A new laboratory technique has been developed that can detect extremely small amounts of polypropylene plastic particles in human blood, down to 14 nanograms per milliliter, which was not possible...

Synthesis from 1 study
This method doesn't change anything in the body—it just finds tiny plastic bits in blood that were too small to see before. It heats the blood to break plastics into recognizable chemical pieces, separates them cleanly, and reads their unique molecular patterns with extreme precision, while making...
Most probable mechanism
A highly precise lab method breaks down plastic particles into identifiable chemical fragments, separates them from blood components, and detects even the tiniest amounts by matching their unique molecular fingerprints, allowing scientists to see plastics that were too small or too rare to find before.
Polypropylene particles in blood are thermally decomposed into volatile organic fragments through controlled pyrolysis.
The resulting chemical fragments are separated by gas chromatography based on their molecular weight and polarity.
Fragment ions are ionized and sorted by mass-to-charge ratio using full-scan mass spectrometry to generate a comprehensive molecular profile.
Rigorous contamination controls eliminate background interference from environmental plastics, ensuring detected signals originate solely from blood samples.
The system's signal-to-noise ratio is optimized to detect molecular fragments at concentrations as low as 14 ng/mL for polypropylene and 48 ng/mL for polypropylene.
