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. 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.

Study finds rising temperatures increase risk of unhealthy ozone levels absent sharp cuts in precursors

Green Car Congress

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). Ozone formation. Even short periods of unhealthy ozone levels can cause local death rates to rise. Scenario A2 and RCP 8.5.

Japan, China researchers develop plasma-assisted MnO2 filter that produces zero-NO2, -SO2 diesel exhaust

Green Car Congress

This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. 2018.12.077.

have developed a simulator able to predict tropospheric ozone concentrations across the whole of South and East Asia. The project was carried out in collaboration with Tsinghua University in China, The Energy and Resources Institute (TERI) in India, and the International Institute for Applied Systems Analysis (IIASA) in Austria.

6PPD-quinone derived from tire debris is toxic to two trout species, not just coho salmon

Green Car Congress

6PPD is an antioxidant and antiozonant that helps prevent the degradation and cracking of rubber compounds caused by exposure to oxygen, ozone and temperature fluctuation. For both trout species, the researchers observed an increased blood glucose level after 6PPD-quinone exposure, suggesting it affected the fish’s energy metabolism pathways.

UCI-led study finds California’s strict air quality regulations have helped farmers

Green Car Congress

They found that reductions in ground ozone during this 35-year period resulted in $600 million in increased production annually by the early 2010s. Another difference is that some grains can be annually modified to withstand greater heat and even higher ozone levels in the air. An open-access paper on the work appears in Nature Food.

Argonne researcher using hydrous ethanol as a dual fuel to lighten the carbon footprint of locomotives

Green Car Congress

El-Hannouny’s research is funded by two different DOE offices in the Office of Energy Efficiency and Renewable Energy (EERE). The first is the Vehicle Technologies Office (VTO), which aims to advance combustion engine technology and simultaneously reduce criteria emissions, such as carbon monoxide, nitrogen oxides and ozone.
