Debris bacteria age blood vessels

According to RCO News Agency, It is well known that air pollution can have severe effects on heart health. Any particle smaller than 2.5 microns (20 times thinner than a strand of hair) can enter the bloodstream through the lungs and increase the risk of heart attack and stroke.

According to Advanced Science News, A new study has shown how a little-known type of pollution can speed up the aging of cardiovascular tissue. This type of air pollution, which is known as “bioaerosol”, contains microscopic organisms such as bacteria, viruses, fungal spores, and pollen and small particles, and is usually found at the collection point of household waste.

“Caiwen Ou” (Caiwen Ou), researcher of “Southern Medical University” (SMU) in China, said: Municipal waste collection bases are necessary for daily life. Closed environments and large amounts of kitchen waste lead to the growth of microorganisms and pose significant risks to the health of residents. This research shows that there is a high concentration of pathogenic bioaerosols in the environment of household waste collection centers. In addition, it was found that chronic exposure to this high concentration can accelerate vascular aging in mice.

This is the first research to show that microbes in bioaerosols can speed up the aging of blood vessels, exacerbating the known health risks of air pollution.

Kayon O and his colleagues also identified how this happens at the molecular level. This discovery could pave the way for the development of treatments against the long-term effects of this type of pollution. The research group hopes their research will be a wake-up call for governments and regulatory agencies to start implementing stricter policies aimed at protecting people such as workers and those living near waste collection sites who are chronically exposed to bioaerosols.

This research was published in “Advanced Science” magazine.
