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.
and of 10 ppb in ozone were associated with increases in all-cause mortality of 7.3% (95% confidence interval [CI], 7.1 of less than 12 μg per cubic meter and ozone of less than 50 ppb, the same increases in PM 2.5 and ozone were associated with increases in the risk of death of 13.6% (95% CI, 13.1 and 1.1% (95% CI, 1.0
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. —Prof. —Prof.
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.
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. has fully characterized a key chemical reaction that affects the formation of pollutants in smoggy air in urban areas.

This new program, partially funded with the DOE grant, will allow pre-production testing at AAR’s Transportation Technology Center, Inc. g/bhp-hr of NOx, a reduction of 400 times.
million in additional California Air Resources Board (CARB) funding to replace heavy-duty trucks through the Valley Air District’s grant program. The District is currently working on reaching attainment for the federal 8-hour ozone and PM 2.5 The San Joaquin Valley Air District Governing Board unanimously voted to accept $12.9
The project selections were approved as part of the Low- or No-Emission (Low-No) Grant program, which funds the deployment of zero-emission and low-emission transit buses and supporting equipment and facilities. By retrofitting the garage to service electric buses, the agency will also lower pollution in the surrounding community.
This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., —Schnell et al.
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.
million in new grants to study the use and impacts of escaped nitrogen from agricultural production. Data on agricultural nitrogen pollution are limited, and some nitrogen pollution forms are difficult to monitor. The new Agricultural Sustainability Institute grants and objectives include: $1.5 Tom Tomich.
Jacobson used a computer model of global climate, air pollution and weather that he developed over the last 20 years and updated to include additional atmospheric processes to analyze how soot can heat clouds, snow and ice. 1990; Anisimov, 2007] and chemical production of ozone in already-polluted locations [Jacobson, 2008b].
The US Department of Energy (DOE) National Energy Technology Laboratory (NETL) awarded a grant to H-GAC with an objective of accelerating the introduction and penetration of electric transportation technologies into the cargo transport sector. The project will have additional impact with an expected reduction in GHG emissions by 37.5
The California Air Resources Board (ARB) issued a grant solicitation for demonstration projects on zero-emission off-road equipment. Off-road equipment is a significant source of diesel PM, as well as NO x emissions that lead to ozone and secondary PM, ARB noted.
For its part, EPA is withdrawing the Clean Air Act preemption waiver it granted to the State of California in January 2013 as it relates to California’s GHG and ZEV programs. criteria pollutants—is not affected by the action.
million in grants to deploy 70 VNR Electric trucks in Southern California for regional freight distribution and drayage. The US Environmental Protection Agency’s (EPA) Targeted Air Shed Grant Program is providing $20 million in funding, supplemented by $1.7 Volvo Trucks North America was awarded $21.7
The Clean Air Act (CAA) requires the use of low-volatility gasoline during the summer months in order to limit the formation of ozonepollution. As required by law, EPA and DOE evaluated the situation and determined that granting the waiver was in the public interest.
Funding will be in the form of cooperative agreements or grants. million tons of NO x , which contribute to the formation of ozone and additional fine particles. A single proposal may target multiple fleets, fleet types and/or diesel emission reduction solutions.
SOAS objectives include the direct quantification of VOC, ozone and NO x surface fluxes and the reconciliation of differences with “blank-down” emission estimates. It seeks a better understanding of HO x /NO x /ozone/organics/aerosol distributions, sources and sinks. million in grants to 13 institutions as part of SAS.
In the first, they found that when fuel prices drove residents of São Paulo, Brazil, to mostly switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. Officials, Geiger said, will need to weigh the increase in ozone against the decrease in nanoparticles when ethanol is used.
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.
The draft requires states to establish goals for reducing global warming pollution from the transportation sector and requires large metropolitan planning organizations to submit transportation plans to meet those goals. Title III, Reducing Global Warming Pollution , (the cap-and-trade title), has eight subsections.
The state has also said that it’s aiming to get one million zero-emission vehicles on its roads by 2030, along with its plan to eliminate greenhouse gas pollution entirely by 2050. This standard will make clean vehicles more accessible across the state and improve air quality in local communities overburdened by pollution from busy roadways.”
In addition, achieving the renewable fuel standard would increase the federal budget outlays, mostly as a result of increased spending on grants, loans, loan guarantees, and other payments to support the development of cellulosic biofuels and foregone revenue as a result of biofuel tax credits. Barriers and opportunities.
Isoprene, a five-carbon diene formed naturally in plants and animals and a precursor of ozone, contributes more than 40% of these emissions. The scientists pointed out that converting the epoxides to aerosol is likely to be higher in polluted environments, because the aerosols’ acidity is generally higher when human activity is present.
The Department of Environmental Quality is awarding 79 grants for the charging stations, using money from the state’s $19.8 Volkswagen sold about 590,000 vehicles equipped with devices that defeated their pollution control features, leading to increased emissions of oxide. Another $7.3
On their 100+ mile round trip, these trucks burn diesel fuel that damages the ozone, spews out noxious particulates that seek-out lungs and eyes along with oxides of nitrogen that help create smog, along with other nasty—and toxic—unpleasantness. tons of pollutant emission reductions and displacing more than 2.75
NIEHS goes on to say that air pollution is also linked to cancers, cardiovascular disease, respiratory disease, and other disorders. The CSB has two methods of funding: Rebates and Grants. Currently, the EPA is accepting applications to the 2023 CSB Rebate Program until Jan. 31st, 2024 at 4pm ET.
EVs don’t emit any harmful pollutants to the environment like soot, hydrocarbons, lead, ozone, carbon monoxide, or volatile organic compounds. In the UK, the deal is sweeter because you get a £3,000 grant. Why purchase an EV. Besides fuel cost savings, you might want to purchase an EV because of its low carbon footprint.
Every time it rains, fish living downstream of storm drains are exposed to pollutants, including the tire-derived compound 6PPD-quinone, in the runoff. 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.
CALSTART will focus on strategies to help develop the market and commercialize the trucks deployed and tested under this grant. This marks the single largest grant ever made to advance zero emission trucks serving ports in the United States. The total investment in the project was $40 million.
