Micro -plastics were also found in the brain – even more than other organs

Microemuov He also ends up in the human brain. In a recent US study, plastic was even more in the brain than in other studied organs.

The samples taken from the brain’s frontal logo had accumulated 7-30 times as much as the liver and kidneys.

Most of the plastic found in the brain was polyethylene, for example plastic bags, food packaging and detergent bottles.

Man Get plastic in food, drinking water and breathing air. It comes from cosmetics, synthetic fibers and dust from car tires.

Micro -plastics are constantly spreading throughout the environment as different plastics decompose due to sunlight, water and rubbing.

So far, plastic grooves have been found in many people in many organs. It has even been observed in semen, breast milk and placenta.

The brain is protected by a blood-brain barrier from foreign substances. Published last year laboratory tests They suggested that the blood-brainstorm did not necessarily stop nano-sized plastic particles.

Now In a published study, researchers measured the amount of plastic in the brain, liver and kidneys by several methods. There were 91 samples of the deceased, most of which had died in 2016 or 2024.

The results were first reported last August, and on Monday, a research report appeared in peer -to -peer Nature Medicine -in leaf.

The amount of plastic did not depend on the age, gender or ethnic background of the deceased.

Instead, the plastic accumulation of the organs depended on the year of death. In the deceased last year, 50 % more plastic was more than eight years earlier in the dead.

As a result, the exponential increase in micro -plastics in the environment can also increase the amount of plastic in the body, and researchers write in their report.

In the elderly However, in the deceased, the plastic accumulation was not higher than the others. According to researchers, this may mean that the body is able to clean some of the plastic.

In the brain of demented deceased, there was more plastic than others. In particular, it had accumulated in the walls of cerebral blood vessels and immune cells. However, it is not possible to determine the observation what is the reason and the consequence.

With dementia, the blood-brain barrier and brain purification system work less than others, so the accumulation of plastic may be due to changes caused by the disease and not vice versa, the researchers point out.

How Harmful micro -plastics is for humans and what the amount is dangerous is so far unclear.

Last year Italian scientists detected In a groove study, people whose neck arteries had accumulated a plaque containing micro -plastics were more likely to have a myocardial infarction or stroke than those whose arterial lacquer was not found in plastic.

They also had a higher level of inflammatory markers.

In the arterial cap, the arterial cap had about the same amount of plastic as the brain samples of the study now published.
