Toxic chemicals used in the production of fireproof plastic materials can be absorbed into the body through the skin via contact with microplastics, a new study from the University of Birmingham has found.
Published in Environment International , the study provides the “first experimental evidence that chemical additives in microplastics can partition into human sweat, and subsequently be absorbed through the skin into the bloodstream,” the researchers explain in a press release .

Many of the chemicals used in these products have been banned over the years, the scientists say, “due to evidence of adverse health effects including liver or nervous system damage, cancer and reproductive health risks.” But unfortunately, “these chemicals are still present in the environment in older electronic items, furnishings, carpets and building materials.”
In fact, the same team showed in a study published last year that the chemicals were absorbed into human sweat. The new research shows that “these chemicals can also be absorbed through the skin barrier into the body via sweat.”

The research used advanced 3D models of human skin as an alternative to laboratory animals and excised human tissue. The models were exposed for 24 hours to two common forms of microplastic containing polybrominated diphenyl ethers, “a chemical group commonly used as flame retardants in plastics.”
They found that “up to 8 percent of the chemical applied could be absorbed through the skin, with more highly hydrated – or sweaty – skin absorbing higher levels of the chemical.”
This means the study provides “the first experimental evidence for how this process could contribute to the body burden of toxic chemicals.”
