Microplastics: Found in Every Human Placenta Tested, Health Impacts, Arteries, PVC
- Microplastics found in every human placenta tested in study, The Guardian, Feb. 27, 2024. Ed. - Scientists express concern over health impacts, with another study finding particles in arteries
Microplastics have been found in every human placenta tested in a study, leaving the researchers worried about the potential health impacts on developing foetuses. The scientists analysed 62 placental tissue samples and found the most common plastic detected was polyethylene, which is used to make plastic bags and bottles. A second study revealed microplastics in all 17 human arteries tested and suggested the particles may be linked to clogging of the blood vessels.
Microplastics have also recently been discovered in human blood and breast milk, indicating widespread contamination of people’s bodies. The impact on health is as yet unknown but microplastics have been shown to cause damage to human cells in the laboratory.
The particles could lodge in tissue and cause inflammation, as air pollution particles do, or chemicals in the plastics could cause harm.
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. People are known to consume the tiny particles via food and water as well as breathing them in, and they have been found in the faeces of babies and adults.
Prof Matthew Campen, at the Univ. of New Mexico who led the research, said: “If we are seeing effects on placentas, then all mammalian life on this planet could be impacted. That’s not good.” 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...

- PVC, a synthetic resin made from the polymerization of vinyl chloride. Second only to polyethylene among the plastics in production and consumption, PVC is used in an enormous range of domestic and industrial products, from raincoats and shower curtains to window frames and indoor plumbing. A lightweight, rigid plastic in its pure form, it is also manufactured in a flexible “plasticized” form...
