Tiny particles of plastic have been found for the first time in lung tissue taken from living patients, scientists from the University of Hull and Castle Hill Hospital in the UK report this in an article published in the journal Science of the Total Environment.

Scientists analyzed lung tissue samples that were collected during surgeries to treat various lung diseases at Castle Hill Hospital. A total of 13 samples were studied, with plastic particles found in 11 of them. In total, scientists identified 12 types of plastic, including those used in common household purposes - for clothing, packaging and bottles.

Microparticles were found not only at the top of the lungs, but also in the lower lungs, where, as previously thought, the airways are too narrow, which should make it difficult for the particles to enter them.

Interestingly, male patients were found to have more plastic than female patients.

According to the researchers, it is still unknown what effect microplastics may have on human health.
