Anthropogenic iron trace

Ca3(P04)2. Rapid sorption of iron by coastal sludge was observed after authorized discharge of Fe from an English nuclear power station, and re-mobilization of these anthropogenic iron traces was slow (Warwick etal. 2001). Correspondingly, the industrial Fe, Cr, and Ni load was associated with aluminum-silicate lattice in sediments of a Greek river estuary (Dassenakis et al. 

The mercury burden of the environment derives predominantly from natural sources [3]. Input into the atmosphere occurs by degassing of the earth s crust and emissions from volcanoes and by soil erosion into the surface waters. Mining is not the only anthropogenic source for mercury. The ubiquitous occurrence of traces of mercury in the whole earth s crust leads via the combustion of fossil fuel, the smelting of iron and other metals, as well as the production of cement to the release of large quantities of mercury vapor into the atmosphere and in this way increases the total amount of mercury in the ecosphere [4,5]. 

Major and trace elements in particulate matter can be classified as natural (Na, Mg, K, Ca, Si, Al, Mn, etc.) or anthropogenic (V, Cr, Mn, Ni, Cu, Zn, Cd, Pb, etc.). The principal anthropogenic emission sources are attributed to fossil fuels Cr, Mn and Sb are good markers for this source as they are present in coal, while V, Ni and Pb are emitted by fuel oil combustion. Industrial processes and non-ferrous mineral extraction are important sources for Cd, Zn, Cu and Hg, while elements like Ni, Zn, Pb and Cu are emitted during industrial processing of iron, cast iron and steel.
