emphasize that both physical particle effects and co-transported chemical pollutants pose compounding risks to wildlife and ecosystems.

Micro- and nanoplastics (MNPs) and their potential toxicological outcomes: State of science, knowledge gaps and research needs
This review summarizes what is known about the toxicity of micro- and nanoplastics in mammals, drawing from both cell studies and animal experiments. Evidence suggests these particles can cause inflammation, oxidative stress, gut disruption, and reproductive harm, with effects depending on particle size, shape, and chemical composition. However, most studies use uniform lab-made particles rather than the irregular plastics humans actually encounter, making real-world risk assessment challenging.
A review of data for quantifying human exposures to micro and nanoplastics and potential health risks
This review synthesizes data on human exposure to micro- and nanoplastics through air, water, and food, and examines the potential health effects. Researchers found evidence of respiratory, liver, immune, and gastrointestinal impacts in humans and mammals exposed to elevated plastic particle levels, with toxicity varying by plastic type and size. The study highlights that while growing evidence links plastic particle exposure to health concerns, significant data gaps remain in quantifying actual human intake and long-term risks.
