Pollution exposure was estimated for the area around each child’s home for each trimester of their mother’s pregnancy and during their first year of life.
Despite these successes, sulfate levels in the atmosphere have declined more slowly than sulfur dioxide emissions, especially in wintertime. This unexpected phenomenon suggests sulfur dioxide emission reductions are less efficient than expected for cutting sulfate aerosols. These trends are expected to continue.

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).
This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. Michael Diamond/University of Washington.
A new report from MIT’s Joint Program on the Science and Policy of Global Change suggests that a tax on carbon emissions could help raise the money needed to reduce the US deficit, while improving the economy, lowering other taxes and reducing emissions. in support of a carbon tax in a February opinion piece in The Washington Post.
pollution in the state. is especially burdensome in California and accounts for the greatest percentage of health impacts attributable to air pollution. MISR has other applications, including the ability to distinguish between different types of particle pollution. to predict PM 2.5 Most monitors do not track individual PM 2.5
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.).
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 Chris Gregoire and legislative leaders have introduced a Green Jobs and Climate Action legislative package that proposes investments totaling $455 million in the next biennium for energy-reducing transportation projects, energy efficiency projects, green buildings and clean-energy technology.
Long-term exposure to particulate air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. Participant-specific pollutant concentrations averaged over the years 2000–10 ranged from 9.2–22.6 The study is published in The Lancet. and NO x between 1999 and 2012. μg PM 2.5 /m
These increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study. Tropospheric ozone is an important source of the hydroxyl radical, an oxidant that breaks down most pollutants and some greenhouse gases. Cooper, Ph.D.
The goal is to ensure that 100% of all new medium- and heavy-duty vehicle sales be zero emission vehicles by 2050 with an interim target of 30% zero- emission vehicle sales by 2030. Medium- and heavy-duty trucks are a major source of harmful smog-forming pollution, particulate matter, and air toxics.
The US Environmental Protection Agency (EPA) announced the availability of grant funding to implement projects which reduce emissions from the nation’s existing fleet of older diesel engines. Region 10 (Alaska, Idaho, Oregon, Washington) will accept applications requesting up to $1,000,000 in grant funds. Background.
and Mexico’s Ministry of Environment and Natural Resources Undersecretary Rodolfo Lacy and Mexican National Forestry Commission Director General Jorge Rescala Pérez signed an agreement to help reduce greenhouse gas emissions (GHGs). Strengthening fuel and truck efficiency standards and supporting green freight initiatives.
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.
While the study finds an association between air pollution and atherosclerosis, researchers aren’t clear on why. The EPA reports that particulate matter concentrations have decreased across the nation as efforts are made to reduce vehicle emissions and use clean energy. —Meng Wang. —Meng Wang. Meng Wang, Paul D.
In-use testing of three light duty diesel vehicles—certified to US-EPA Tier2-Bin5 and California LEV-II ULEV emissions limits— found a wide variation in real world emissions performance relative to the regulatory limits. diesels and one 3.0L diesel) over pre-defined test routes exhibiting diverse driving conditions.
A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. Most emission inventory calculations use a computer model to estimate the fleet’s emissions.

UC stands for uncontrolled charging and CC stands for controlled charging.
In particular, the study led by Drew Shindell found that methane emissions have a larger warming impact due to those interactions than accounted for in current carbon-trading schemes or in the Kyoto Protocol. Shindell et al. Similar reactions influence the creation of nitrate aerosols.
Such reasons include advantages to the electrical grid such as load balancing and energy storage, increased jobs and economic development, reduced stormwater pollution and consumer savings. The Washington bill, drafted according to the legal path identified in the law review article, required all new cars to be electric by 2030.
The ACC regulations revise California’s Low Emission Vehicle (LEV) program (which includes both criteria pollutant and greenhouse gas (GHG) emission standards) as well as the Zero Emission Vehicle (ZEV) program. The updated ZEV, GHG, and LEVIII criteria emission standards regulations are covered under the ACC waiver.
Sightline Institute reports that drivers in the Northwest states of Idaho, Oregon, Washington used more gasoline last year, reversing a decade-long trend of declining personal gas consumption. Washington and Oregon saw per capita increases of less than 1%, which is a departure from the states’ nearly uninterrupted decline since 1999.
