Scientists at University of Michigan found that lab gloves may be causing microplastic levels to appear higher than they actually are. Researchers recommend using cleanroom gloves to reduce contamination.

Microplastics are tiny plastic particles that can harm the environment and human health. Scientists use special equipment to analyze air, water, and other samples for these particles. But, a recent study suggests that lab gloves may be contaminating these samples and making microplastic levels appear higher than they really are.

The study found that stearates, which are not plastics but can resemble them during testing, are being transferred from the gloves to the lab tools. This means scientists may be detecting particles that are not true microplastics. The researchers recommend using cleanroom gloves, which release far fewer particles and can help reduce this contamination.

The study was led by Madeline Clough, a recent doctoral graduate at University of Michigan, along with Anne McNeil, a professor of chemistry. They published their findings in the journal Analytical Methods and received support from the University's Meet the Moment Research Initiative.

The researchers tested seven different types of gloves and found that even routine interactions with these gloves can transfer particles to the testing surfaces. On average, the gloves introduced around 2,000 false positive signals per square millimeter.

Why It Matters

This study matters because it highlights the importance of accurate data in understanding microplastic pollution. As India works to address its own plastic waste issues, this research can help scientists and policymakers make informed decisions about how to reduce microplastics in our environment.
