Scientists in the UK have identified microplastics for the first time in living lung tissue. The most common particles are used in plastic packaging

After Dutch scientists were the first to detect microplastics in human blood last month, British scientists have found microplastics deep in the lungs of living people for the first time in a new study, Lianhe Zaobao reported on April 6.Scientists involved in the study took tissue samples from 13 patients undergoing surgery, and 11 showed signs of microplastics, the Guardian reported.The most common particles were polypropylene, used in plastic packaging and water pipes, and Polyethylene terephthalate, or PET, used in plastic water jugs.”We didn’t expect to find high numbers of microplastic particles in deeper areas of the lungs, or to find particles of this size,” said Dr. Sadowski, one of the study’s authors from Hull York Medical School in the United Kingdom.This was surprising because the airways in the lower part of the lung are smaller, and we would have expected particles of this size to be filtered out or trapped before they could get to this depth.””This data provides an important advance in the areas of air pollution, microplastics and human health,” she said.This information can be used to create real-world conditions for laboratory experiments to determine the effects on human health.”While there isn’t enough evidence of toxicity in humans, researchers are concerned that microplastics could cause damage to human cells in workers exposed to high levels of microplastics over time.Particles of air pollution can also enter the body and cause illness for millions of people every year.
