ClearDetection of nano- and microplastics in mammalian tissue
Researchers detected nano- and microplastics in mammalian tissue samples using sensitive analytical techniques, confirming particle accumulation in organs beyond the gastrointestinal tract. The findings demonstrate that small plastic particles can translocate from the gut to systemic tissues.
Morphological and chemical characterization of nanoplastics in human tissue
Researchers developed methods to visualize and chemically characterize nanoplastics that have accumulated in human tissue samples. They were able to identify plastic particles smaller than one micrometer within tissue using advanced microscopy and spectroscopy techniques. The study provides some of the first direct evidence of nanoscale plastic accumulation in the human body, which is essential for designing future health effects research.
Effects of Microplastics on the Human Body and Methods of Detection
This review summarized how microplastics and nanoplastics enter the human body through ingestion, inhalation, and skin contact, and outlined current detection methods used to identify them in biological samples. The authors found that while evidence of tissue accumulation is growing, health effect thresholds and standardized exposure metrics are still lacking.
Methods for the detection of microplastics in mammals
Scientists now detect microplastics in human blood, lungs, placentas, and other tissues, but the field still lacks a single gold-standard method for measuring them. This review compares the strengths and limitations of current detection techniques — including spectroscopy, microscopy, and chemical digestion — to help standardize how microplastics in the human body are quantified, which is a prerequisite for accurately assessing health risks.
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.
Microplastics and Nanoplastics in human tissues: Systematic review of evidence, analytical protocols, and methodological challenges
This systematic review pulls together evidence on microplastics and nanoplastics found in human tissues like lungs, liver, and placenta. It confirms that tiny plastic particles are accumulating in our bodies, though detection methods still vary widely between studies, making it hard to compare results.
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.
Detection of microplastics in human tissues and organs: A scoping review
This scoping review summarizes studies that have detected microplastics in various human tissues and organs. The review found that microplastics enter the body through multiple routes and have distinct characteristics depending on where they accumulate. The variety of analytical techniques used across studies makes direct comparisons difficult, highlighting the need for standardized methods.
Detection and Fate of Microplastics and Nanoplastics and Technologies for Their Removal
This review covers the detection, environmental fate, and removal technologies for microplastics and nanoplastics across aquatic, terrestrial, and atmospheric ecosystems. Researchers summarize the current understanding of how these particles are distributed in environmental matrices and biota, from marine organisms to human tissues. The study highlights both the scale of the contamination problem and the emerging technologies being developed to address it.
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.
Exposure and Health Effects of Microplastics in Humans
