Fig. 5: Graphical illustration of the emission from natural and anthropogenic sources to atmospheric iron.
From: Stable iron isotopic composition of atmospheric aerosols: An overview
The δ56Fe values of iron sources, including surface sea water52,134, terrestrial dust125, burning event140, steel manufacturing142,147, coal fly ash128,146, solid waste incineration141,146 and exhausted gasoline141, are according to published literature (There are no data for volcanic ash and wild fires, etc.). Iron isotopic variations in both fine and coarse particles in marine71,127,128,148,152,155 and urban aerosols147,148,150 are also listed.
