UB study finds link between ambient ozone exposure, artery wall thickness

Green Car Congress

MAY 31, 2019

Long-term exposure to ambient ozone appears to accelerate arterial conditions that progress into cardiovascular disease and stroke, according to a new University at Buffalo study. The study found that chronic exposure to ozone was associated with a progression of thickening of the main artery that supplies blood to the head and neck.

A new statistical method developed by researchers at KAUST (King Abdullah University of Science and Technology, Saudi Arabia) can detect abnormal ozone levels within large bodies of monitored data. Ozone is the reactive form of oxygen that contains three atoms per molecule (O 3 ) rather than the normal two.

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.
