Could microplastics in human blood pose a health risk?

Several studies have found evidence of plastics in the human body. One revelation came after scientists detected plastic additives such as bisphenol A (BPA) and phthalatesTrusted Source in human urine. Researchers have also found microplastics in human fecesTrusted Source. However, until now, no published study has directly examinedTrusted Source the effect of these tiny plastic specks on human health. In a new study published in the journal Environment International, researchers in the Netherlands developed a method of analyzing human blood to detect microplastics. They then used this method to analyze blood from 22 healthy volunteers.

The researchers suggest several ways the plastics may have entered the bloodstream — via air, food, water, personal care products such as toothpaste and lip gloss, dental polymers, and tattoo ink residues. What happens to the microplastics once they enter the bloodstream is unclear.

In vitro studies have shown the effects of microplastics on cells. A recent study in Germany found that microplastic particles can destabilize lipid membranes — the barriers that surround all cells — which may affect their functioning. Another study found that microplastics had many effects on cells, including cell death.
