Elevated levels of air pollutants are associated with bone damage among postmenopausal women, according to new research led by scientists at Columbia University Mailman School of Public Health. The effects were most evident on the lumbar spine, with nitrous oxides twice as damaging to the area as in normal aging.

The research findings appear in the journal eClinicalMedicine.

Previous studies on individual pollutants have suggested adverse effects on bone mineral density, osteoporosis risk, and fractures in older individuals...

First-in-the-world study suggests that even brief exposure to air pollution has rapid impacts on the brain. A new study by researchers at the University of British Columbia and the University of Victoria has shown that common levels of traffic pollution can impair human brain function in only a matter of hours.

The peer-reviewed findings, published in the journal Environmental Health, show that just two hours of exposure to diesel exhaust causes a decrease in the brain’s functional connectivity – a measure of how The study provides the first evidence in humans, from a controlled experiment, of altered brain network connectivity induced by air pollution.

Scientists have identified a mechanism that explains how fine air pollution particles might cause lung cancer, according to a study published today in eLife.

The findings could lead to new approaches for preventing or treating the initial lung changes that lead to the disease.

Tiny, inhalable fine particulate matter (FPM) found in air pollutants has been recognised as a Group 1 carcinogen and a substantial threat to global health...

There is good evidence that polluted air increases the risk of respiratory problems such as asthma – as well as organ inflammation, worsening of diabetes and other life-threatening conditions. But new research suggests air pollution can also fuel something else: chronic kidney disease, or CKD, which occurs when a person’s kidneys become damaged or cannot filter blood properly.

Recently published in PLOS ONE, a University of Michigan study highlights the lesser-known connection...
