ClearMicroplastics and Human Health: A Comprehensive Review on Exposure Pathways, Toxicity, and Emerging Risks
This comprehensive review examines microplastic exposure pathways in humans, methods of detection, and the potential toxic effects on various biological systems. The study highlights growing evidence that microplastics can enter the body through ingestion, inhalation, and dermal contact, and may affect multiple organ systems, though significant uncertainties remain about long-term health outcomes.
Environmental exposure to microplastics: a scoping review on human health effects
This scoping review systematically examined published evidence on the health effects of microplastic exposure in humans. It found that human exposure is certain and widespread, but that data on dose-response relationships and specific health outcomes are still limited — highlighting an urgent need for rigorous human health studies.
Impact of Microplastic Exposure on Human Health: A Systematic Review of Mechanisms, Biomarkers, and Clinical Outcomes
This systematic review found that microplastics have been detected in human blood, placental tissue, and gastrointestinal samples, with proposed health mechanisms including oxidative stress, chronic inflammation, endocrine disruption, and gut microbiome alterations. While direct clinical evidence remains limited, the accumulating laboratory and observational data point to microplastics as a plausible contributor to multiple disease pathways.
The potential effects of microplastics on human health: What is known and what is unknown
This review summarizes what is currently known about how microplastics might affect human health, noting that while contamination is widespread in food, water, and air, direct evidence of harm in humans is still limited. Studies in animals and cell cultures suggest microplastics could trigger immune responses, cause inflammation, and affect reproduction and development. The authors call for more rigorous clinical studies to determine whether the levels of microplastics that people actually encounter pose real health risks.
Effects of Microplastics on Human Physiology: Mechanisms of Toxicity and Health Risks
This systematic review summarizes research on how microplastics affect human body systems, covering studies from 2000 to 2025. The evidence shows that microplastics have been found in blood, placenta, and reproductive tissues, and can trigger inflammation, oxidative stress, and immune responses. While more research is needed, the findings suggest microplastics may contribute to chronic health conditions through multiple biological pathways.
Approach to an answer to “How dangerous microplastics are to the human body”: A systematic review of the quantification of MPs and simultaneously exposed chemicals
This review found that despite extensive studies on microplastic abundance in the environment, their actual health risks to humans remain unknown due to the lack of clinical studies and standardized identification methods. The authors argue that risk assessment must account for chemicals migrating from plastic products alongside the microplastics themselves.
Health impacts of micro- and nanoplastics in humans: systematic review of in vivo evidence
This review of existing research found that tiny plastic particles (called microplastics and nanoplastics) build up in different parts of the human body and may cause inflammation and organ problems. However, the studies had different methods and limitations, so scientists can't yet prove these plastics directly cause health issues. Better long-term studies are needed to understand if microplastics - which come from things like plastic bottles and food packaging - truly harm human health.
Microplastics and Public Health
This public health paper reviewed the current state of knowledge on microplastics as an emerging health concern, covering exposure pathways, body burden, and potential disease associations. It concludes that while evidence is growing, definitive health impact data from human studies remains limited.
Systemic Accumulation and Distribution of Micro- and Nanoplastics in Human Tissues and Their Impact on Health: A Systematic Review
This systematic review synthesizes human evidence on the presence of micro- and nanoplastics in body tissues and fluids, including blood, lungs, placenta, breast milk, and liver. The research confirms that plastic particles can cross biological barriers and accumulate in multiple organ systems. While the long-term health effects are still being studied, the widespread presence of plastics inside the human body raises significant health concerns.
Harmful Effects of Microplastics and Nanoplastics in Human Body Systems: A Systematic Review
A new review of 30 studies found that tiny plastic particles called microplastics are now widespread in human bodies, showing up in blood, lungs, and other organs. Higher levels of these plastic particles were linked to more severe disease in the heart, lungs, digestive system, and reproductive organs. This research suggests that the plastic pollution around us may be harming our health, though more studies are needed to prove these plastics directly cause disease.
Possible effects of microplastics on human health
This book chapter reviews possible effects of microplastics on human health, drawing on research conducted primarily in marine and freshwater environments. It discusses how microplastics enter the human body through water, food, and air, and calls for more research to close critical knowledge gaps about long-term health consequences.
Impact of Microplastics on Human Health: A Comprehensive Review
This comprehensive review examines how microplastics enter the human body through food, water, and air, and what health effects they may cause. Researchers found evidence that microplastics can accumulate in the body and may contribute to inflammation, oxidative stress, and disruption of gut bacteria. The study suggests that more research is needed to fully understand the long-term health implications of ongoing human exposure to microplastics.
Systematic Literature Review: The Presence of Microplastics in the Body and their Impact on Human Health
This systematic review examined evidence on where microplastics accumulate in the human body and what health effects they may cause. Researchers found that microplastics have been detected in various human tissues and can enter the body through ingestion, inhalation, and skin contact. Evidence indicates that microplastics may trigger oxidative stress and inflammation, with potential effects on the digestive, respiratory, reproductive, endocrine, and nervous systems.
The current status of studies of human exposure assessment of microplastics and their health effects: a rapid systematic review
This rapid systematic review summarizes what is known about human exposure to microplastics and potential health effects based on studies published from 2000 to 2019. The researchers found that there is no standardized method for measuring microplastic exposure in humans, making it difficult to compare studies or draw firm conclusions. Despite the gaps, the available evidence suggests that people are regularly exposed to microplastics through food, water, and air, and more research is urgently needed on health effects.
Microplastics And Nanoplastics: Environmental Sources, Human Exposure Pathways, And Potential Health Impacts
This systematic review maps out the many ways microplastics and nanoplastics enter the human body, including through food, water, air, and everyday products. The researchers found these tiny particles are now present in nearly every environment, from oceans to our homes. The review highlights growing concerns about what this constant low-level exposure might mean for our long-term health.
Environmental exposure to microplastics: a scoping review on potential human health effects and knowledge gaps
This scoping review searched multiple academic databases to synthesize evidence on potential human health effects of microplastic exposure.
