“…In spite of these reactions proceeding simultaneously, availability of metals and their behaviour in the soil have been reported to be controlled by sorption mechanism 5 . The concentration of metal ions and complexes in the soil solution is regulated by adsorption process and hence can majorly influence their absorption by plant roots 6 . Heavy metals like cadmium and lead may exhibit high toxicity because of their ability to solubilize in water.…”

The study investigates the sorption of cadmium (Cd) and lead (Pb) by Nsukka urban soils, a Nigeria soil classified as an ultisol soil of tropics. Laboratory batch technique was utilized to investigate the effect of pH, temperature, contact time, and concentration on the adsorption process. Results showed that adsorption efficiency of the soils for Cd2+ and Pb2+ increased with increase in pH, temperature, and contact time but decreased with increase in concentration. The data from adsorption study was fitted to the Langmuir, Freundlich and Temkin adsorption isotherms, and results revealed that Langmuir isotherm fitted most satisfactorily. On the basis of the obtained maximum adsorption capacity (qmax) from the Langmuir model, the affinity of Cd and Pb for the studied soil was Pb2+ > Cd2+. Pseudo-second order (r2 ≥ 0.995-0.999) best described the kinetics of the sorption process for the metal ions in the soil.

“…Csorba et al silicate minerals (Shuman 1975;Ford and Sparks 2000;Voegelin et al 2002;Bradl 2004).The effect of soil pH on the pseudo total PTE content was weak (Zn, Co and Cr) or non-detectable (Cu) in this study. Similarly, the clay, CEC, OM, pH and CaCO 3 contents were the main factors regulating Ni retention in the studied soils (Mellis et al 2004;Adhami et al 2008;Ramachandran and D'Souza 2013). Our study shows that in the case of nickel this relationship is twice stronger with PC1 than with PC2.…”

The aim of this paper is to examine the relationship between soil properties and potentially toxic element contents of arable soils based on the dataset of the Soil Information and Monitoring System in Hungary. Nine potentially toxic elements (As, B, Cd, Co, Cr, Cu, Ni, Pb, Zn) were compared with selected soil parameters. We carried out grouping of related soil properties by principal component analysis. The method was suitable to describe the relationship within groups of the soil properties. We studied correlations of the resulting components and potentially toxic elements. The change of Ni content was influenced by the physical properties of the soil (e.g. clay content, field capacity, R = 0.67). Boron is the only one of the examined elements that indicates significant positive correlation with saline-alkali (R = 0.21) parameters. Zn, Co and Cr behaved very similarly; their correlation with components 1 and 2 were the closest.

“…reported that soil pH was found to play the most important role in determining metal speciation, solubility from mineral surfaces, movement and bioavailability of metals in the soil solution. The Entisol soil used in this study had higher pH and OM content according to Inceptisol soil Ramachandran and D'Souza (2013). determinate that Ni adsorption capacity of the soil increased with an increase in pH of the soil.…”

In this study, the effects of gyttja on some soil properties in two different nickel-contaminated soils (Inceptisol and Entisol) were investigated. This study was conducted with the application of three levels of gyttja (0, 5 and 10%) in two different soils (Inceptisol and Entisol) contaminated with Ni at three levels of concentration (0, 40 and 80 mg kg -1 ) in a factorial experimental design with three replications. Some soil properties showed differences in different nickel and gyttja applications. Soil nickel content significantly (P < 0.01) increased in nickel-contaminated soils. Soil organic matter and phosphorus contents in gyttja applicated soils were found to reach higher levels compared to those without gyttja application.
