China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The findings associated ozone exposure with markers of platelet activation and increased blood pressure.

Researchers fully characterize reaction that affects ground-level ozone formation; a small but significant impact on predictive models

Green Car Congress

The two combine in the atmosphere to make either nitric acid or peroxynitrous acid; the so-called branching ratio of these two chemicals is important in models of ozone production. This means less of the hydroxyl radical and nitrogen dioxide go away, leading to proportionately more ozone, mostly in polluted areas, Okumura said.

Cal Energy Commission approves $1M grant to develop 12L near-zero NOx nat gas engine

Green Car Congress

The California Energy Commission approved a $1-million grant to develop a 12-liter natural gas engine that produces near-zero nitrogen oxide (NO x ) tailpipe emissions. Even higher potential may exist, depending in large part on the removal of current obstacles through Research Development and Demonstration and deployment.
