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. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

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 finds power law scaling relationship between urban population and NO2 pollution

Green Car Congress

The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. Even though larger cities are typically more energy efficient with lower per-capita emissions, more people still translates to more pollution.) ppb (India).

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

New NASA satellite images released this week demonstrate the reduction of air pollution across the US. Nitrogen dioxide is one of the six common pollutants regulated by the US Environmental Protection Agency (EPA) to protect human health. It’s also a good proxy for the presence of air pollution in general.
