Geochemical inheritance of soils that develop from volcanic rocks (Navarra, Western Pyrenees)

Geochemistry of Mercury Along a Soil Profile Compared to Other Elements and to the Parental Rock: Evidence of External Input

“…A suite of elements (Al, Ga, V, Ti, Sc, Y, Nb, Zr, Th) is less mobile during weathering (Nesbitt 1979;Faure 1998;van der Weidjden and van der Weijden 1995;Teutsch et al 1999;Kurtz et al 2000;Lasheras Adot et al 2006;Ma et al 2007). The relative immobility of the elements is not expected to depend critically on the proxy element, but absolute differ- ences in the coefficients of mass transfer do.…”

Heavy metal concentrations in soils from a remote oceanic island, Fernando de Noronha, Brazil

“…However, prior to assessing contamination, it is necessary to determine the local pedo-geochemical background of heavy metals (Baize andSterckeman 2001, Salonen andKirsti 2007). The geochemical inheritance of the parent rock can be evaluated by comparing soils developed from rocks of distinct composition under similar climatic conditions (Horckmans et al 2005, Lasheras Adot et al 2006. On the other hand, the variation of concentrations with depth and the degree of enrichment/ depletion of an element in relation to the parent rock 1194 SONIA M.B.…”

Influence of geological setting on geochemical baselines of trace elements in soils. Application to soils of South–West Spain

“…Since the parent material strongly influences soil chemical properties (Palumbo et al, 2000;Salminen and Gregorauskiene, 2000;Lasheras et al, 2006), a geochemical baseline must be determined separately for each element in geologically different regions. Otherwise, the limiting values (action limits) for contaminated soil may be lower than the natural concentrations (backgrounds) over wide areas (Salminen and Tarvainen, 1997).…”
