Toxic particles in the air can travel from the lungs to the brain and cause neurological damage



A recent study in the UK in collaboration with a Chinese scientific institution found that contaminated air particles could travel from the lungs to the brain through the bloodstream and stay there, causing a variety of neurological conditions. It became clear that there was.

According to a study conducted by University of Birmingham, UK He found it Breathing polluted air can cause toxic particles to travel from the lungs to the brain through the bloodstream, contributing to brain damage and neurological damage. ..

In fact, according to the findings, these toxic particles should have found a direct route through these two organs. Stay in the brain forever Will cause a series of different illnesses.

Scientists have discovered the potential Direct route used by various particles of polluted air Through Blood circulation With its signs Once there, they stay in the brain longer than other major metabolic organs ..

Survey results, University of Birmingham Various scientific institutions in (UK) and China were published in the journal this Monday. Minutes of the National Academy of Sciences (PNAS, according to the English acronym).

Researchers revealed what they had Discovered various fine particles in human cerebrospinal fluid collected from patients suffering from brain disorders Explains a statement from the aforementioned academic campus that ultimately unveiled a process that could result in toxic substances in the form of particles in the brain.

Iseult Lynch at the University of Birmingham Point out that there is Knowledge gap about the harmful effects of particulates on the central nervous system .. “This work sheds new light on the relationship between particle inhalation and subsequent movement within the body,” he states.

The data suggests that By passing through the bloodstream from the lungs rather than through the nose directly, up to eight times as many particles can reach the brain. ..

According to the author, these results are Air pollution and the harmful effects of such particles on the brain ..

PM: Particulate polluted air

The Air pollution Is a cocktail of many toxic ingredients, and the term PM (an English acronym for particulate matter) is A mixture of small solid and liquid particles found in the air ..

These particles It is categorized according to size Especially fine things, PM2.5 and PM0.1 are the most worrisome about adverse health effects. ..

Specifically, ultrafine particles You can escape from the body protection system Includes sentinel immune cells and biological barriers.

Recently it has been shown to be Strong relationship between high levels of air pollution And mark Neuroinflammation Similar changes to those that occur in Alzheimer’s disease When Cognitive impairment even in the elderly and children I remember college.

A team of scientists have discovered that inhaled particles can enter the bloodstream and eventually reach the brain, damaging the blood-brain barrier and surrounding tissues.

one time brain ,particle They are difficult to remove and are retained longer than other organs ..

Although these results are provided New evidence of risk of particle contamination of the central nervous system Scientists recommend further investigating the mechanism of how inhaled environmental particles reach the brain.
