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...

Study of US seniors Strengthens link between Air Pollution and Premature Death

A new study of 60 million Americans – about 97% of people age 65 and older in the US – shows that long-term exposure to airborne fine particulate matter (PM2.5) and ozone increases the risk of premature death, even when that exposure is at levels below the National Ambient Air Quality Standards (NAAQS) currently established by the U.S. Environmental Protection Agency.

Twenty-four h post-exposure change of heart rate variability (HRV) associated with PM2.5, and the intervention effect of B vitamin supplementation.

B vitamins can mitigate the impact of fine particle pollution on cardiovascular disease, according to new research at Columbia University’s Mailman School of Public Health. Healthy non-smokers who took vitamin B supplements nearly reversed any negative effects on their cardiovascular and immune systems, weakening the effects of air pollution on heart rate by 150%, total white blood count by 139%, and lymphocyte count by 106%.

The study initiates a course of research for developing preventive pharmacological interventions using B vitamins to contain the health effects of air pollution...

Hypertension was associated with exposure to some air pollutants commonly associated with the burning/combustion of fossil fuels, dust and dirt, a new study shows. Researchers suggest people – especially those with high blood pressure – limit their time outdoors when pollution levels are high. “In our analysis of 17 previously-published studies we discovered a significant risk of developing high blood pressure due to exposure to air pollution,” said Tao Liu, Ph.D. “People should limit their exposure on days with higher air pollution levels, especially for those with high blood pressure, even very short-term exposure can aggravate their conditions.”

They performed a meta-analysis of available published studies in the world assessing health effects of all air pollution on HT risk...
