“…Heavy metals availability Addition of organic amendments to contaminated soils has been widely used to reduce toxicity and availability of heavy metals (Gadepalle et al, 2007). In this study, addition of BC to shooting range soil caused a significant decrease in TCLP-Pb up to 78.5% with 30% BC application (Fig.…”

Heavy metal remediation in shooting range soil is a challenge over the world. The excessive Pb accumulation in the soil can deteriorate soil quality and fertility. The objectives of this research were to evaluate the efficiency of biochar (BC) in improving the physicochemical and biological properties of the soil and to evaluate its effect on Pb availability in a military shooting range soil. Sandy loam soil was collected from shooting range of Gyeonggi Province, South Korea and was incubated for 30 days with different application rates (0-30% w w -1 ) of BC. The results showed that the addition of BC increased aggregate stability, nitrogen (N) and phosphorus (P) contents, and enzyme activities in soil. Sequential extraction showed that residual and organic bound fractions in the soil amended with BC increased by 33.1 and 16.7%, respectively, and the exchangeable fraction decreased by 93.7% in the soil amended with BC, compared to the unamended soil. We concluded that the application of BC could not only improve physicochemical and biological soil qualities but also stabilize Pb in a shooting range soil.

“…The immobilizing ability of RM (Gadepalle et al, 2007, Summers et al, 1993) may contribute to the nutrient scarcity over the long term. For example, Snars et al (2002) reported that environmental stress, such as drying or the addition of microbial suppressants could mitigate the effect of the red mud in decreasing P availability.…”

“…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.

“…Calcium carbonate and calcium oxide-bearing materials are commonly incorporated into soils for remediation purposes (Madejón et al 2002). Among them, paper mill, a by-product from de-inking of paper, contains a considerable proportion of calcium carbonate and its addition has been shown to diminish the mobile fractions of metals in soils (Gadepalle et al 2007;6 Méndez et al 2009). Furthermore, its recycling constitutes a very valuable alternative to minimise its land disposal.…”

Esta es la versión de autor del artículo publicado en: This is an author produced version of a paper published in: El acceso a la versión del editor puede requerir la suscripción del recurso Access to the published version may require subscription AbstractSeveral amendments were tested on soils obtained from an arsenopyrite mine, further planted with Arrhenatherum elatius and Festuca curvifolia, in order to assess their ability to improve soil's ecotoxicological characteristics. The properties used to assess the effects were: soil enzymatic activities (dehydrogenase, β-glucosidase, acid phosphatase, urease, protease and cellulase), terrestrial bioassays (Eisenia fetida mortality and avoidance behavior), and aquatic bioassays using a soil leachate (Daphnia magna immobilisation and Vibrio fischeri bioluminescence inhibition).The treatment with FeSO4 1% w/w was able to reduce extractable As in soil, but increased the extractable Cu, Mn and Zn concentrations, as a consequence of the decrease in soil pH, in relation to the unamended soil, from 5.0 to 3.4, respectively. As a consequence, this treatment had a detrimental effect in some of the soil enzymatic activities (e.g. dehydrogenase, acid phosphatase, urease and cellulase), did not allow plant growth, induced E. fetida mortality in the highest concentration tested (100% w/w), and its soil leachate was very toxic towards D. magna and V. fischeri. The combined application of FeSO4 1% w/w with other treatments (e.g. CaCO3 1% w/w and paper mill 1% w/w) allowed a decrease in extractable As and metals, and a soil pH 3 value closer to neutrality. As a consequence, dehydrogenase activity, plant growth and some of the bioassays identified those as better soil treatments to this type of multicontaminated soil.
