, the researchers analyzed the heart tissues of 15 people before and after they underwent heart surgery.Using a laser direct infrared chemical imaging system and scanning electron microscopy for their investigation, the team found that microplastics existed in the tissues taken both prior to and post-surgery.
The researchers also collected blood samples from half of the participants, both before and after the surgery. Nine types of microplastics were detected in blood samples, both pre-and postoperative. The maximum diameter of the microplastic was 184 μm. In the blood samples, the type and diameter distribution of microplastics showed a change in size after the surgical procedure, suggesting that microplastics were introduced to the body during surgery as well.However, the researchers noted that microplastics were not universally present in all tissue samples. Nine types of particles were found across five types of tissues with the largest measuring 469 μm in diameter.
It’s estimated that one truck full of plastic garbage is dumped into the ocean every minute and there are approximately 14 million tons of microplastics sitting on the. And these numbers are increasing, even though efforts are being made to reduce global plastic consumption. “Further research is needed to examine the impact of surgery on microplastic introduction and the potential effects of microplastics in internal organs on human health,” noted the researchers in the study.Microplastics have been detected in human stool, lungs, and placentas, which have direct exposure to the external environment through various body cavities, including the oral/anal cavity and uterine/vaginal cavity.

Climate scientists dismiss Australian geologist's 'ridiculous' carbon dioxide claimsScientists have dismissed as 'ridiculous' an Australian geologist's claims that the climate crisis is part of the Earth's geologic history as the planet's atmosphere used to have significantly higher levels of carbon dioxide. Scientific consensus has firmly established carbon emissions from human activity -- particularly the burning of fossil fuels -- have warmed the planet. A climate professor told AFP the misleading claims appear to refer to prehistoric carbon dioxide levels from when the Earth could not support human life.
