DOE: despite 13% rise in VMT from 2002-2015, pollution down significantly

Green Car Congress

Despite an increase in vehicle miles traveled (VMT) of 13% from 2002 to 2015 (the latest year for which data are available), the total amount of airborne pollutants emitted from highway vehicles has declined considerably, according to the US Department of Energy (DOE).

Study finds association of pollution with increased risk of psychiatric disorders

Green Car Congress

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.

NIH study links air pollution to increase in newborn intensive care admissions

Green Car Congress

Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the US National Institutes of Health (NIH). Short-term exposure to most types of air pollutants may increase the risk for NICU admission.

Comparative study finds that B20 increases emission rates of a number of pollutants in both light- and medium-duty diesel engines at idle

Green Car Congress

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. L/2002 calibration and 6.4 Unregulated pollutants also include ozone precursors and bioaccumulative and toxic compounds. L/2004 calibration engines.

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

Study Measures Impact of Biodiesel on Non-Regulated Pollutants in Heavy-Duty Engine

Green Car Congress

A team from the US National Renewable Energy Laboratory and the Colorado School of Mines has measured gas phase and particle-associated non-regulated pollutant emissions from a heavy-duty engine operating both with and without a catalyzed DPF and operating on biodiesel fuel. Experiments were conducted on a 2002 model year 5.9
