Microplastics found in every human placenta tested in study (www.theguardian.com)

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.

Here's an article from 2020 about micro plastics being a carcinogen https://www.sciencedirect.com/science/article/abs/pii/S0304389420309833

Here's another that goes over individual chemicals that may leech out of them https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7068600/

That's just a few things from a search. There are already known impacts and we understand the mechanisms.

I want to begin by saying I am not dismissing concerns about microplastics in placentas. That's fucked up.

However, lots of things "are carcinogens". It's the dose that makes the poison.

[–] [email protected] 7 points 9 months ago

Yeah, and carcinogens typically screw with DNA. So even a tiny dose will cause greater impacts on a fetus both as a greater concentration than the same dose would be for an adult and as damage to DNA will replicate exponentially more times than they would in an adult.
