TLDR
Given the costs of phosphate treatment, the use of biogenic phosphate sources, such as bone meal, may be a more environmentally sustainable approach toward this end, and the success and sustainability of applying phosphate as a BMP in firing range soils remain questionable.About:

Precipitation, adsorption and rhizosphere effect: The mechanisms for Phosphate-induced Pb immobilization in soils-A review.
Guangming Zeng,Jia Wan,Danlian Huang,Liang Hu,Chao Huang,Min Cheng,Wenjing Xue,Xiaomin Gong,Rongzhong Wang,Danni Jiang +9 more
TL;DR: Three principal mechanisms may be responsible for P-induced Pb immobilization, including direct precipitation, ion-exchange (or substitution) effect and liming effect, and the adsorption of Pb are discussed.

Phosphates for Pb immobilization in soils: a review
TL;DR: In this article, the identification of pyromorphite in phosphate amended soils has been carried out by different non destructive techniques such as X-ray diffraction, scanning electron microscopy coupled with energy dispersive Xray spectroscopy, Xray absorption fine structure and electron microprobe analysis, the effectiveness of in situ Pb immobilization has also been evaluated by selective sequential extraction, by toxicity leaching procedure and by a physiologically based extraction procedure simulating metal ingestion and gastrointestinal bioavailability to humans.

Use and understanding of organic amendments in Australian agriculture: a review
TL;DR: A wide range of organic amendments (OA) is currently available to Australian farmers, but the widespread adoption of OA in Australia has been limited, due in part to the high application rates required to produce agronomic benefits, a lack of consistency in the composition of some products, a poor public perception of their utility, and an unbiased scientific research into the agricultural potential of these products.

Isolation of phosphate solubilizing bacteria and their potential for lead immobilization in soil.
Jin Hee Park,Nanthi Bolan,Nanthi Bolan,Mallavarapu Megharaj,Mallavarapu Megharaj,Ravi Naidu,Ravi Naidu +6 more
TL;DR: The ability of PSB to solubilize P, promote plant growth, and immobilize Pb can be used for phytostabilization of Pb contaminated soils.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.
Journal ArticleDOI
Estimation of lead and arsenic bioavailability using a physiologically based extraction test
TL;DR: The Physically Based Extraction Test (PBET) as discussed by the authors is an in vitro test system for predicting the bioavailability of metals from a solid matrix and incorporates gastrointestinal tract parameters representative of a human (including stomach and small intestinal pH and chemistry, soil-to-solution ratio, stomach mixing and stomach emptying rates).

In situ lead immobilization by apatite
TL;DR: It is hypothesize that Pb was immobilized by dissolution of hydroxyapatite and precipitation of hydroxypyromorphite [Pb 10 (PO 4 ) 6 (OH) 2 ]

Lead immobilization from aqueous solutions and contaminated soils using phosphate rocks.
TL;DR: The results strongly demonstrate that phosphate rocks may provide a cost-effective way to remediate Pb-contaminated water, soils, and wastes.

Evaluation of chemical immobilization treatments for reducing heavy metal transport in a smelter-contaminated soil.
Nicholas T. Basta,S.L. McGowen +1 more
TL;DR: Three chemical immobilization materials, agricultural limestone (AL), mineral rock phosphate (RP), and diammonium phosphate (DAP), were evaluated using solute transport experiments to determine their ability to reduce subsurface heavy metal transport in a smelter contaminated soil.
