Microplastic contamination located deep in the lungs of living people was found for the first time in almost all samples analyzed by the researchers.
Samples were taken from 13 patients who would undergo surgery and contamination was found in at least 11 of them, according to the report published by e the British daily The Guardian.
The study showed that the most common plastics were those used in packaging, tubes and bottles.
The results were similar to the numerous microplastics found in the human body during autopsies.
It has been known before that humans are in contact with plastic waste but those that end up in his stomach, as happens when taken from water or food, are much less harmful than those taken from the air and remain in the lungs.
Numerous microplastics were first identified in human blood in March last year, indicating that they can travel through the body and then be implanted in human organs.
This is a relatively new phenomenon and its consequences are not officially recognized.
But researchers worry that these microparticles damage human cells and can cause millions of deaths each year.
“We did not expect to find such a large number of particles in the lower part of the lungs,” said Laura Sadofsky of Hull University in the United Kingdom. “It’s strange that they are smaller at the bottom where we thought they would be filtered or left somewhere before they got that deep.”
“The data is a serious advancement in air pollution and human health,” she added.
The rude study was accepted for publication in the journal Science of the Total Environmentand analyzes particles up to 0.003mm that by spectroscopy study the type of plastic as well as the level of pollution of their environmental background.
