In a recent study, MIT scientists have studied the impacts of air pollution from major sectors on the health of Americans. The results are a bit troubling - about 200,000 premature deaths are caused per year in the U.S. due to changes in fine particles (diameter less than 2.5 microns) concentrations, and about 10,000 deaths due to changes in ozone concentrations from the emissions from combustion sources.
The study showed that the largest contributors for both pollutant-related mortalities are road transportation causing ~ 58,000 deaths per year, followed by power generation (~57,000), and industrial emissions (~43,000).
The researchers also mapped local emissions in 5,695 U.S. cities which showed the highest emissions-related mortality rate in Baltimore, where 130 out of every 100,000 residents likely die in a given year due to long-term exposure to air pollution.
