Py-GC/MS Data of Microplastic Detection in Human Atherosclerotic Plaque
AI summary Read the abstract
Researchers applied pyrolysis-gas chromatography-mass spectrometry to detect microplastics directly in human atherosclerotic plaque tissue, comparing a direct measurement approach against an enzyme-alkali digestion pretreatment protocol to evaluate which method better recovers polymer signatures from this complex biological matrix.

Py-GC/MS Data of Microplastic Detection in Human Atherosclerotic Plaque
AI summary Read the abstract
Researchers compared direct pyrolysis-GC/MS measurement against a tailored enzyme-alkali digestion pretreatment protocol for detecting microplastics in human atherosclerotic plaque, evaluating which sample preparation approach yields more reliable polymer identification in calcified tissue.
Microplastics in three types of human arteries detected by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS)
AI summary Read the abstract
Researchers detected microplastics in all 17 human artery samples tested, including coronary arteries, carotid arteries, and the aorta. Arteries with atherosclerotic plaques (hardened, narrowed areas) contained significantly more microplastics than plaque-free arteries. This suggests that microplastic accumulation may be associated with atherosclerosis, the buildup of fatty deposits in arteries that is a leading cause of heart attacks and strokes.
Microplastics Identification by Pyrolysis Gas Chromatography Mass Spectrometry (py-GCMS)
AI summary Read the abstract
This paper reviews pyrolysis gas chromatography mass spectrometry (Py-GC/MS) as a method for identifying and quantifying microplastics in environmental samples. The technique can identify specific polymer types even in complex environmental matrices where visual identification is difficult.
Abstract Number: Esoc2026a964 Microplastics Not Detected in Cerebral Thrombi from Cardioembolic Stroke: Detection Using Pyrolysis–gc/ms
AI summary Read the abstract
Using pyrolysis-GC/MS — a more chemically rigorous method than visual inspection — researchers analyzed clot material retrieved during mechanical thrombectomy from cardioembolic stroke patients and found no detectable polyethylene, polystyrene, or other plastic polymers, urging caution in interpreting earlier reports of microplastics in cardiovascular tissue.
Advancing microplastic analysis: Pyrolysis-GC-MS method development and validation for small polymer particles in complex environmental matrices
AI summary Read the abstract
Scientists developed a more precise lab method to detect and measure tiny plastic particles (microplastics) hiding in soil and river water, testing it on real samples from grasslands and rivers. They found measurable levels of several plastic types, including PVC and polyethylene, in both environments, a reminder that microplastics are widespread in the ecosystems that produce our food and water. Better detection tools like this one are a key step toward understanding how much plastic pollution we're actually exposed to and what risks it might pose to our health.
