What can happen when people unknowingly ingest invisible particles of plastic by eating or breathing them?
Although it is not yet clear what the effects of tiny plastic particles entering the body can be, now a possible answer has emerged.
The study, published in the journal ACS Environmental Science and Technology, found that tiny plastic particles can enter liver and lung cells and affect their function, leading to adverse health effects.
Needless to say, it is not possible to avoid plastic in our daily life, as most of the products around us are made of plastic or have plastic packaging on them.
These products emit very small plastic particles that can accidentally enter the body.
Until now, little was known about the effects of these small plastic particles on human health.
But in a recent study, experts injected plastic particles smaller than 100 nanometers in size into the blood and organs of laboratory animals, causing inflammation and neurological changes.
Considering this, the researchers decided to know the effects of small plastic particles in human lungs and liver.
For this purpose, human liver and lung cells were prepared in the laboratory and injected with plastic particles of 80 nanometers in size.
Microscopic images after 2 days showed that the plastic particles were able to enter the cells without destroying them.
To learn more about this, the researchers examined the compounds secreted by the mitochondria of these cells.
The results showed that the more plastic particles the liver and lung cells are exposed to, the greater the risk of their function being affected.
In some cases, myochondria were even observed to be inactive, and researchers said this suggests that plastic particles can damage vital organs such as the liver and lungs.
