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.

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

Stanford Professor Urges EPA to Include Black Carbon in Endangerment Finding

Green Car Congress

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.).

USC study suggests early life exposure to near-road air pollution contributes to increased obesity risk in children

Green Car Congress

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.

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.

CMU team identifies IVOCs emissions from on-road gasoline vehicles and small off-road engines as important SOA precursors

Green Car Congress

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.
