For the first time, scientists have found microplastic particles in human blood that can be transported throughout the body

Scientists have detected microplastic contamination in human blood for the first time, the Guardian reported Thursday.The tiny particles were found in nearly 80 percent of the subjects’ samples.The finding suggests the particles can travel around the body and may stay in organs, the report said.While the health effects are unclear, researchers are concerned that microplastics can cause damage to human cells in the lab, while air pollution particles have been shown to enter the body and cause millions of premature deaths each year.The Guardian notes that microplastics have now polluted the entire planet, with huge amounts of plastic waste being dumped into the environment, from the summit of Mount Everest to the deepest oceans.Scientists already know that the human body ingests these tiny particles through food and water, and that they also show up in the faeces of babies and adults.The scientists analyzed blood samples from 22 anonymous donors, all healthy adults, and found plastic particles in 17 of them, the report said.In addition, half of the samples also contained PET plastic, which is commonly used in beverage bottles, while a third contained polystyrene, which is used to package food and other products.A quarter of the blood samples contained polyethylene, from which plastic carrier bags are made.One of the study’s authors, Professor Dick Vethaak, an ecotoxicologist at Vrije University Amsterdam in the Netherlands, said: “Our study shows for the first time that polymer particles are present in human blood — a breakthrough result.But we have to expand the study, increase the sample size, evaluate the number of polymers, and so on.”He says many groups are already working on further studies.”There are certainly legitimate concerns,” Vitak told the Guardian.The particles are there and transported throughout the body.”Previous studies have shown that babies have 10 times more microplastics in their faeces than adults, and that babies fed plastic bottles ingest millions of microplastics every day, he said.In the new study, published in the journal Environment International, researchers adapted existing detection techniques to find and analyze particles as small as 0.0007mm.Whittak acknowledged that the amount and type of microplastics varied widely between blood samples, but called this pioneering research and said more work was now needed.A recent study found that microplastic particles can attach to the outer membrane of red blood cells, potentially limiting their ability to deliver oxygen, the Guardian noted.The particles have also been found in the placenta of pregnant women, and in pregnant mice, they quickly travel through the lungs to the fetus’s heart, brain and other organs.Data figure and a review of papers published on Tuesday, weta, cooperate with others to assess the risk of cancer and draw the conclusion: “we urgently need a more detailed study of micro/nano plastic how to affect the structure and process of the human body, and whether or not they can and how the cells and induce cancer, especially in the case of plastic yield increase exponentially.The problem is getting more urgent every day.”(Edit: WDQ)
