Scientists looked for tiny plastic bits in human vein tissue, but found that the gloves they wore left behind chemicals that look like plastic under special lights.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

In 2020, researchers found that gloves used in labs introduced a chemical called stearate into samples, which interfered with the detection of microplastics in scientific studies.
Microplastic particles were found in human vein tissue samples at low levels, but the amounts were similar to those found in control samples used during testing, indicating they likely came from laboratory or environmental exposure rather than from inside the body.
Certain chemical compounds used in food and consumer products have been found in human vein tissue, suggesting these substances may not be fully broken down during digestion. Their presence could interfere with scientific efforts to detect plastic particles in the body.
In microplastic research, scientists use blank samples to tell the difference between microplastics that came from the environment and those that were actually present in tissue, because blank samples often have similar numbers of particles but different types of plastic.
The stearate coating on some gloves creates an infrared signal that matches polyethylene plastic, which can cause laboratory instruments to incorrectly detect microplastics in samples where none are present.
