Study Reveals Lab Gloves Contaminate Samples with Microplastics

Summary

Story summary

Researchers at the University of Michigan found that lab gloves shed microplastic-like particles, contaminating samples.
The soap-like residue used in glove manufacturing produces vibrational signatures similar to plastics, inflating data, per Analytical Methods.
Madeline Clough, a doctoral graduate, recorded plastic counts over 1,000 times higher than expected, attributing contamination to stearate-coated gloves.
The study recommends using cleanroom gloves without stearate coatings and notes a possible reevaluation of years of data.
