SIS in the past fifty years can be reflected in increasing pollution in human brains, according to a new study.
She found an escalating trend in delicate plastic and nianno in the brain tissue of dozens of deaths that were carried out between 1997 and 2024. Researchers also found small particles in liver and kidney samples.
The human body is widely contaminated by Microplastics. It was also found in bloodand semenand Breast milkand Placenta and Bone marrow. The influence on human health is largely unknown, but they were Concerned with strokes and heart attacks.
Scientists also found that the exact plastic concentration was six times higher in the brain samples of people with dementia. However, the damage caused by the dementia in the brain is expected to increase the concentrations, as the researchers said, which means that there should be no causal link.
The researchers, led by Professor Matthew Campin at New Mexico University in the United States, said.
Methodic plastic is divided from plastic waste and pollution of the entire planet, from The summit of Mount Everest to Deepest oceans. People consume small particles Through foodand water and Breathe.
A study published on Thursday found a significant plastic pollution Top in the placenta from early births. Another hadith analysis found that Microleums can prevent blood vessels In the brains of mice, causing nervous damage, but note that human blood capillaries are much larger.
New search, It was published in Nature MedicineSamples of brain, liver and kidney tissue were analyzed from 28 people who died in 2016 and 24 who died in 2024 in New Mexico. Plastic concentration was much higher in brain tissue. He was also higher in brain and liver samples than 2024, compared to those that express 2016.
Scientists extended the analysis with brain tissue samples from people who died between 1997 and 2013 on the American East Coast. The data showed an increasing direction in microscopic brain pollution from 1997 to 2024.
The most common plastic was polyethylene, which is used in plastic bags, food packaging and drink. It constitutes 75 % of the total plastic on average. The particles in the brain were mostly fragments and plastic chips. Plastic concentrations in the members of the age of a person were not affected at death, the cause of death, their gender or their race.
Scientists have noted that only one sample was analyzed from each member, which means that contrast within the organs is still unknown, and that some contrast in the brain samples can be due to geographical differences between New Mexico and the eastern American coast.
These results highlight a The researchers said: “The critical need for a better understanding of methods of exposure, absorption and clearance paths and the possible health consequences of plastic in human tissues, especially in the brain.”
Professor Tamara Galwai of the University of Exeter, UK, who was not part of the study team, said that the increase of 50 % in fine plastic levels over the past eight years reflects the increase in production and the use of plastic materials and was large. “It indicates that if we want to reduce environmental pollution with accurate plastic, the levels of human exposure will also decrease, providing a strong incentive to focus on innovations that reduce exposure,” Galway said.
Professor Oliver Jones, at RMIT University in Australia, said the new research was interesting, but the low number of samples and the difficulty of analyzing small plastic particles without pollution means being careful when explaining the results.
