ClearAdvancing pyrolysis-gas chromatography-mass spectrometry for the accurate quantification of micro- and nanoplastics in human blood
Researchers developed and refined pyrolysis-gas chromatography-mass spectrometry (a technique that heats plastics to identify their chemical fingerprints) to more accurately measure micro- and nanoplastics directly in human blood. Improving this method is critical because reliable detection in biological samples is a key step toward understanding how much plastic exposure humans are actually experiencing.
Quantitative analysis of microplastics in Nile tilapia from a recirculating aquaculture system using pyrolysis–gas chromatography–mass spectrometry
Researchers used a chemical analysis technique called pyrolysis-GC/MS to detect microplastics in the edible muscle tissue of farmed Nile tilapia, finding traces in 42% of fish sampled — highlighting that people who eat aquaculture fish may be ingesting small amounts of microplastics.
Microplastics in drinking water: quantitative analysis of microplastics from source to tap by pyrolysis–gas chromatography-mass spectrometry
Researchers used pyrolysis–GC-MS to quantify microplastics by mass concentration at each stage of Amsterdam's drinking water supply—from raw surface water through two treatment plants to household tap water—providing rare mass-based data on MP fate during treatment.
Response on the commentary by B. Wilhelmus, M. Gahleitner, and M. A. Pemberton, on the manuscript by M. Brits, M.J.M. van Velzen, F.Ö. Sefiloglu, L. Scibetta, Q. Groenewoud, J.J. Garcia-Vallejo, A.D. Vethaak, S.H. Brandsma, M.H. Lamoree. Quantitation of micro and nanoplastics in human blood by pyrolysis-gas chromatography–mass spectrometry: a follow-up study. Microplastics and Nanoplastics (2024) 4:12
Researchers responded to peer criticism of their study measuring microplastics and nanoplastics in human blood using pyrolysis gas chromatography-mass spectrometry, defending their methods for identifying and quantifying plastic polymers and calling for collaborative, open-minded research to advance this emerging field. The exchange highlights ongoing scientific debate about the reliability of current techniques for detecting nanoplastics in human tissues.
