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.

    mainly curious about the dialysis. i feel the passive elimination would vary based on demographic, intake, diet etc. i guess you would just need something semipermeable that traps the plastics. trapping plastic with plastic

      Well now I can’t find whatever I was looking at that said it was effective. But I did find this: https://www.sciencedirect.com/science/article/pii/S2666821123000868

      Obviously, hydrogen peroxide would not be a good idea in hemodialysis, but some of the other reactants might be useful.

      Since microplastics are a bit larger than blood cells (plastics 10-50um vs white blood cells 12-15 and red 7.5-8.7um) theoretically they could be filtered by a 15um water filter to get most of them.
