A University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. Water from mining of oil sands and oil shale. Heavy metals in soil.
The first peer-reviewed study to directly quantify how emissions from oil and natural gas (O&NG) activities influence summertime tropospheric ozone (O 3 ) pollution in the Colorado Front Range confirms that chemical vapors from oil and gas activities are a significant contributor to the region’s chronic ozone problem.
Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.
The US Environmental Protection Agency (EPA) proposed standards to reduce harmful air pollution from oil and gas drilling operations. The VOC reductions in the proposal are expected to help reduce ozone nonattainment problems in many areas where oil and gas production occurs.
Photochemical Ozone Creation Potential (kg Ethene equivalent). Quantifies the production of pollutantozone (? to ozone layer), the results of the reaction of sunlight on NO x and volatile organic compounds. water, and non-renewable energies (crude oil, coal.) Quantifies the quantity of energy (crude oil, coal.)
These findings will help to improve the understanding of global processes involved in cloud formation and air pollution and to refine the corresponding models. This is one of the volatile organic compounds in the oils of conifer trees, and it also occurs in eucalyptus and rosemary. Photo: Paul Scherrer Institute/Mahir Dzambegovic).
Data collected during a major 2010 state-federal atmospheric research project show that the first-in-the-nation regulation requiring ocean-going vessels to use clean fuel when near the California coast has been extremely effective in reducing sulfur dioxide pollution from ships, according to the California Air Resources Board (ARB).
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) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposed updates also add emissions reduction requirements for sources of methane and VOC pollution that were not covered in the 2012 rules.
Depletion of fossil energy resources [kg oil-eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fresh water reserves [m 3 ]. Depletion of metal resources [kg iron-eq.].
CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. emissions by more than 20%.
Pechman for the Western District of Washington has ruled that the Washington Department of Ecology, Northwest Clean Air Agency, and Puget Sound Clean Air Agency must regulate greenhouse gas emissions (GHGs) from the five oil refineries operating in Washington State. ambient air quality standards (NAAQS) for criteria pollutants.
The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2.
That study provided estimates of vessel traffic (numbers of vessels and transits) based on modeling of current vessel activity patterns, growth potential, and vessel projection scenarios, including diversion from other routes, and oil and gas development.

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). The researchers included a sixth pollutant, ammonia (NH 3 ).
eutrophication; ET = ecological toxicity; FEC = fossil energy consumption; WU = water use; LO = land occupation; “The rest” includes acidification; smog formation; ozone layer depletion; and human health effects. For gasoline, the study reflects the US context in which crude oil is to a large extent imported and refined domestically.
The Bakken Formation, a shale oil and gas field in North Dakota and Montana, is emitting roughly 2% (about 250,000 tons per year) of the globe’s ethane, according to new study led by researchers at the University of Michigan. Between 2005 and 2014, the Bakken’s oil production jumped by a factor of 3,500, and its gas production by 180.
When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
The team, from the Desert Research Institute, University of Colorado Boulder and NOAA, and Stanford University, began by defining a consistent vocabulary, first by jettisoning the popular umbrella label of “fracking” applied to unconventional oil and natural gas development.
The use of petroleum-derived fuels is an important source of reactive gas-phase organic carbon that provides key precursors to the formation of secondary OA (SOA) and tropospheric ozone. We determine the relative importance of gasoline and diesel sources for SOA formation in, and downwind of, urban regions. —Gentner et al.
As part the Israeli Ministry of Environmental Protection’s (MoEP’s) action plan to reduce pollution in Haifa Bay in Israel, Israel Police are actively enforcing exclusion rules that bar heavy vehicles in downtown Haifa Bay at certain times of the day. Air pollution, Haifa. —MoEP Director General Yisrael Dancziger.
Together, the proposals would reduce oil imports by approximately 20 billion barrels. The proposal retains the proven regulatory design of previous EPA standards for light-duty vehicles, but leverages advances in clean car technology to further reduce both climate pollution and smog- and soot-forming emissions.
One key issue that the Waxman-Markey discussion draft does not address is how to allocate the tradable emission allowances that restrict the amount of greenhouse gas emissions from electric utilities, oil companies, and other sources. Title III, Reducing Global Warming Pollution , (the cap-and-trade title), has eight subsections.
Inventorying criteria air pollutants showed that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 Detailed assessments of the end-of-life fate of vehicles, motor oil and infrastructure should also be factored into decisions. Chester and Horvath (2009).
The best cost estimates of cellulosic biofuel are not economical compared with fossil fuels when crude oil’s price is $111 per barrel. However, air-quality modeling suggests that production and use of ethanol to displace gasoline is likely to increase air pollutants such as particulate matter, ozone, and sulfur oxides.
NO x is a precursor for both ground level ozone and secondary PM 2.5 The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment.
The car still has plenty of other impacts – higher carbon emissions and energy use, contribution to sprawl and land use, oil dependency and so on – but for these specific smog-forming pollutants, SOREs have a major impact.
Ozonepollution 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.
EVs don’t emit any harmful pollutants to the environment like soot, hydrocarbons, lead, ozone, carbon monoxide, or volatile organic compounds. That’s because you no longer get to spend money on fuel, oil, engine checkups, and so on. Besides fuel cost savings, you might want to purchase an EV because of its low carbon footprint.
Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and of oil and natural gas. for 2030 and beyond.

The World Health Organization now estimates that in 2012 around 7 million people died—one in eight (12.5%) of total global deaths—as a result of air pollution exposure. million deaths linked to indoor air pollution and 2.6 million deaths related to outdoor air pollution—5.9 million deaths in total.
The Environmental Protection Agency (EPA) announced a new review of the Ozone National Ambient Air Quality Standards (NAAQS). In October 2021, EPA announced a reconsideration of the previous Administration’s decision to retain the NAAQS for ozone. In many of the areas designated as not meeting the current 2015 standards, work remains.
The US Environmental Protection Agency (EPA) issued final updates to its 2012 volatile organic compounds (VOCs) performance standards for storage tanks used in crude oil and natural gas production and transmission. In addition, the rule streamlines compliance and monitoring requirements for tanks that have already installed controls.
Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
1,000 to 21,000) deaths due to changes in ozone concentrations. 900 to 11,000) ozone-related early deaths per year. 300 to 4,000) ozone-related premature mortalities per year. 2000 (90% CI: 0–4,000) early deaths from ozone, according to the study. 53,000 (90% CI: 24,000–95,000) PM 2.5 related premature deaths and ?5,000
Farm machines burning oil, gasoline and diesel release nitrogen to the air. Data on agricultural nitrogen pollution are limited, and some nitrogen pollution forms are difficult to monitor. Wastes from cattle, chickens and other livestock include nitrogen. Tom Tomich.
Air pollution monitoring by the Houston Health Department in 2019 and 2020 recorded levels of formaldehyde, a known carcinogen, along the Houston Ship Channel that pose potential health risks to surrounding neighborhoods. — “Formaldehyde Air Pollution in Houston”. parts per billion.
Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather?
Electrify America chargers In a strange turn of events, the oil giant BP may rescue Tesla Supercharger sites left in the lurch after Tesla’s still-puzzling decision to cut its Supercharger program. EVs are part of the remedy, as progress is also made in curbing pollution from power plants. population lives with unhealthy air.
