As levels of ozone and fine particulate pollution (PM 2.5 ) rise, more patients end up in the ER with breathing problems, according to the largest US study of air pollution and respiratory emergency room visits of patients of all ages. In “Age-specific Associations of Ozone and PM 2.5 among children, 5.1%
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. Emerging contaminants, such as wastewater polluted with medications and personal care products.
A new study now finds that asphalt is a significant source of air pollutants in urban areas, especially on hot and sunny days. Yale researchers found that common road and roofing asphalts produced complex mixtures of organic compounds, including hazardous pollutants, in a range of typical temperature and solar conditions.
Boxes represent pollution reading locations during that window. 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. Nikzad et al. Click to enlarge. Click to enlarge.
The results, published in an open-access paper in the journal Science , suggest that the focus of efforts to mitigate ozone formation and toxic chemical burdens need to be adjusted, the authors suggested. Even so, lotions, paints and other products contribute about as much to air pollution as does the transportation sector.
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.
Deterioration of the ozone layer [kg CFC-11-eq.]. Noise emissions [Person-Pascal/second]. 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 fossil energy resources [kg oil-eq.]. Depletion of fresh water reserves [m 3 ].
In “Estimated Excess Morbidity and Mortality Caused by Air Pollution above ATS Recommended Standards, 2011-2013,” published online in the August edition of Annals of the American Thoracic Society , researchers report on the annual health benefits of meeting more protective standards recommended by the ATS for O 3 and PM 2.5.
The data shows a slight increase in overall emissions from the previous year, and a slight decline in emissions from transportation, which is the state’s main source of both GHGs and air pollutants. tons per person to 10.7 tons per person in 2018, a 24% decrease.

ambient air quality standards (NAAQS) for criteria pollutants. To date, the EPA has established NAAQS for six pollutants: particulate. matter, sulfur dioxide, ozone, nitrogen dioxide, carbon monoxide, and lead. is detrimental to the health, safety, or welfare of any person, or causes damage to property or business.
Google Street View cars can be equipped with Aclima’s mobile sensing platform to measure nitrogen dioxide; nitric oxide; ozone; carbon monoxide; carbon dioxide; methane; black carbon; particulate matter; and Volatile Organic Compounds (VOCs). Aclima, Inc., —Dan Costa, Sc.D.,
As well as copper, the excavated ore layers often also contain arsenic—a highly toxic, inorganic pollutant that poses a threat not only to human health but to the entire ecosystem. Other project partners are also evaluating UV- and ozone-assisted as well as microbial oxidation processes. Raw copper smelting in a blast furnace.
For wide-spread adoption, the analysis assumes that the electric vehicle market share grows from approximately 1% today to a substantial share of total sales, such that by 2050 electricity is powering 53% of personal vehicle miles traveled. levels throughout the United States.
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
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. Compare personalized solar quotes online and receive guidance from unbiased Energy Advisers. Get started here. –
EVs don’t emit any harmful pollutants to the environment like soot, hydrocarbons, lead, ozone, carbon monoxide, or volatile organic compounds. Drivers have to download apps, fill in their personal details (including credit card information), wait for the app to communicate with the charger, and then begin charging.
Global warming plays a role in thinning the ozone layer, thus permitting harmful rays’ penetration to the earth. Lastly, by improving this infrastructure, the economy will grow by a significant margin and cut down on the greenhouse gas emission polluting the air. The rays can cause skin damage to humans and other species.
And personally I like better simple solutions. I mean, when the electricity it uses is produces, pollution still happens, just not "right from your car"? Neutral jakem @ Apr 19th 2009 5:21PM Thats only a better solution for people who have a garage at home. like people driving futuristic electric cars and everything being clean!
and of 10 ppb in ozone were associated with increases in all-cause mortality of 7.3% (95% confidence interval [CI], 7.1 When the analysis was restricted to person-years with exposure to PM 2.5 of less than 12 μg per cubic meter and ozone of less than 50 ppb, the same increases in PM 2.5 and 1.1% (95% CI, 1.0
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
The station, which is proposed to be fed from an existing hydrogen pipeline, will fuel port trucks and be publicly available for personal vehicles. Additional benefits of this location include the presence of an existing hydrogen pipeline that is owned by Air Products, making the fuel 100% locally sourced.
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. Reducing emissions from diesel engines remains one of the most important air quality challenges facing the country, according to the EPA.
Of course, it's not enough to detect air pollutants; you must also remove them. Ionization can itself create ozone. The state of California has banned such ozone generators entirely. LG led its presentation with personal air purifiers instead of televisions. In fact, ionization can itself create ozone.
Piloting the bullet-shaped Bell X-1 rocket plane in 1947, Chuck Yeager became the first person to exceed the speed of sound while in horizontal flight. The main obstacles will be regulatory and, especially, environmental: Supersonic airliners could be hugely more polluting than their subsonic counterparts. Everett Collection/Alamy.
Air pollution remains a major threat to the health of many Americans, but stricter emissions rules could help, according to the American Lung Association. population—live in areas with unhealthy areas of air pollution. And spikes in deadly air pollution are the most severe recorded in the history of the report.
