Study finds heavy-petroleum fuels raising vanadium emissions; human emissions outpacing natural sources by factor of 1.7

Green Car Congress

Human emissions of vanadium to atmosphere now exceed natural sources by a factor of 1.7 and are destined to rise significantly with the use of heavy oils, tar sands, and bitumen as combustion sources. Vanadium is a trace metal found in many earth materials, including petroleum and coal.
