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
AI summary Read the abstract
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.
This review aims to facilitate future research on microplastics (MPs) in the environment using systematic and analytical protocols, ultimately contributing to assessment of the risk to human health due to continuous daily exposure to MPs. Despite extensive studies on MP abundance in environment, identification, and treatment, their negative effects on human health remain unknown due to the lack of proof from clinical studies and limited technology on the MP identification. To assess the risk of MPs to human health, the first step is to estimate MP intake via ingestion, inhalation, and dermal contact under standardized exposure conditions in daily life. Furthermore, rather than focusing on the sole MPs, migrating chemicals from plastic products should be quantified and their health risk be assessed concurrently with MP release. The critical factors influencing MP release and simultaneously exposed chemicals (SECs) must be investigated using a standardized identification method. This review summarises release sources, factors, and possible routes of MPs from the environment to the human body, and the quantification methods used in risk assessment. We also discussed the issues encountered in MP release and SEC migration. Consequently, this review provides directions for future MP studies that can answer questions about MP toxicity to human health.

Microplastics and Human Health: A Comprehensive Review on Exposure Pathways, Toxicity, and Emerging Risks
AI summary Read the abstract
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.
Microplastics and Their Human Health Effects - Systematic Review of Systematic Reviews in Research of Microplastics
AI summary Read the abstract
This systematic review of systematic reviews provides an overview of what is known about microplastics and human health. The research found that while microplastics are confirmed to be present in the human body, the specific health effects linked to different plastic types remain poorly understood. The study highlights that this field is still young and calls for more research to clarify the true health risks of daily microplastic exposure.
Microplastics and nanoplastics in humans: exposure pathways, biological mechanisms, and implications for health risk assessment
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics are everywhere—in our air, food, and water—and this review pulls together existing research on how they might get into our bodies and affect our health, including triggering inflammation, disrupting gut bacteria, and interfering with hormones. The bigger takeaway is that scientists still don't have solid answers on how much exposure is actually harmful or which groups (like children or people with existing health conditions) might be most at risk. This matters because it means current safety guidelines are based on incomplete information, so more research is needed before we can say how worried we should really be.
The potential effects of microplastics on human health: What is known and what is unknown
AI summary Read the abstract
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.
The current status of studies of human exposure assessment of microplastics and their health effects: a rapid systematic review
AI summary Read the abstract
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.
