Urban CO2 Domes May Enhance May Increase Ozone and PM, With Accompanying Increase in Mortality

Green Car Congress

In a new study published online 10 March in the ACS journal Environmental Science and Technology , however, Stanford University professor Mark Jacobson finds that local CO 2 emissions in isolation may increase local ozone and particulate matter. Although the health impacts of such changes are uncertain, he notes, they are of concern.

Berkeley study identifies diesel as main source of vehicular secondary organic aerosols

Green Car Congress

A study led by researchers at UC Berkeley has found that diesel exhaust forms about seven times more secondary organic aerosols (SOA) than gasoline exhaust for the same mass of unburned fuel emissions and, given emission factors, can be expected to form 15 times more SOA than gasoline per liter of fuel burned.
