University of Kentucky chemist receives NSF grant to study atmospheric reactions of pollution

Green Car Congress

University of Kentucky Chemistry Professor Marcelo Guzman has received a three-year grant from the National Science Foundation (NSF) for research, education and outreach efforts in the field of environmental and atmospheric chemistry. Both types of emissions cause tiny particles to be suspended in air. —Prof.

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.

San José International deploys 10 Proterra electric buses in airport fleet

Green Car Congress

Funded in part by a $5-million zero-emissions grant from the Federal Aviation Administration, the electric buses replace the aging compressed natural gas bus fleet that has been operating at SJC since 2008. The electric bus fleet is anticipated to reduce ozone emissions by 1.1

EPA awards $6M in research funding to improve air quality models

Green Car Congress

The US Environmental Protection Agency (EPA) announced $5,959,842 million in research funding to nine institutions to improve air quality models used to simulate ozone, particulate matter (PM), regional haze, air toxics, and emerging pollutants. It will also inform the development of strategies for improving air quality.

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

Researchers from Northwestern University and Princeton University have explored the impact on US air quality from an aggressive conversion of internal combustion vehicles to battery-powered electric vehicles (EVs). Across scenarios, we found the more cars that transitioned to electric power, the better for summertime ozone levels.

Portable sensors enable monitoring of pollution on smart phones; inferring pollution maps with greater granularity

Green Car Congress

Computer scientists at the University of California, San Diego have built a portable pollution sensors that transmit transmit their air quality readings to smart phones, allowing users to monitor air quality in real time. million grant from the National Science Foundation. Boxes represent pollution reading locations during that window.
