soil contamination by potentially toxic elements and the associated human health risk in geo and anthropogenic contaminated soils a case study from the temperate region germany and the arid region egypt
Environmental Pollution, 2020Co-Authors: Jorg Rinklebe, Sabry M Shaheen, Vasileios Antoniadis, Eilhann E Kwon, Hocheol Song, Shanli Wang, Zengyei HseuAbstract:Abstract The aim of this study was to assess the soil contamination caused by potentially toxic elements (Al, As, Co, Cr, Cu, Fe, Mn, Mo, Ni, Se, V, and Zn) using various indices and the associated risk of human health for adults and children in selected soils from Germany (Calcic Luvisols, Tidalic Fluvisols, Haplic Gleysols, and Eutric Fluvisols) and Egypt (Haplic Calcisols, Sodic Fluvisols, and Eutric Fluvisols). Soil contamination degree has been assessed using indices such as contamination factor (CF), pollution load index (PLI), geo-accumulation index (Igeo), and enrichment factor. We also assessed the health risk for children and for male and female adults. Chromium, Cu, As, Mo, Ni, Se, and Zn in the German Fluvisols had high CF of >6, while in the Egyptian Fluvisols Se, Mo, As, and Al revealed a high CF. The PLI (1.1–5.2) was higher than unity in most soils (except for Tidalic Fluvisols), while the most important contributor was Se, followed by Mo and As in the Egyptian Fluvisols, and by Cr, Cu, and Zn in the German Fluvisols. The median value of hazard index (HI) for children in the studied soils indicated an elevated health risk (higher than one), especially in the German Fluvisols (HI = 4.0–29.0) and in the Egyptian Fluvisols (HI = 2.2–5.2). For adults, median HIs in all soils were lower than unity for both males and females. The key contributor to HI was As in the whole soil profiles, accounting for about 59% of the total HIs in all three person groupings. Our findings show that in the studied multi-element contaminated soils the risk for children’s health is higher than for adults; while mainly As (and Al, Cr, Cu, and Fe) contributed significantly to soil-derived health risk.

geochemical distribution of co cu ni and zn in soil profiles of Fluvisols luvisols gleysols and calcisols originating from germany and egypt
Geoderma, 2017Co-Authors: Jorg Rinklebe, Sabry M ShaheenAbstract:Abstract The geochemical fractionation and potential mobilization of Co, Cu, Ni, and Zn were studied in thirteen soil profiles originating from Germany and Egypt to assess the potential mobilization of these potentially toxic metals. The German soils were classified as Eutric Fluvisols, Tidalic Fluvisols, Haplic Gleysols, and Calcic Luvisols, and the Egyptian soils as Eutric Fluvisols, Sodic Fluvisols, and Haplic Calcisols. The geochemical fractions (acid soluble (F1), reducible (F2), oxidizable (F3), and residual (F4) fraction) of the metals were sequentially extracted using the sequential extraction technique of the Commission of the European Communities Bureau of Reference (BCR). The maximal total concentrations (mg kg − 1 ) of Cu (3242), Ni (105), and Zn (1672) were in the German Eutric Fluvisols, while the maximal concentrations of Co (37) were in the Egyptian Eutric Fluvisols, and those values exceeded the international maximum allowable soil concentrations. The values of enrichment and contamination factors exhibit a clear indication of dramatic contamination by Cu and Zn at the Eutric Fluvisols along the Wupper River, Germany. The acid soluble fraction of all metals (except for Ni in the Calcic Luvisols) was higher in the German soils than the Egyptian soils. The reducible fraction of Co, Cu, Ni, and Zn was the dominant non-residual fraction (as precentages of total) in all Egyptian soils and in the German Eutric Fluvisols as well as for Zn in the Tidalic Fluvisol and Co in the Calcic Luvisols. The potential mobile fraction (PMF = ∑ F1 − F3) of Co, Cu, Ni, and Zn accounted (% of total) for 39–61, 15–60, 21–57, and 6–44, respectively in the Egyptian soils, while it accounted for 14–70, 11–92, 2–73, and 8–89, respectively in the German soils. The high PMF of the metals in the German Eutric Fluvisols, Haplic Gleysols, and Sodic Fluvisols might reflect that the sources of these metals are of anthropogenic origin here. However, the dominance of the metals residual fraction in the Egyptian soils supports the assumption of the geogenic origin of these metals in these soils. The canonical discriminant analysis as a multivariate statistical procedure was applied and differentiated the soils according to their geochemical behavior into four clusters i.e., 1) Eutric Fluvisols, Calcic Luvisols, and Haplic Calcisols; 2) Egyptian Fluvisols (Eutric and Sodic); 3) Haplic Calcisols; and 4) Tidalic Fluvisols. In conclusion, the potential risk of the metals in the anthropogenic polluted soils is higher than in the soils naturally enriched with these metals. Therefore, remediation approaches may be needed in the German Eutric Fluvisols, Haplic Gleysols, and Sodic Fluvisols.

Assessment of the physical quality of a Fluvisol in the Brazilian semiarid region
Geoderma Regional, 2017Co-Authors: Rodolfo Marcondes Silva Souza, Eduardo Soares De Souza, André Maciel Netto, André Quintão De Almeida, Genival Barros Júnior, José Raliuson Inácio Silva, José Romualdo De Sousa Lima, Antonio Celso Dantas AntoninoAbstract:In Brazil, the physical quality of soils has been frequently investigated using the S index (idS); however, information regarding the quality of other important agricultural soils such as Fluvisols is lacking. Therefore, this study aimed to evaluate the soil physical and hydraulic interaction with idS and determine how these properties are distributed spatially in a Fluvisol from Parnamirim, located in the semiarid region of Pernambuco. Soil water retention θ(h) and hydraulic conductivity K(θ) curves were generated using 30 samples from the soil surface by using the Beerkan method. The parameter θ(h) was used to determine the idS for each sample; subsequently, Pearson's correlation and geostatistic analyses were conducted to determine the properties that were significantly correlated with idS. The idS showed an average value below that considered as reference for soils with good physical quality and had significant correlation only with available water (θavbl), owing to the presence of meso- and micropores and clay, sand, and coarse sand contents. Thus, the soil physical quality measure S index alone was not sufficient to evaluate accurately the physical quality of the Fluvisol.

fungal biodiversity and metabolic potential of selected Fluvisols from the vistula river valley in lubelskie poland
Applied Soil Ecology, 2021Co-Authors: Karolina Furtak, Jaroslaw Grządziel, Anna Galązka, Karolina Gawryjolek, Jacek NiedźwieckiAbstract:Abstract Analyses of the soil mycobiome, though limited, are needed to understand interactions in the ecosystem. We have attempted to assess structural and functional differentiation of fluvisol mycobiomes located in the Natura 2000 area in Vistula River valet in Lubelskie, Poland. The metabolic potential of mycobiomes was analysed using Biolog® FF Plates™, structural differentiation was determined using next-generation sequencing (NGS) and the glomalin content in selected soils was determined. The obtained results showed differences between mycobiomes of the examined Fluvisols. Ascomycota and Basidiomycota were identified as the dominant phyla. In addition, 51 genera common to the examined Fluvisols were identified. The highest content of glomalins and nutrients (organic and total carbon, organic matter) was recorded in sample F1 – medium Fluvisols, while metabolic activity and structural differentiation were highest in sample F3 – very light Fluvisols. The very light Fluvisols (F3), with the smallest nutrient reserves, are characterised by the greatest fungal biodiversity. These results suggest that a greater variety of fungi and their synergistic effects can ensure the survival of the entire mycobiome in a less fertile soil environment.

prevalence of unclassified bacteria in the soil bacterial community from floodplain meadows Fluvisols under simulated flood conditions revealed by a metataxonomic approachss
Catena, 2020Co-Authors: Karolina Furtak, Jaroslaw Grządziel, Anna Galązka, Jacek NiedźwieckiAbstract:Abstract Extreme hydrological events cause stress in a soil environment, which directly affects the activity of the soil microbiome. The objective of this research is to determine the functional and structural biodiversity changes of soil bacteria in three different Fluvisols from river floodplains under the condition of simulated floods. The nine soil sods (three for each fluvisol), with living vegetation, were collected in August 2018, and fitted into a separate transparent, polypropylene container. At the same time, water was taken from the Vistula River. The sods were flooded with water from the river to a level of 5 cm above the soil. The mesocosm experiment was conducted over 14 days under controlled conditions. During the experiment, the pH values, dehydrogenase activity, metabolic potential on EcoPlate™ and structure of the soil bacterial community by next generation sequencing (NGS) were analysed. The results obtained show that simulated flooding affects soil pH, dehydrogenase activity as well as metabolic potential and structural diversity of soil bacteria communities. The proportions of individual bacteria change, and new species appear in the soil, both those introduced by the water and woken up from inactive forms, while some groups of microorganisms die out. It can be unequivocally stated that extreme conditions caused by simulated flooding have a significant impact on soil microorganisms.

analysis of soil properties bacterial community composition and metabolic diversity in Fluvisols of a floodplain area
Sustainability, 2019Co-Authors: Karolina Furtak, Jaroslaw Grządziel, Anna Galązka, Jacek NiedźwieckiAbstract:The quality of a soil environment affects the microbial community that inhabits it. We decided to examine whether soils formed from river sediments, located in an area of high biodiversity of organisms, are fertile and microbiologically diverse. Fluvisols are considered to be one of the most fertile soils. In this research, bacterial and metabolic diversity, as well as physico–chemical parameters, in three Fluvisols from the Vistula River Gorge of Lesser Poland was investigated. The analysis of physico–chemical and biological parameters demonstrated statistically significant differences between the three Fluvisols examined. While determining the metabolic potential of soil microbiomes with the use of the EcoPlate™ Biolog® technique, we also noted variation between the Fluvisols; however, they were arranged in a significantly different manner from other properties. The next generation sequencing method enabled us to determine the microorganisms common to three Fluvisols, and we identified bacteria specific to individual soils. These results corresponded with the data obtained through EcoPlate™, indicating that the structural diversity and metabolic potential of the microbiome does not always depend on soil quality parameters. Meanwhile, the increased structural diversity of the microbiome was found to improve the metabolic potential of soil microorganisms.
