Those highways include Interstates 8, 10, 80, 210 and 710 and state routes 60 and 99 in California; I-84 in Oregon; and I-90 in Washington. An additional 41 sites on other highways that connect to I-5 are being proposed for electrification.

Of these deaths, 57% were associated with pollution caused by energy consumption [e.g., Goodkind et al.
Decarbonizing utilities: Washington passed the first law in the United States that outlines a pathway for a combined gas and electricity utility to transition away from gas for all of its customers. Proposed by Puget Sound Energy, the bill allows the utility to merge electric and gas customers into a single rate.

The study included 430 full-term (?37
When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).
concentrations and particle composition from area samples collected in the subways of Philadelphia, Pennsylvania; Boston, Massachusetts; New York City, New York/New Jersey (NYC/NJ); and Washington, District of Columbia. Washington had the next highest levels at 145 ?g/m The researchers found an elevation in the PM 2.5
Researchers at Washington State University, with colleagues at Kyung Hee University and Boeing Commercial Airplanes, have been developing liquid hydrocarbon/oxygenated hydrocarbon-fueled solid oxide fuel cells (SOFCs) for aviation (the “more electric” airplane) and other transportation applications, such as in cars. Click to enlarge.
Scott Fruin, Neelakshi Hudda and colleagues noted that past research has measured pollution from air traffic before, but most of these studies only sampled air within a couple of miles, at most, from airports. The results also indicate that the air quality impact areas of major airports may have been seriously underestimated.
Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it. the least.
Researchers at the University of California, Davis, have found a link between traffic-related air pollution and an increased risk for changes in brain development relevant to neurodevelopmental disorders. The researchers compared the brains of rat pups exposed to traffic-related air pollution with those exposed to ?ltered ltered air.
Based on their findings in a new study, researchers from the University of Washington and the University of Minnesota suggest that modifying urban form—as a means of affecting motor vehicle usage—may be a strategy to mitigate urban air pollution. Their paper appears in the ACS journal Environmental Science & Technology.
Washington Governor Jay Inslee announced a set of proposals to transition Washington to cleaner sources of energy and to meet greenhouse gas (GHG) emission limits adopted by the state Legislature in 2008. The proposals build on a comprehensive executive order issued by the governor in April. Cap-and-trade. M, capital budget).
Cooking, cleaning and other routine household activities generate significant levels of volatile and particulate chemicals inside the average home, leading to indoor air quality levels on par with a polluted major city, according to a study by researchers at the University of Colorado Boulder. Earlier post.).

demonstrated a measurement approach to for urban air pollution mapping at 4–5 orders of magnitude greater spatial precision than possible with current central-site ambient monitoring. Air pollution varies very finely in space, and we can’t capture that variation with other existing measurement techniques. —Apte et al.
Similarly, air pollution has been linked with cerebrovascular disease, cancer and cardiovascular morbidity and overall mortality, attributed in part to an increased systemic inflammatory response to fine particles. Martha Billings, lead study author and associate professor of medicine at the University of Washington.
A new study led by Tokyo Institute of Technology (Tokyo Tech), Hokkaido University and the University of Washington explains why. We need to understand this multiphase chemistry in the atmosphere to design an efficient strategy to manage air pollution and accurately predict future air pollution and climate change impacts.

Catalytic converters have been used in the US since the 1970s as a way to clean up pollutants from vehicle exhaust. In the catalytic process, rare metals such as platinum, are used in a chemical reaction to convert carbon monoxide and other pollutants to non-toxic carbon dioxide, nitrogen, and water. —Yong Wang. Resources.
While the study finds an association between air pollution and atherosclerosis, researchers aren’t clear on why. For policy in the US, the focus should be on how to effectively control ozone concentration, which may be harder because it’s a secondary pollutant. —Meng Wang. —Meng Wang. —Meng Wang. Meng Wang, Paul D.
CHIE participants are exposed to one or several common air pollutants usually for a few hours at concentrations that are not expected to produce adverse responses. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants. 2009 to Oct.
A coalition of 11 states filed a lawsuit to compel the US Environmental Protection Agency (EPA) promptly to revise national air quality standards for air pollution involving soot. The EPA had failed to meet an October 2011 deadline for revising the existing standards. EPA last revised the standards in 2006.
