P20-07 PBK-model sensitivity analysis for the biodistribution of nano- and microplastics for mice and man

The distribution of nano- and microplastics in the human body: a Hybrid Perfusion-Diffusion based PBK model

Human exposure to micro- and nanoplastics: routes, accumulation, and health implications

AI summary · Read the abstract

This review synthesizes evidence that microplastics and nanoplastics have been detected in human blood, placenta, breast milk, and stool, with emerging associations between internal MNP burdens and inflammatory, cardiometabolic, and potential reproductive effects. Humans are exposed through ingestion, inhalation, skin contact, and medical interventions, making microplastic accumulation in the body a pressing public health concern requiring urgent research into clinical health outcomes.

Pathways of human exposure to microplastics, and estimation of the total burden

AI summary · Read the abstract

Tiny plastic bits called microplastics are everywhere, in the air we breathe, the food we eat, and even things that touch our skin, and this review pulls together existing research to show we're exposed through all three routes, not just by eating contaminated food like most studies focus on. The bigger takeaway: scientists still don't have standardized, reliable ways to measure exactly how much plastic ends up in our bodies, so the true scale of our exposure remains uncertain. This matters because until better testing methods exist, it's hard to know just how much plastic we're really taking in, or what it's doing to our health.

Tracing the journey of nano- and microplastics: from environmental prevalence to human intake

AI summary · Read the abstract

This review synthesizes the sources, transport pathways, physicochemical properties, and dietary intake estimates for nano- and microplastics across environmental compartments and food categories, identifying fibers and fragments from polyethylene, polypropylene, and polystyrene as dominant forms reaching the human food chain through seafood, produce, and processed foods. Quantifying estimated daily intake across age groups and food types is essential groundwork for setting regulatory exposure limits and evaluating the cumulative health risks of microplastic ingestion.

Microplastic Pollution: Human Exposure, Uptake, Accumulation Pathways, and Potential Health Consequences

AI summary · Read the abstract

Researchers reviewed the exposure routes, uptake mechanisms, and accumulation pathways of microplastics in the human body, concluding that the ubiquitous presence of these particles warrants urgent investigation into their long-term ecological and health consequences.
