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.
