You Know How Scientists Keep Finding Microplastics Literally Everywhere? Well, You'd Never Guess What Their Lab Gloves Are Coated in Straight Out of the Packaging

Key Points:

Researchers from the University of Michigan have discovered that coatings on nitrile and latex gloves, specifically stearates used to aid glove removal, can contaminate samples and inflate measured microplastic levels in environmental studies.
The chemical similarity between stearates and microplastics makes it very difficult to distinguish between them in laboratory analyses, potentially skewing previous research findings on microplastic contamination.
Testing revealed that cleanroom gloves, which lack stearate coatings, contribute significantly less contamination, suggesting that glove choice is critical in microplastic research to avoid overestimation.
The study highlights the need for improved methodologies and contamination controls in microplastic research and offers spectral libraries of stearate standards to help correct affected datasets.
Despite these challenges, researchers emphasize that microplastics should ideally be absent from the environment and call for continued rigorous scientific efforts to accurately assess their presence and impact.
