Martinez-Martinez (b) Keywords: Heavy metals; Salts; Mobility; Ionic strength; Soil Abstract: a* An increase of ionic strength increases the concentration of Pb, Cu, Cd released. a* An increase of ionic strength promoted a higher release of Cd than the others metals. a* An increase of total metal decreases the % of Pb and Cu released upon salinization. a* Pb, Cd, Zn mobility was main regulated by competition with Ca.sup.2+ for sorption sites. a* The main mechanism regulating Cu mobility was the formation of Cu-sulfate.
