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.
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.
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.
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
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.
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.
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.
Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.
In a cohort study of a subset of 2050 newborns from the Children’s Health Study in southern California, researchers at the University of Southern California (USC) found that an increase of 2 standard deviations in prenatal exposure to particulate matter in air pollution was associated with higher newborn total thyroxine (TT4) measures.
Geiger and Alberto Salvo, an associate professor of economics at the National University of Singapore, led the study—their second with São Paulo big data. Officials, Geiger said, will need to weigh the increase in ozone against the decrease in nanoparticles when ethanol is used. are not regulated.
TPS technology has other applications as well, such as emissions reduction from diesel engines and commercial kitchen exhaust systems, plasma treatment of surfaces for cleaning, as well as ozone generation. Results obtained from work performed under a recent DOE grant showed nearly 80% reduction in particulates from a 1.8
WIE offers three grants. The Edith Hannigan McHale Scholarship may be awarded annually to a female student at John Adams High School in Ozone Park, N.Y. The 2U Scholarship program is available only to students at George Washington University , American University , Syracuse University , Washington University in St.
Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. Other participating members of the study included the University of Copenhagen in Denmark and the University of Otago in New Zealand. Dr Kleindienst.
million is coming to 26 government agencies, universities, and electric utilities in Louisiana. The Department of Environmental Quality is awarding 79 grants for the charging stations, using money from the state’s $19.8 Nitrogen oxides and sulfur dioxides are precursor chemicals that, combined with sunlight, create ground-level ozone.
The draft amends the Energy Independence and Security Act of 2007 to include nonprofit hospitals and public health facilities among public institutions eligible for grants and loans for energy efficiency. The draft adds HFCs to the list of similar substances that EPA currently regulates because they deplete the ozone layer.
University of California, Davis researchers will receive $2.8 million in new grants to study the use and impacts of escaped nitrogen from agricultural production. The new Agricultural Sustainability Institute grants and objectives include: $1.5
Jacobson at Stanford University. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b]. These three gases are all greenhouse gases, and ozone is a surface air pollutant. Results of the study suggest that soot is second only to carbon dioxide in contributing to global warming.
80.27, “high ozone season” means the period from June 1 to September 15 of any calendar year and “regulatory control period” means the period from May 1 to September 15 of any calendar year. US Environmental Protection Agency Grants Testing Waiver. In February, 2009, the US EPA granted Renergie, Inc. 40 CFR § 80.27
