American scientists from the University of New Mexico found that germs have accumulated in large amounts in the human brain. The concentration of polymer particles in brain tissues was significantly higher than other organs. The study was published scientifically magazine Nature Medical.
The team examined the 52 -person tissue samples taken from 2016 to 2024. Each test contained germ particles, but the content in the brain was 30 larger than the level of the liver and kidneys. These puzzled experts, because the brain is protected by a hematenseenencephalic barrier from harmful substances.
From 1997 to 2013, a comparison with previous tissue examples has revealed a clear trend: the concentration of germ in the human body increases over time.
Scientists associate this with plastic wastes with the expandation of environmental pollution. From 1950 to 2019, approximately 9 billion tons of plastic was produced, which was divided into micro and nanoparticles and polluted the soil, water and air.
In particular, the connection between microplasty and dementia, which is worrying. In the brain of people diagnosed with dementia, the plastic concentration was higher than those who did not suffer from this disease.
However, researchers cannot say exactly whether the accumulation of plastic development of the dementia is the result of existing disorders such as brain tissue atrophy and hematokencephalic barrier.
Experts called to develop strategies to reduce more comprehensive studies and use of microplasty on the human body. In the meantime, each of us, including the brain, including the daily plastic particles accumulated in the organs we continue to absorb.
Previously, scientists To create Connection between microplasty, cancer and damage in many organs.
