Surgeons have found microplastics within the human heart, raising concerns about their presence in all organs. Recent research conducted during heart surgeries shows evidence of microplastic contamination in heart tissues, indicating their unexpected introduction into the cardiovascular system.

These tiny plastic fragments, less than five millimeters wide, have also been found in various places including food, water, air, and other parts of the human body.

Scientists with the American Chemical Society (ACS) conducted a pilot study involving heart surgery patients, where they collected heart tissue samples and blood specimens before and after surgery. Utilizing advanced imaging techniques, they identified microplastic particles ranging from 20 to 500 micrometers wide in most tissue samples. The particles were composed of different types of plastics, including polyethylene terephthalate and polyvinyl chloride. Astonishingly, the blood samples also contained plastic particles, which decreased in size after surgery and represented a wider variety of plastic types.
