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.

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

and of 10 ppb in ozone were associated with increases in all-cause mortality of 7.3% (95% confidence interval [CI], 7.1 of less than 12 μg per cubic meter and ozone of less than 50 ppb, the same increases in PM 2.5 and ozone were associated with increases in the risk of death of 13.6% (95% CI, 13.1 and 1.1% (95% CI, 1.0

The vehicle test matrix had provisions for five vehicles on each emissions standards category (i.e., The test fleet showed statistically significant effects for some pollutants, but not for others. The weighted NMHC emissions showed a marginally statistically significant reduction of 9% for E15 compared E10.

The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Recent research suggests that adverse human health effects occur below current US standards for both PM 2.5 Click to enlarge.

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR).

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. The researchers analyzed extensive satellite and ground-based measurements of nitrogen oxides and carbon monoxide.
