A team of researchers from the University of Hull and Castle Hill Hospital, both in the UK, found small pieces of plastic in lung tissue taken from human life -threatening diseases, indicating the they were first seen in human diseases. The group published a paper describing their findings in the journal Environmental science.
Preliminary studies have shown that plastics of all sizes are spun in places around the world. Nowadays, studies have found small amounts of plastic in animals and humans. Such fragments are found in the spleen, spleen and liver of living and dead people. And last month a group in the Netherlands reported that microplastics were found in the bloodstream of a human health disease. In this new study, the researchers reported the presence of microplastics in lung tissue taken from living patients to a hospital.
Believing that micro-large pieces of plastic could be eaten by some people, the researchers worked with cutting teams at Castle Hill Hospital and their patients. Patients undergo surgery to treat various ailments and are allowed to have tissue removed from their lungs during the procedure to be reviewed by the research team. Under that setting, the research team was able to collect 13 samples, each of which went under a microscope. They got plastic pieces in 11 of them.
By studying plastic pieces, the researchers found 12 different types, including materials used in traditional household applications, such as clothing, bags and bottles. But the most amazing thing is where the plastic pieces are found. In addition to the upper part of the lamp, where those pieces are supposed to be collected, the group finds them in the lower parts. This is surprising because the smaller the airways in those parts of the lungs, the harder it is for the parts to reach them. Researchers are surprised to find that high levels of plastics in male patients are resistant to female patients.
The researchers note that no one really knows how small pieces of plastic will affect the bodies and health of those who have them, but it is hoped that more research will be done to find out.
