The Health Effects Institute (HEI) has launched two new studies funded under RFA 21-1, Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions. The new studies are: Improved Characterization of the Real-World Contributions and Impacts of Non-tailpipe Particulate Matter Emissions ,” led by Greg Evans, University of Toronto.
About 4 million children worldwide develop asthma each year because of inhaling nitrogen dioxide (NO 2 ) air pollution, according to an open-access study published in The Lancet Planetary Health by researchers at the George Washington University Milken Institute School of Public Health (Milken Institute SPH). Achakulwisut et al.
This study builds on the 2007 Environmental Assessment of Plug-in Hybrid Electric Vehicles by EPRI and NRDC ( earlier post ), which showed that plug-in hybrid electric vehicles could contribute to reductions in national greenhouse gas emissions, while also leading to improved air quality. —Mike Howard, EPRI president and CEO.
Consumer products such as shampoo, cleaning products and paint now contribute as much to emitted volatile organic compounds (VOCs) in cities as tailpipe emissions from vehicles, according to a new study led by NOAA. Total VOC emission factors for end uses of petrochemical sources in the study. de Gouw, Stuart A.
The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. —Caroline Womack. Womack, C. McDuffie, E. Edwards, P. Docherty, K.
The first study to conduct a comprehensive evaluation of lifetime exposure to new technology diesel exhaust (NTDE)—i.e., The study exposed laboratory rats 80 hours a week, for up to 30 months, to emissions from a heavy-duty diesel engine meeting 2007 US EPA standards using new filters and other control technology.
Between 2002 and 2010 alone, the concentration of VOCs dropped by half, according to a new study by NOAA scientists and colleagues, published in the AGU’s Journal of Geophysical Research. The reason is simple: cars are getting cleaner. The difference was amazing. —lead author Carsten Warneke, Ph.D., —Warneke et al.
A study by NASA scientists and their colleagues at Dalhousie University (Canada) and NOAA based on satellite data has found a significant correlation of surface nitrogen dioxide (NO 2 ) with population in the three countries and one continent examined: United States (r = 0.71), Europe (r = 0.67), China (r = 0.69), and India (r = 0.59).
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.).
A longer service life reduces the fleet’s turnover rate to cleaner, lower-emitting engines, therefore increasing future-year emission estimates. A related study by DTF and EDF confirms that upgrading workboats to the newest-model clean diesel engines delivers the greatest emissions improvements for the lowest cost.
are based on scores of national and international epidemiological, animal and human exposure studies. In addition to ozone and particulate matter, the other pollutants are lead, carbon monoxide, nitrogen dioxide and sulfur dioxide. The ATS recommended standards for O 3 and PM 2.5
The data were gathered during the CalNex 2010 field study organized by ARB and the National Oceanic and Atmospheric Administration (NOAA). The California data were compared to ship-plume measurements made by NOAA near the Port of Houston, Texas in 2006.
The basic question addressed, which appears on the study homepage (epri-reports.org) is this: How would air quality and greenhouse gas emissions be affected if significant numbers of Americans drove cars that were fueled by the power grid? And the grid is getting cleaner and more renewable every year. billion metric tons.
Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
Accordingly, there have been a number of recent studies working to assess the impact of non-exhaust emissions from EVs and suggesting a regulatory or policy response (e.g., A 2014 study by Weinbruch et al. Compared to earlier studies, Weinbruch et al. A new Rotterdam-specific study by a pan-European team (Tobollik et al.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation. cents to 10 cents per kilowatt-hour, based on previous modeling studies. cents per kwh.
The study was published 8 June in the open access IOP journal Environmental Research Letters. Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data).
A new study from UC Berkeley confirms what EV fans already know: EV adoption does, in fact, make the air cleaner. Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not in the foreseeable future.
And so back in, I believe it was the 80s, it might have been earlier than that, Paul Knutson who famously identified the ozone whole problem, he put forward the idea that putting material in the stratosphere might be an interesting way to reflect sunlight to cool the planet. And that was based on observations of volcanoes.
Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs. Besides a danger to breathe, ozone lowers crop yields.
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, like i said in the first place, for me, this makes me think of one step in the right direction and makes me think of a greener cleaner future.
