“…Peh and Miko [36] measured average V concentrations of 70 mg kg −1 in Croatia, which is in line with the values reported here. Ivanov and Kashin[37] recorded (AAS-measurement after aqua regia destruction) average V concentrations of 110 mg kg −1 in alluvial deposits in Transbaikalia (Russia), and Wigginton and Price[38] found (ICP-OES determination after aqua regia destruction) concentrations between 8 and 17 mg kg −1 in floodplain soils of Bayou Creek (UK). On the 4th October 2010, red mud suspension were released from the Ajkai Timfoldgyar Zrt alumina plant.…”

Vanadium (V) is a naturally occurring trace element, but total concentrations in soils and sediments are also dependent on the parent material and might be influenced by anthropogenic activities (e.g., steel industry). Despite the fact that threshold values for V in soils and/or sediments exist in various European countries, in Belgium, V is not taken into account when the environmental quality of soils and sediments has to be evaluated, despite the existence of several (diffuse) sources for V. In the first part of the study, the occurrence of V alluvial soils in Belgium was compared with V concentrations in alluvial soils (floodplain soils) across Europe. By analysis of both the Belgian and European data, the relationship between physicochemical soil characteristics and total V concentrations was quantified and some areas polluted with V were detected. A regression equation, in which V concentrations in alluvial soils were expressed as a function of major element composition, was proposed for the Belgian and European data. Additionally, single extractions with CaCl2(0.01 mol L-1) and ammonium-EDTA (0.05 mol L-1) were used to estimate short- and long-term mobility of V in the alluvial soils.

“…The correlation coefficient of vanadium was calculated with some major, minor, trace elements, and some soil properties, (Table 9). Vanadium showed a positive correlation with Al2O3, it may be due to accompanying in bauxite mineral (Ruyters et al, 2011), and attributed to direct adsorption on clay minerals (Ivanov and Kashin, 2010), or indirect by the negative charge reflection mechanism of the clay minerals surfaces, so Al +3 ions can adsorb to the surfaces of clay minerals, and change their charge to positive and lead to the adsorption of vanadium, potassium ions also act by the same mechanism and this is observed through the positive correlation with K2O (Huang and Yang, 2020). Vanadium showed a positive correlation with MgO with a value of r = 0.91 which may be due to their geochemistry accompanying in clay minerals and silicate minerals, or for the similarity of their sources as a result of weathering dolomite rocks containing about 30-120 mg/kg of magnesium (Gransee and Führs, 2013;Mayland and Wilkinson, 1989).…”

“…Sometimes its concentration in the fine grains may exceed those found in the parent rocks (Kabata-Pendias and Pendias, 1985). In general, it is usually associated with the clay fraction and clay minerals of the soil and its abundance increases with increase of these minerals in the soil (Breit andWanty, 1991 andIvanov andKashin, 2010), and ion exchange and/or adsorption on these minerals represent the major mechanism of its accumulation in the soil (Ghani et al, 2012). Soil colloids, such as metal oxides, organic matter and clay minerals, are characterized by the presence of two types of charge, a permanent charge that is not affected by the pH, and a variable charge that depends on the pH, when the pH is greater than 7, soil has a negative net charge, and at lower values (pH <7) its net charge is positive (Karak et al, 2005 andSherene, 2010).…”

The vanadium geochemistry was estimated in the topsoil of Kirkuk, northern Iraq, and its potential sources are forecasted by using multivariate statistical analysis as useful tools in this field, in addition to assessing soil pollution with vanadium by using individual indices such as enrichment factor, geo-accumulation index (Igeo) and contamination factor (CF). Eighteen topsoil samples were collected with a depth ranges 0–20cm, and analyzed by using the inductively coupled plasma-mass spectrometer technique (ICP-MS). The results showed that the concentration of vanadium ranged from 37-51 mg/kg, with an average of 46 mg/kg, relatively it was high concentrations in the agricultural and residential areas compared to the industrial areas. Statistical analysis indicated the contribution of oil combustion and the use of phosphate fertilizers in increasing vanadium concentrations in topsoil. Pollution indices of enrichment factor were in the minimal enrichment category for all samples, geo accumulation index was non-contamination categories for all samples, while Contamination factor was low for all samples.

“…Supply Chain Strategies (SCS) are the strategic frameworks conceptualized in supply chain strategy by [8] and encompass four key components: 1) supply chain goals, 2) supply chain design, 3) supply chain planning, and 4) supply chain operations. It is crucial for organizational supply chain strategies to aim for simplification.…”

“…These measures assist decision-makers in managing threats and risks, thereby ensuring the long-term resilience of the organization [12]. Supply Chain Design (SCD) is a process in the supply chain strategies framework (Ivanov, 2010) and helps to create a competitive advantage [13]. SCD influences organizational performance and manages short-term and long-term plans.…”

In business operations conducted under uncertain circumstances, issues such as escalating transportation costs, pervasive uncertainty, and a lack of collaboration among enterprises have surfaced, constraining opportunities for business expansion. Consequently, companies are compelled to adapt swiftly to sustain their operations. This research investigates the Factors Influencing the Supply Chain Resilience of Businesses amid Uncertain Circumstances. A comprehensive analysis of the pertinent literature has been undertaken, employing various methodologies to shed light on the principal challenges and drivers confronting supply chain management. The findings derived from the literature review underscore the pivotal significance of supply chain strategy and design in shaping the resilience of supply chains, particularly in contexts characterized by uncertainty. Consequently, the analysis of strategic aspects, the formulation of resilient supply chain designs, and investments in resilience are found to exert a substantial and positive influence on anticipated business outcomes. These proactive measures serve as a robust safeguard against disruptions, ensuring the sustained continuity of business operations even during times of crisis.
