What Do We Know About the Microplastics Inside Us?
TL;DR
Microplastics are increasingly found in the human body, but contamination in research methods may lead to overestimated levels. Cassandra Rauert has developed a plastics-free lab to study these exposures accurately.
✦ Why It Matters
Researchers should consider redesigning their labs to minimize contamination when studying microplastics in human samples.
Key Takeaways
- Implement contamination control measures in research environments.
- Use glass and steel materials to reduce plastic exposure.
- Reassess current analytical techniques for accuracy.
- Focus on understanding health impacts of microplastics.
Full Summary
Microplastics have been detected in various environments, including oceans and food, raising concerns about their presence in humans. Cassandra Rauert, an environmental chemist, has established a plastics-free laboratory to minimize contamination during research.
She discovered that common analytical techniques for detecting microplastics in blood are prone to contamination, leading to potentially inflated results. Specifically, her research indicated that lipids in blood can produce false positives for polyethylene, a widely used plastic.
By reconstructing their lab with glass and steel materials, Rauert and her team aim to enhance the accuracy of microplastic measurements in human tissues. Accurate data is crucial for understanding the health implications of microplastic exposure, which remains largely unknown.
