Untreated industrial effluent is a major source of environmental pollution of lead (Pb). Most of the Pb used in ceramics, glass, non-household paints and pigments, acid batteries, printed circuit boards, ammunition, and other products comes from industrial effluents (Grossman et al. 1999).Salts, oxides, and sulfurides are some possible forms of Pb.
