ClearFeasibility of Raman and FTIR spectroscopy for direct microplastic search in the human milk samples: Comparative qualitative study
Researchers tested whether infrared and Raman spectroscopy could detect microplastics directly in human breast milk without harsh chemical processing that might damage the samples. They found these methods can serve as a useful screening tool for common plastics like polyethylene and polystyrene in milk, which matters because breast milk is a direct route of microplastic exposure for infants.
Isolating microplastics from human milk: a chemical digestion approach for effective polymer extraction and ATR-FTIR analysis
Researchers developed and evaluated a chemical digestion method for isolating microplastics from human breast milk, addressing the challenges posed by the high fat and protein content of this matrix. The method enabled ATR-FTIR polymer identification of MPs extracted from milk samples, providing a validated protocol for studying infant dietary MP exposure.
Raman Microspectroscopy Detection and Characterisation of Microplastics in Human Breastmilk
Researchers used Raman spectroscopy to detect and characterize microplastics in human breast milk samples for the first time. They found microplastic particles in the samples, confirming that nursing infants can be exposed to microplastics through breastfeeding. This pilot study highlights the need for larger investigations into how microplastics in breast milk might affect infant health during a critical period of development.
Detection of Microplastics in Human Breast Milk and Its Association with Changes in Human Milk Bacterial Microbiota
Researchers detected microplastics in nearly 39% of breast milk samples from 59 mothers, with polypropylene and polyethylene being the most common types found. The presence of microplastics was linked to changes in the bacterial makeup of breast milk, raising concerns about early-life microplastic exposure in infants during breastfeeding.
Analisis Mikroplastik Pada Botol Susu Plastik Bayi Dengan Metoda FTIR
This Indonesian study analyzed baby bottle plastics using infrared spectroscopy to detect microplastics released during use. Plastic baby bottles are a known source of microplastic exposure in infants, and identifying the specific polymer types released helps characterize the nature and potential risks of this common exposure.
Detection of microplastics in human lung tissue using μFTIR spectroscopy
Researchers analyzed lung tissue from 13 people and found microplastics in 11 of the samples, identifying 12 different plastic types including polypropylene and polyester. The particles were found in all regions of the lungs, with significantly higher concentrations in the lower lung. This is one of the first studies to directly confirm that microplastics from everyday environments can be inhaled and accumulate deep in human lung tissue.
Microplastics in human blood: Polymer types, concentrations and characterisation using μFTIR
Scientists analyzed blood from 20 healthy volunteers and found microplastics in 90% of samples, identifying 24 different plastic types including many reported for the first time in blood. The particles were mostly small fragments averaging about 128 micrometers long, and the study also detected hormone-disrupting chemicals called phthalates attached to the plastics. This adds to growing evidence that a wide variety of plastic particles are circulating in human blood.
Release of microplastics from breastmilk storage bags and assessment of intake by infants: A preliminary study
Researchers tested six commercially available breastmilk storage bags and found they released large numbers of microplastic and submicron particles during simulated normal use. The particles were identified as plastics using spectroscopy analysis, raising questions about infant exposure through stored breastmilk. The study suggests that single-use plastic baby food packaging may be an overlooked source of microplastic ingestion for infants.
Contributions of Fourier transform infrared spectroscopy in microplastic pollution research: A review
This review covers advances in Fourier transform infrared (FTIR) spectroscopy techniques — including chemical imaging — for identifying polymer types in microplastic samples and tracing their fate in different environmental matrices.
Harmonizing infrared spectroscopic techniques for microplastic identification: a comparative evaluation of ATR and µFTIR transmission and reflection modes
Researchers systematically compared the performance of Attenuated Total Reflectance (ATR) and micro-Fourier Transform Infrared Spectroscopy (muFTIR) in both transmission and reflection modes for identifying microplastics from twelve common real-world plastic products, providing guidance on optimizing spectroscopic technique selection.
Evaluation of near infrared spectroscopy for direct detection of common microplastics contamination in camel Milk powder
Researchers evaluated near infrared spectroscopy as a rapid, non-destructive method for detecting common microplastic contamination in camel milk powder. The technique successfully distinguished between uncontaminated and contaminated samples spiked with polyethylene, polypropylene, polystyrene, and PET at concentrations as low as 0.01% by weight. The findings suggest NIR spectroscopy could serve as a practical quality control tool for screening microplastic contamination in premium dairy products.
Microplastics in human urine: Characterisation using μFTIR and sampling challenges using healthy donors and endometriosis participants
Researchers analyzed urine samples from healthy individuals and endometriosis patients, detecting microplastics in the majority of both groups, with 22 different polymer types found. While microplastic levels were not significantly different between the two groups, the finding that plastics like polyethylene, polystyrene, and PTFE are being excreted in human urine confirms that these particles are circulating through the body.

This review evaluates cutting-edge infrared spectroscopy techniques for detecting and analyzing micro- and nanoplastics in environmental and food samples. Better detection methods are crucial for understanding human exposure because they allow scientists to measure smaller particles more accurately, including nanoplastics that are small enough to cross biological barriers and accumulate in human tissues.
