microplastics have been detected in human blood.
Key findings:
-
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).
How do microplastics enter the blood?
-
Inhalation (airborne particles)
-
Ingestion (contaminated food or water)
-
Skin contact (less common, but possible through cosmetics or packaging)
Why is this concerning?
-
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.
