MIT study says combustion emissions cause ~200,000 premature deaths/year in US; vehicles and power generation top sources

Green Car Congress

In a state-by-state analysis, the researchers found that California suffers the worst health impacts from air pollution, with about 21,000 early deaths annually, mostly attributed to road transportation and to commercial and residential emissions from heating and cooking. 2000 (90% CI: 0–4,000) early deaths from ozone, according to the study.

Study links air pollution to increased emergency department visits for heart and lung disease

Green Car Congress

New research by George Mason University found that exposure to certain air pollutants is linked to increased emergency department (ED) visits for respiratory and cardiovascular diseases. We estimated associations between twelve ambient air pollutants of both primary (e.g. The study is published in the journal Environment International.

Georgia Tech study finds link between sulfate, metallic particles from vehicles and adverse health impacts

Green Car Congress

For the study, the team collected size-segregated ambient PM from a road-side and representative urban site in Atlanta, GA. Therefore, this kind of process will continue to play out in the future and will be an important consideration when we look at the health effects of particulate matter. —Fang et al. 6b06151.

Yale study finds that organic aerosols more complicated than previously thought

Green Car Congress

Yale researchers have found that organic aerosols—a type of air pollution—are much more complicated than previous studies indicated. Collected over three weeks at each site in the summer, samples were taken from a forest in Michigan, and from urban environments in Atlanta and New York City. —Jenna Ditto, a Ph.D.

First results from HEI/ACES murine study find few biologic effects from exposure to exhaust from new technology diesel engines

Green Car Congress

The study—a component of the Advanced Collaborative Engine Study (ACES)—is exposing rats and mice for 16 hours a day to emissions from a heavy duty diesel engine meeting 2007 US EPA standards that reduce emissions of fine particles and other pollutants by more than 90% from levels emitted by older engines.
