Fine particles could be dangerous to health and we breathe them daily even at home, here’s how

According to a recent study, pollution could cause serious illnesses due to the presence of fine dust.

In a previous article “From fireplaces to pellets, pollution increases and heart, respiratory and stroke diseases grow” we talked about the danger of particulates present in the air.

These by their nature have the ability to enter the body through breathing. Therefore, not only the lungs and the heart are at risk, but also the brain for researchers. Furthermore, we suggest reading another article: “Lung cancer and screening also in those who have had Covid? What few people know “.

Pollution: Fine particles could be dangerous to health, a study says

A group of researchers from the University of Birmingham and some Chinese research institutes have published research on PNAS (vol.119 (26), June 2022; https://doi.org/10.1073/pnas.2117083119).

He would have highlighted that by breathing polluted air they also inhale fine powders. Some of these could be potentially toxic. In fact, according to the study, the polluted air would be rich in particulates, such as PM 2.5 and PM 0.1.

I uploaded (PM) they are particularly dangerous. In fact, being very fine they are not recognized as a threat by the sentinel immune cells (dendritic cells). Hence, penetrating the organism through the breathingarrive at the lungs. From here, through the blood circulation could reach the brain. At this point the damage can be potentially serious: cognitive and neurological.

I study

By examining some patients with brain disorders, scientists would have found fine dust in cerebrospinal streams. As a result, they would find that this can go all the way to the brain.

Professor Iseul Lynch of the University of Birmingham and co-author of the research commenting on the results would have said that “this work sheds new light on the link between the inhalation of particles and how they subsequently move around the body”. Despite some gaps in the knowledge of particulates on health.

Furthermore, the research revealed a very strong link between air pollution (at high levels) and cognitive changes similar to Alzheimer’s. Not only in older people, but also in children.

Among other things, once the fine particles enter the brain they are difficult to eliminate and remain longer than in other organs.

However, before confirming their research, the researchers recommend further investigations into the relationship between fine particles and brain damage.
