“…The main sorption surfaces are clay particles and organic matter (Römkens and Salmons, 1999;Kaschl et al, 2002). In the last three decades the mobility of many heavy metals has been studied in a wide range of soils, including acid (Simard et al, 1999;Cornu et al, 2001) and alkaline soils (Walter and Cuevas, 1999;Navarro-Pedreño et al, 2003).…”

“…It is necessary, however, to assess the positive and negative consequences of this application (Navarro-Pedreño et al 2003). Negre et al (2006) described an experiment of fertilization of an urban park in Turin (North Italy) with a MSW compost at different application rates.…”

Sierra de Callosa have an area of 8 km 2 and a maximum altitude of 566 masl. Geologically, it is found to be primarily comprised of carbonated rocks. Mine spoils coming from limestone quarries extraction are often used in the working reclamation process. These materials could be actually employed profitably once conveniently amended with organic matter. A study on the temporary evolution of nutrients and several physical-chemical parameters in a mineral waste amended with municipal solid waste (MSW) compost has been carried out. The effect of incorporating such waste to mine spoils in an arid gravel quarry has been studied, quantifying the temporal evolution of nutrients and several physical-chemical parameters in the mixture. Three plots have been prepared with mine spoils proceeding from a limestone quarry located in the south of the province of Alicante (municipality of Redován). These plots have been amended with 3 kg/m 2 of MSW compost. Texture, pH, electrical conductivity, oxidizable organic matter, N-Kjeldahl, available P, Na, K, Ca, Mg, Fe, Mn, Cu and Zn were analysed. The results reflected the contribution of nutrients to the substrate after the MSW addition. The variability of the information indicated the heterogeneity of the MSW composition, as well as the difficulty of obtaining a homogeneous MSW mixture-mineral waste.

“…In general, the toxicity of Cd in soil increases as its mobility increases. Previous studies have shown that the mobility of potentially hazardous trace metals in agricultural soils is closely related to the chemical transformations of these elements in the soil environment (Sposito et al 1982;Navarro-Pedreño et al 2003;Lafuente et al 2008). It is therefore necessary to know the chemical forms of Cd in soils and the factors influencing the conversion of its chemical forms in soil.…”

“…In the past three decades, the mobility of Cd has been studied in diverse soils, including acid (Simard et al 1999;Cornu et al 2001) and alkaline (Walter and Cuevas 1999;Navarro-Pedreño et al 2003) soils. Nevertheless, there is limited information on the chemical transformation of Cd as a result of soil acidification caused by factors other than acid rain in calcareous soils with high Cd background concentrations.…”

Abstract. Calcareous soils with high background cadmium (Cd) levels are widely distributed in south-west China and soil acidity is a major environmental problem. However, little effort has been made to study the changes in chemical speciation as affected by soil acidification other than by acidic rain. In the present study, we investigated the impact of mono-ammonium phosphate (MAP) and phosphoric acid on soil pH and chemical transformation of Cd in calcareous soils. Calcareous soils collected from south-west China were treated with three concentrations (0.1, 0.2 and 0.4 mol kg -1 soil) of MAP and phosphoric acid, and without the addition of acidifying agent, before being incubated at 25 AE 28C near field capacity moisture content for 60 days. The chemical forms of Cd in the soils were determined by the Tessier sequential extraction scheme. The concentration of Cd in the form bound to iron and manganese oxides (Cd FeOx+MnOy ) decreased significantly with increasing levels of the two acidifying agents, but the concentration of exchangeable Cd (Cd Ex ) exhibited a significant increase, indicating that the two acidifying agents can effectively promote the transformation of Cd FeOx+MnOy to Cd Ex . MAP may promote the same amount of Cd FeOx+MnOy to Cd Ex as phosphoric acid at the same rate of addition, but the soil pH clearly differed, implying that an increase in water-soluble P with addition of acidifying agent may be one major factor affecting the chemical transformation of Cd. MAP and phosphoric acid should be used carefully as sources of water-soluble phosphorus for calcareous soils with high background concentrations of Cd.
