Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

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.

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.

10-year study shows how air pollution fosters heart disease; accelerated plaque build-up in arteries

Green Car Congress

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.

Study: even relatively low levels of air pollution appear to affect a child’s lungs

Green Car Congress

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,

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 finds shipping emissions in East Asia contribute to up to 37.5K premature deaths each year

Green Car Congress

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.

Rice/EPA study finds ground-level ozone falling faster than CMAQ model predicted

Green Car Congress

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.
