“…The translocation of heavy metals in wheat followed the order Cd > Pb, which indicated that heavy metals in soils were not evenly absorbed by plants and that translocation was not only related to the concentrations of heavy metals in soils. Similar results were reported by Castaldi et al (2009) who found that translocation for wheat and pea followed the order Cd > Pb. High Cd translocation was found in plants because of its similar properties to Zn (Liphadzi and Krikham 2006), and Cd translocation in wheat (Triticum aestivum L.) was regulated by Zn (Green et al 2003).…”

“…High Cd translocation was found in plants because of its similar properties to Zn (Liphadzi and Krikham 2006), and Cd translocation in wheat (Triticum aestivum L.) was regulated by Zn (Green et al 2003). Low translocation of Pb was found in plants because Pb was sequestered in the vacuole or cell walls in the root (Castaldi et al 2009), which was related to stability property of Pb in soil-plant system. Sanita di Toppi and Gabbrielli (1999) also reported that Pb was early recognized by the plant roots as a toxic compound, and sequestrated in the vacuole or in the cell walls, thus leading to low translocation in the shoots.…”

Purpose The aim of this study was to evaluate the effectiveness of soil amendments and foliar fertilizer on Cd and Pb immobilization in contaminated soils. Materials and methods A field experiment was conducted in contaminated soils, wherein four amendments (sepiolite (SE), single superphosphate (SSP), triple super phosphate (TSP), calcium magnesium phosphate (CMP)) in combination with one foliar fertilizer (ZnSO 4 ) were investigated to reduce Cd and Pb bioavailability in calcareous soils. Total Cd and Pb concentrations in wheat, soil, and amendments were determined using inductively coupled plasma mass spectrometry. Available concentrations of Cd and Pb in soils were extracted using diethylenetriamine pentaacetic acid. Results and discussion The results indicated that application of these amendments and foliar fertilizer significantly decreased Cd availability in soils and Cd accumulation in wheat (P < 0.05); however, the soil amendments plus Zn fertilizer did not significantly decrease Cd and Pb concentrations in wheat. Compared with the control, application of soil amendments effectively reduced the available Cd and Pb in soils by 25.69~54.13% and 9.86~42.14%, respectively. Accordingly, the reduction of Cd and Pb concentrations in wheat grain by the soil amendments was 20.68~41.38% and 23.68~55.26%, respectively.Conclusions Among all the treatments, the addition of SE + SSP and SE + CMP exhibited the most efficiency in reducing Cd and Pb availability, respectively, in the soil.

“…They explained this increase by the fact that RM reduced the toxicity of metals to microorganisms directly. In other studies, it was confirmed that beyond Biolog EcoPlate derived values other microbial parameters, such as fast-growing heterotrophic bacterial cell number, microbial abundance, the activity of selected enzymes (dehydrogenase, urease) were also improved after red mud treatment (Castaldi et al, 2009, Garau et al, 2007. Sprocati et al 2014 explained the high functional diversity of the metabolic profile of toxic metal polluted soil gained after Viromine™ (a red mud derived product) treatment as related with the increase in pH caused by its the addition.…”

“…Due to the combined presence of ferric, aluminium and tectosilicate-like compounds in red mud (Gadepalle et al, 2007), it is proved to be an effective amendment in reducing metal mobility in contaminated soils and stimulating microbial abundance, diversity and activity (Garau et al, 2007, Lombi et al, 2002, Gray et al, 2006, Bertocchi et al, 2006, Castaldi et al, 2009, Sprocati et al, 2014.…”

Red mud can be applied as soil ameliorant to acidic, sandy and micronutrient deficient soils. There are still knowledge gaps regarding the effects of red mud on the soil microbial community. The Biolog EcoPlate technique is a promising tool for community level physiological profiling. This study presents a detailed evaluation of Biolog EcoPlate data from two case studies. In experiment "A" red mud from Ajka (Hungary) was mixed into acidic sandy soil in soil microcosms at 5-50 w/w%. In experiement "B" red mud soil mixture was mixed into low quality subsoil in a field experiment at 5-50 w/w%. According to average well color development, substrate average well color development and substrate richness 5-20% red mud increased the microbial activity of the acidic sandy soil over the short term, but the effect did not last for 10 months. Shannon diversity index showed that red mud at up to 20% did not change microbial diversity over the short term, but the diversity decreased by the 10 th month. 30-50% red mud had deteriorating effect on the soil microflora. 5-20% red mud soil mixture in the low quality subsoil had a long lasting enhancing effect on the microbial community based on all Biolog EcoPlate parameters. However, 50% red mud soil mixture caused a decrease in diversity and substrate richness. With the Biolog EcoPlate we were able to monitor the changes of the microbial community in red mud affected soils and to assess the amount of red mud and red mud soil mixture applicable for soil treatment in these cases.

“…Similarly Castaldi et al [12] found that red mud application had a significant positive effect on bacterial number in Pb, Zn and Cd contaminated acidic soil. Lombi et al [10] observed also increasing microbial biomass volume on contaminated soil after red mud application.…”

A soil column experiment was set up to investigate the effect of red mud from Ajka (Hungary) on a typical soil profile from the concerned area. The chemical changes caused by the leachate of the red mud and the effects of these changes on living organisms were assessed. Ecotoxicological tests with Vibrio fischeri, Sinapis alba and Folsomia candida were performed and the number of aerobic heterotrophic microorganisms was determined. The total, plant available, exchangeable and water soluble fractions of Na, Mo, Cu, and Cr increased in the soil mostly due to their leaching from the red mud layer and partly to the increase of the pH and DOC concentration. The chemical changes had significant effects on the test organisms only in the 0 -30 cm soil layer except for F. candida that had a lower survival rate also in the 30 -50 cm soil layer. There were no severe toxic effects detected on the test organisms. Furthermore in case of the aerobic heterotrophic cell number and S. alba germination a stimulating effect was revealed. However, the red mud itself was toxic, therefore the performed ecotoxicology tests have justified the removal of red mud from the soil surface after the disaster.
