Scare the baby to death! The first discovery of microplastics in human breast milk

  • 2022-10-11
Scientists found microplastics in human breast milk for the first time. Since infants are vulnerable to chemical pollutants, further research is needed to identify potential health risks.

Researchers from Italy's Marche University of Technology collected breast milk samples from 34 women who had just given birth for a week and were in good health. Microplastics were detected in 75% of the samples. This study was published in the British chemical journal POLYMER. So what is micro plastic? Microplastics are plastic particles smaller than 5mm in size. They may come from various sources, including cosmetics, detergents, packaging, and even synthetic fibers on clothes. Because they exist in all water bodies today, including bottled water and tap water, fish are also consuming them. They are part of our food supply. Micro plastics enter the human body mainly through ingestion, inhalation and skin contact. Once internalized, microplastics can pass through the cell membrane and transfer to different parts of the body, triggering specific cellular mechanisms. The most abundant microplastics are composed of polyethylene, polyvinyl chloride and polypropylene, with sizes ranging from 2 to 12 µ m. Previous studies have shown that infants fed with milk bottles may swallow millions of microplastics every day, and the concentration of microplastics in infant feces is 10 times that of adults.
