Scientists say human organs can absorb microplastics
According to scientists at Arizona State University, microplastics and nanoplastics can get into your body and attach to your organs.
Previous studies on human plastic consumption rates have shown that particles can pass through the gastrointestinal tract. In fact it is possible Humans may have consumed 39,000 to 52,000 microplastic particles According to National Geographic, it’s been a year. Particle evidence not only for beer, salt, seafood, sugar, alcohol, and honey, Fish seeds Like a shellfish.
However, to date, no studies have been conducted on whether they accumulate in our organs. Graduate students Charles Rolsky and Varun Kelkar decided to investigate using samples of brain and body tissue. They started by exposing the tissues of the lungs, liver, fat, spleen, and kidneys to small particles of plastic to find a way to detect the presence of microplastics.
Next, 47 samples were taken from human liver and fat and analyzed using mass spectrometry. They were looking for different types of plastic components within their organization, such as polycarbonate (PC), polyethylene terephthalate (PET), polyethylene (PE).
Evidence of plastic contamination was detected in all samples. In particular, researchers have discovered bisphenol A (BPA). Bisphenol A is still a substance used in many food containers, despite environmental concerns.
“Tissue providers provided detailed information about their lifestyle, diet, and occupational exposure,” says Dr. Rolf Halden, who tested the sample at the lab. Sources and routes of exposure for micro and nano plastics. “
As for the effects on human health, the risks posed are not well understood. So far, wildlife and animal studies have linked exposure to microplastics and nanoplastics to infertility, inflammation, and cancer, but the health consequences for people are unknown.
“We don’t want to be vigilant, but we are concerned that these ubiquitous, non-biodegradable substances can enter and accumulate in human tissues. I don’t know about the possibilities,” Kelker says.
Scientists define microplastics as pieces of plastic that are less than 5 mm in diameter, or about 0.2 inches. Nanoplastics are even smaller, with diameters less than 0.001 mm. “We find that plastics pollute the environment almost everywhere on Earth. Over the decades, seeing plastic as a threat has broken us out of seeing plastic as a great advantage.” Adds Rolsky.
Researchers will conduct epidemiological studies to assess the risk of microplastics to human health. Meanwhile, they share online tools that help them collect results from similar tests being conducted around the world.
“This shared resource helps build a plastic exposure database so that we can compare the exposure of organs and groups of people in time and geographical space,” concludes Halden.
