Effects of Aqueous Al, Cd, Cu, Fe(II), Ni, and Zn on Pb Immobilization by Hydroxyapatite

Effects of Microbial and Phosphate Amendments on the Bioavailability of Lead (Pb) in Shooting Range Soil

“…In many cases, the exudate chemistry that underlies the function is poorly understood, particularly regarding complexation of inorganic pollutants such as Pb. Numerous laboratory and field studies have clearly demonstrated the effectiveness of apatite addition in reducing the solubility and/or bioavailability of Pb in contaminated soils and sediments (Ma et al 1993;Ma et al 1994), as well as other metals and radionuclides (Arey et al 1999;Seaman et al 2001). Studies have also demonstrated the effectiveness of biosurfactants in soil bioremediation (Sandrin et al 2000;Kosaric 2001;Bodour 2003).…”

Estimation of Heavy Metal in Vegetables From Different Market Sites of Tribal Based Ranchi City Through ICP-OES and to Assess Health Risk

“…Regulation, handling and bioremediation of hazardous materials require an assessment of the risk to some living species other than human being, or assessment of hazard to the entire ecosystem. Heavy metal accumulation in soils is of concern in agricultural production due to the adverse effects on food quality (safety and marketability), crop growth (due to phytotoxicity) (Ma et al, 1994;Msaky and Calvert, 1990;Fergusson, 1990) and environmental health (soil flora/fauna and terrestrial animals). The mobilization of heavy metals into the biosphere by human activity has become an important process in the geochemical cycling of these metals.…”

Removal of Fe3+ from Aqueous Solution by Natural Apatite

“…Iron ions are attracting wide research attention since they are found in many manufacturing industries such as coatings, car, aeronautic and steel industries [9]. Many absorbents have been reported for removal of iron ions (Fe 2+ or Fe 3+ ), such as bacterias [9,10], chitin [11], palm fruit bunch and maize cob [12], Bengal gram husk [13], tur dal husk [14], eggshells [15], ash [16], sawdust [17], activated carbon [18], natural zeolite [19], bentonite and quartz [20], and apatite [21][22][23].…”
