This is the best summary I could come up with:

Microplastics have been found in every human placenta tested in a study, leaving the researchers worried about the potential health impacts on developing foetuses.

A second study revealed microplastics in all 17 human arteries tested and suggested the particles may be linked to clogging of the blood vessels.

Huge amounts of plastic waste are dumped in the environment and microplastics have polluted the entire planet, from the summit of Mount Everest to the deepest oceans.

Prof Matthew Campen, at the University of New Mexico, US, who led the research, said: “If we are seeing effects on placentas, then all mammalian life on this planet could be impacted.

He said the growing concentration of microplastics in human tissue could explain puzzling increases in some health problems, including inflammatory bowel disease (IBD), colon cancer in people under 50, and declining sperm counts.

The research, published in the Toxicological Sciences journal, found microplastics in all the placenta samples tested, with concentrations ranging from 6.5 to 790 micrograms per gram of tissue.
