Rapid assessment of soil and contaminant variability via portable x-ray fluorescence spectroscopy: Copşa Mică, Romania

Development of a hybrid proximal sensing method for rapid identification of petroleum contaminated soils

“…PXRF can quantify elements from z = 15 (P) through 94 (Pu) and is useful for environmental monitoring of many elements in soils and other geological materials (Weindorf et al, 2013a;Wiedenbeck, 2013). Applied to soil science, many studies have focused on metal contamination assessment using PXRF (Weindorf et al, , 2013bParsons et al, 2013;Paulette et al, 2015;Hu et al, 2014), and PXRF elemental data has been used as a proxy for a wide number of soil parameters such as pH (Sharma et al, 2014a), cation exchange capacity (Sharma et al, 2014b), soil calcium and gypsum (Weindorf et al, , 2013aZhu and Weindorf, 2009), soil texture (Zhu et al, 2011), soil salinity (Swanhart et al, in press), and soil horizonation (Weindorf et al, 2012b,c).…”

Assessment of the Quality of Polluted Areas in Northwest Romania Based on the Content of Elements in Different Organs of Grapevine (Vitis vinifera L.)

“…These high concentrations can be attributed to the pollution factor (in Baia Mare and Baia Sprie areas) or the extensive usage of Cu-based plant protection products (in the Simleul Silvaniei area). Detected values were higher than those reported previously from this area (640.6 mg/kg) [17], (599.75 mg/kg) [18], (314.00 mg/kg) [16] or other wine-producing areas in Southeast Romania [19], but were within the range established for Cops , a Mică (77-7675 mg/kg) [3].

“…High purity ICP Multi-element Standard Solution XXI CertiPUR obtained from Merck (Darmstadt, Germany) was used for the calibration curve in the quantitative analysis. HNO 3 istical Analysis rage and standard deviation were calculated, and data were interpreted with the analysis ce (ANOVA) and the average separation was performed with the Duncan test at p ≤ 0.005. correlation coefficient was calculated using SPSS Version 24 (SPSS Inc., Chicago, IL, USA), 6 (Microsoft, New York, NY, USA) and Addinsoft version 15.5.03.3707 (Microsoft, New , USA. Value higher than 0.5 indicate a strong correlation between analyzed varieties, a correlation between two parameters shows that both parameters increased, and a negative n indicates that a parameter increased while the second one decreased and vice-versa.…”

Influence of Particle Size in the Characterization of Street Dust by Proximal Soil Sensing

“…A specific type of proximal soil sensor, portable X-ray fluorescence (XRF) devices, use a spectrometric technique that measure, compare and contrast the energy emitted by the elements in the sample after excitation by a source of X-rays in order to quantify the relative concentrations of the elements [4,6,7]. Portable XRF devices have been used in the analysis of soil, sediments and road dust, either as the main analytical technique or as part of a compound method [8][9][10][11].…”
