Polyethylene terephthalate, which is used in clothing and food containers, and polyvinyl chloride (PVC), which is widespread in window frames, drainage pipes, paint and more, were also found. Researchers found that some of the plastic particles may have entered the patients during surgery. These particles, researchers said, “’cannot be attributed to accidental exposure during surgery. Plastics found in three different parts of the heart included poly(methyl methacrylate), a plastic commonly used as a shatter-resistant alternative to glass. The study also found evidence suggesting that some microplastics were inadvertently introduced to the subjects during the surgeries. Nine types of plastic were found in five types of heart tissue. They “detected tens to thousands of individual microplastic pieces in most tissue samples” and found plastic samples in all of the blood samples.
Researchers collected and analyzed the heart tissue of the patients as well as blood samples from half of the participants. Microplastics, which are less than 5 millimeters wide - or about the size of a pencil eraser, can enter the human body through the mouth, nose and other body cavities.ĭoctors Kun Hua, Xiubin Yang and their team wanted to investigate whether these particles can enter people’s cardiovascular systems through indirect and direct exposures, according to a statement about the study. The alarming find was made by a team of scientists from Beijing Anzhen Hospital in China, who analyzed the heart tissue of 15 patients who underwent cardiovascular surgery, according to the study published by the American Chemical Society. Microplastics commonly found in food packaging and paints have been discovered in the human heart for the first time. NYC plastic crackdown: Can we now get on to real issues, please?
