Lead Ore Distribution

Pb – Lead

the distribution of lead in solution (Nelson et al. 1995). Although Pb is more soluble in non-calcareous soil below pH 5.2, it is adsorbed on iron oxides in preference to Cu and Zn (O'Day et al. 1998) and, therefore, does not migrate readily to groundwater (Martínez and Motto 2000). Lead concentrations in unpolluted rainwater and snow
