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

Green Car Congress

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. Paul, Minnesota; Chicago; and Los Angeles. While the study finds an association between air pollution and atherosclerosis, researchers aren’t clear on why.

Study finds modifying urban form may be a strategy to reduce air pollution

Green Car Congress

Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journal Environmental Science & Technology.

Why Schools Should Electrify Their Bus Fleets

Blink Charging

While it’s obvious that the internal combustion engine vehicles are polluting the air outside the buses, what you may not know is that numerous studies show that the pollution from the burning diesel regularly makes its way into the buses.

Study finds that cities with highly contiguous built-up areas have on average lower NO2 concentrations

Green Car Congress

In the first empirical study using satellite measurements to explore the relationship between urban form and air pollution, a team from the University of Minnesota has found that cities with highly contiguous built-up areas have, on average, lower concentrations of nitrogen dioxide (NO 2 , a key component of urban air pollution).

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).

Researchers report on potential long-range atmospheric emissions impacts of increased ethanol fuel use in North America

Green Car Congress

Acetaldehyde is classified as a hazardous air pollutants (HAP) regulated under Title III of the Clean Air Act Amendments. This is accompanied by a modest regional decrease in surface ozone (of order 1%). Numbers inset give the total North American ethanol source. Labels at left are months (e.g., DJF = December, January, February).
