Episode notes
Flaws in Plastic Detection Method
- Pyrolysis gas chromatography mass spectrometry burns brain tissue to detect plastics in the resulting gas.
- However, this method can mistake brain fat for plastic because their breakdown products look very similar.
Contamination Risks in Plastic Studies
- Contamination is a major challenge when detecting microplastics in human tissue samples.
- Plastic particles could enter samples from lab equipment or handling rather than the human body itself.
Microplastics Amounts Are Tiny
- Studies using other techniques find microplastics in human tissues but in very small amounts.
- The total plastic in the body is likely a tiny, invisible particle, not a significant mass like a plastic spoon.
