Solidification/Stabilization: A Remedial Option for Metal-Contaminated Soils
TL;DR: The solidification/stabilization (S/S) technique is the commonly adopted immobilization option to treat the contaminated soils, which employ additives to convert the hazardous waste to non-hazardous mass in accordance with the legitimate landfill provisions as mentioned in this paper.

Bioavalibility in Soils
TL;DR: This chapter reviews and discusses the commonly used phrase or concept “bioavailability” and concludes that a precise definition of bioavailability equally applicable to all different contaminated sites, contaminants and organisms is unlikely to be achieved.
In-situ remediation of Cd-polluted paddy soil by clay minerals and their effects on nitrogen,phosphorus and enzymatic activities
TL;DR: In this paper, an in-situ immobilization field demonstration of Cd-polluted paddy soil by palygorskite and sepiolite was conducted to investigate the immobilization effects according to a set of variables (grain yields and Cd concentration in brown rice; soil available Cd content,pH,hydrolyzable nitrogen, available phosphorus and soil enzymatic activities).

Acid activation of montmorillonite : Effect on structural and catalytic properties
TL;DR: Montmorillonite is a layered smectite clay with octahedral layers and acid activation replaces the interlamellar cations with protons, leaches Al +3 from octagonal layers resulting in increase of surface area, porosity and acidity as mentioned in this paper.
