Air pollution and brain damage: what the science says
Epidemiological studies have linked dirty air to dementia and other brain disorders. Now researchers are trying to determine how pollutants do their damage, and how much harm they cause. Research around the world has linked polluted air to increased risks of dementia, depression, anxiety and psychosis. Credit: Damir Sagolj/Reuters In 2012, Deborah Cory-Slechta at the...

Systemic inflammation may play a role in how air pollution contributes to cognitive impairment
by Raphaël Cayrol, University of Luxembourg Hypothesized pathogenic pathways taken by fine particulate matter (PM2.5) to cause cognitive impairment. PM2.5, particulate matter with a diameter of 2.5 µm and smaller. Two main hypotheses exist regarding the underlying mechanisms of how inflammatory processes are involved in the pathogenic effects of PM2.5 on the development of neurodegenerative diseases: The...

Increase in Air Pollution Could Be Behind Rising Antibiotic Resistance, Finds Lancet Study
By IANS, TWC India Representational Image(Yogesh Kumar/BCCL Delhi) Curbing levels of harmful air pollution could help reduce antibiotic resistance, and related deaths, according to the first in-depth global analysis of the possible links between the two, published in The Lancet Planetary Health journal. The findings indicate antibiotic resistance increases with particulate matter (PM2.5) — made...

New Clues to How Air Pollution Fuels Lung Cancer in Nonsmokers
Megan Brooks April 14, 2023 Air pollution may promote the growth of lung cancer in people who have never smoked by activating normally inactive cells in the lung that harbor cancer-causing mutations, new research indicates. “This work adds to our understanding of the mechanism by which air pollutants promote the earliest stages of lung cancer, particularly in...

Decades of air pollution undermine the immune system, lymph nodes study finds
by Columbia University Lung lymph nodes from six non-smokers between the ages of 20 and 62. Particles of air pollution darken the lymph nodes and impair immune cells within the nodes.

Long-term exposure to air pollution puts teenagers at risk of heart disease
by King’s College London Credit: Pixabay/CC0 Public Domain Long-term exposure to air pollution can increase the risk of high blood pressure in teenagers, a new study has found. The review, published recently in Current Problems in Cardiology, by researchers from King’s College London, looked at eight studies with 15,000 adolescents—children aged twelve and over. Five of...

AIR POLLUTION MAY CAUSE FAR MORE DEATHS THAN PREVIOUSLY THOUGHT
The annual global death toll from long-term exposure to fine particulate outdoor air pollution may be significantly higher than previously thought, according to a new study. That’s because mortality risk was increased even at very low levels of fine particulate outdoor air pollution, ones which had not previously been recognized as being potentially deadly. These...
