A new study led by University of Chicago researchers finds an association between exposure to environmental pollution and an increase in the prevalence of neuropsychiatric disorders. Our studies in the United States and Denmark show that living in polluted areas, especially early in life, is predictive of mental disorders.
A new study led by researchers at the University of Michigan compared regulated and unregulated emissions from both light-duty passenger car (1.7 They found that the level of emissions of regulated and unregulated pollutants in diesel exhaust depends on fuel, load, engine calibration, and exhaust aftertreatment 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. Repeated scans were done for nearly all participants between 2002 and 2005; for a subset of participants between 2005 and 2007; and for half of all participants between 2010 and 2012.
A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. Even though the CO 2 enhancements over background were comparable in the two years, about 25 ppm in 2002 and 35 ppm in 2010, the ?CO/?CO2 CO2 ratio for this flight track segment decreased from 24.5
Chan School of Public Health suggests that long-term exposure to traffic-related pollution significantly increases the risk of pediatric asthma, especially in early childhood. Fine PM originates from fuel combustion, including traffic, power plants, and other pollution sources. —corresponding author Mary B.
In a paper published in the American Journal of Respiratory and Critical Care , researchers report that children exposed to higher levels of air pollution—even if relatively low—including fine particulate matter (PM 2.5 ) and soot (black carbon), had worse lung function than those living in less polluted areas. mL; -43.9,
Researchers from Rice University and the US Environmental Protection Agency (EPA) report in a paper in the journal Atmospheric Chemistry that particularly in Northeastern cities, ozone levels dropped even beyond what was anticipated by cutting emissions of NO x from 2002 to 2006. from 2002 to 2006. Earlier post.).
With increasing pressure from air pollution, oil consumption and congestion, China is compelled to reinvent propulsion technologies. … The first target (1999-2002) was compressed natural gas (CNG), liquid petroleum gas (LPG) and other combustion alternative fuel vehicles (CAFVs), in a program called the Clean Auto Auction. Zhixin Wu.
A shift from gasoline to diesel engines following previous and upcoming European emission standards is consistent with long-term climate mitigation efforts, according to a new analysis by researchers from CICERO (Center for International Climate and Environmental Research, Norway), the University of Oslo and ETH Zurich.
A team from Carnegie Mellon University (CMU) has characterized the intermediate volatility organic compound (IVOC) emissions from on-road gasoline vehicles (LDGVs) and small off-road gasoline engines (SOREs). The relationships between IVOCs and other pollutants were examined to develop methods for estimating IVOC emissions from existing data.
But theyve needed definitive proof that PHEVs wont increase pollution. CA, NY, MA and other states have had Zero-Emission Vehicle programs since the early 1990s because battery electric vehicles in those states, taking into account power plants, are far cleaner than gasoline cars in reducing urban air pollution and smog. The GREET 1.6
Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid. For more on plug-in hybrids and V2G, see CalCars Resources , University of Delaware V2G Research Center , and papers from a June 2005 conference in Seattle. How can I help?
Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. This work in the MESA Air study was led at the University of Washington.
A study lead by a team from the University of Southern California has found that higher exposure to early life near-road air pollution (NRAP) increased the rate of change of childhood body mass index (BMI) and resulted in a higher attained BMI at age 10 years that were independent of later childhood exposures. —Kim et al.
A study by a team of researchers from China and the US has shown that shipping emissions in East Asia accounted for 16% of global shipping CO 2 in 2013, compared to only 4–7% in 2002–2005. Attention on ships and ports has increased as seaborne trade has grown significantly in recent decades.
Jacobson first showed in 2000 that black carbon was the second-leading cause of global warming after carbon dioxide in terms of radiative forcing and, in 2002, that its control was the most effective method of slowing warming. Further, controlling soot will significantly reduce particulate air pollution deaths. Earlier post.).
May, 2009 : Testifying at a public hearing conducted by the US Environmental Protection Agency (EPA), Stanford University professor Mark Jacobsen urged the EPA to incorporate black carbon into calculations of greenhouse gases. Emissions from ocean-going ships which burn minimally refined bunker fuel are primary sources of black carbon.
The prototype vehicle, called Project PUMA (Personal Urban Mobility and Accessibility), is designed to ease congestion and pollution problems in cities. He started at CNET News in 2002, covering IT and Web development. A PUMA runs on lithium ion batteries, can reach 35 miles per hour, and can travel up to 35 miles between charges.
The Think City was short-lived in the States with production halting in 2002 after just 1005 cars had been assembled. Several global indicators on the supply of oil and the known carbon pollution environmental damages its caused all lead us to find cleaner ways of transportation. safety requirements. They will not meet my needs.
