In recent years, researchers have been uncovering the presence of microplastics in various environmental mediums such as food, water, and air. These tiny plastic particles present challenges for identification due to their small size and prevalence everywhere, causing the potential for contamination during research.

A study conducted by chemists at the University of Michigan revealed that environmental microplastic measurements could be contaminated by lab gloves, leading to inflated numbers of microplastics in the air. The team found that particles from the gloves, specifically stearate salts, were mistakenly identified as microplastics due to their structural similarities to polyethylene.

Further investigation showed that using various types of gloves in the lab could contribute significant amounts of misidentified particles, potentially skewing the results. The contamination, especially with particles smaller than 5 um, could impact human health and ecosystem health by misrepresenting the actual abundance of microplastics.

To address this issue, the researchers recommend avoiding glove use in microplastic research or opting for gloves without stearates. They have developed methods to differentiate between microplastics and glove residue in datasets. Despite setbacks in their initial data, the team plans to continue their research on atmospheric microplastic contamination in Michigan without the use of gloves.

While the actual prevalence of microplastics in the environment may be lower than previously thought, any amount can still pose risks to human health and ecosystems. The findings from this study highlight the importance of careful handling in microplastic research to ensure accurate results and inform future policies and regulations.
