?microplastics have been detected in human blood.
A 2022 study published in Environment International was the first to report microplastics in human blood samples.
Microplastics were found in about 80% of the samples tested.
The detected particles included polyethylene terephthalate (PET) (used in water bottles), polystyrene (used in food packaging), and polyethylene (used in plastic bags).
Inhalation (airborne particles)
Ingestion (contaminated food or water)
Skin contact (less common, but possible through cosmetics or packaging)
Once in the bloodstream, microplastics can potentially travel to organs.
Scientists are still studying the health impacts, but concerns include:
Inflammation
Immune system disruption
Hormonal interference
Cell damage or oxidative stress
However, the field is still new, and more research is needed to understand long-term effects.
