“…The organic matter enrichment at certain depths may have been caused by the anthropogenic transformations of some areas that affected the distribution of organic matter within soil profiles. Such processes could be controlled by the content and inventory of mineral components and their physico-chemical properties in specific profiles (Huot et al 2014).…”

Long-term changes of As, Cd, Fe, Pb, Tl, Zn, Cl -, SO 4 2-, and PO 4 2-contents were calculated in topsoil samples and soil profiles in the vicinity of the Zn-Pb mine and processing plant at Bukowno, Poland. Evaluations were based on research results obtained in 1994-2014. Soil was described on the basis of hand specimens for which the following were determined: active and potential pH, organic matter content, moisture content, buffer properties, total metal content (HCl?HNO 3 3:1), forms of binding metals (using the BCR sequential extraction procedure), metal bioavailability (extraction by the 0.05 M EDTA solution), and water leaching of metals. Soil contamination was determined by the contamination factor and the pollution load index. The potential environmental risk was determined by the risk assessment code (RAC). Twenty-year-long research demonstrated the trend of decreasing metal content in topsoil. The sampling sites, selected in close vicinity of the flotation tailings dump, showed increasing contents of As, Pb, and Cd. The metal content in soil profiles revealed a significant decrease with time. Metal bioavailability, tested in all soil samples, indicated that the exchangeable forms were carriers of mainly Cd (up to 83%), Zn (up to 72%), and Pb (up to 60%) (the proportions refer to total metal contents), whereas As, Fe, and Tl were bound either with hardly movable forms or remained in the extraction residuum. The RAC showed medium to high environmental risks in soils, caused by the presence of Cd, Zn, Pb, and Tl.

“…The origin of the organic matter in the surface horizon of the polluted site is both anthropogenic (i.e. coming from the steel sludge) and biological (mainly of plant origin) (Huot et al 2014). The accumulation of organic matter at the soil surface appears to be due 1) to the soil structure, which would lead to the stabilization and accumulation of the soil organic matter at soil surface, like in andosols, and 2) to a lack of endogeic species (such as earthworms) that possibly limited the incorporation of soil organic matter to deeper soil levels (Cortet & Nahmani, unpublished results).…”

“…The discussion to follow is based on investigations of soils formed in different types of technogenic materials (e.g., construction debris, mine spoil, industrial sludge and ashes, excavated bedrock, stormwater sediments) reported in the literature and from the example of a Technosol developing on a former iron industry settling pond (blast furnace sludge) under forest cover and a temperate climate since ca. 60 y, previously studied (Huot et al, 2013a(Huot et al, , 2013b(Huot et al, , 2014a(Huot et al, , 2014bLucisine et al, 2015;Cortet et al, submitted). First, pedogenetic processes described in this range of soils were reviewed and particularities were compared to those occurring in natural soils.…”

“…Other important processes in the first steps of development of soils formed in technogenic materials are organic matter (OM) accumulation and humification at the surface (Bini and Gaballo, 2006). These processes have often been described in various vegetated technogenic materials, such as mine tailings (e.g., Schafer et al, 1980;Néel et al, 2003, Bini andGaballo, 2006;Uzarowicz and Skiba, 2011), industrial by-products (Zikeli et al, 2002;Grünewald et al, 2007;Huot et al, 2014b), construction debris (Howard et al, 2013), excavated bedrock (Scholtus et al, 2014) and dredged sediments (Vandecasteele et al, 2009). Accumulation depends on the nature and the density of vegetation cover, on the ability of materials to host plants (Néel et al, 2003), and on the climate (Sokolov et al, 2015).…”

Soils formed in technogenic parent materials are proliferating and their pedogenesis remains inadequately understood. Upon investigation of soils formed in various technogenic materials reported in the literature and of a Technosol developing on iron industry deposits, potential specificities of pedogenesis within technogenic materials are discussed. Analyses have shown that pedogenetic processes observed in these soils are similar to those occurring in natural soils. However, some particularities have been highlighted, such as the coexistence of processes rarely encountered simultaneously in natural environments or high rates of soil development during the first stages of weathering. Technogenic materials display highly diverse constituents, wide spatial variability, and temporal discontinuities as a result of human activities. These inherent features, in interaction with other soil-forming factors, may govern the pedogenesis by generating the following conditions: i) a high diversity of pedogenetic processes, including processes occurring usually in dissimilar climatic regions, ii) localized processes and distinct rates and orientations of soil development over short distance and iii) a succession and/or a superimposition of processes, constrained by the deposition of materials and human operations. This creates the potential for the simultaneity of processes coexisting rarely in natural soils developing in the same climatic region. These soils are likely to have a polycylic evolution and to evolve towards groups of soils other than Technosols, depending on the dominant processes. Further investigations of the processes and their potential interactions occurring in a larger range of soils formed in technogenic materials are required to better predict the evolution of these soils.
