“…The Ps-LIPS technique requires a solid sample with a flat and smooth surface to generate a stable and reproducible laser-induced plasma (Shaheen et al 2021). The obtained homogenized powders were prepared for analysis by Ps-LIPS technique by pressing into pellets of 1 cm diameter and about 3 to 4 mm thickness using a hydraulic at a pressure of 5 Ton.…”

Excess fertilizer and chemical use have contaminated soil with harmful heavy metals near the Abu-Zaabal facility in Egypt. This study pioneers an approach using picosecond laser-induced plasma spectroscopy (Ps-LIPS) and inductively coupled plasma optical emission spectrometry (ICP-OES) to quantify toxic metal levels without calibration constraints. A 100 mJ Nd: YAG laser with 170 picosecond pulses has been employed for the Ps-LIPS. Systematic soil sampling at six sites near the facility enabled Ps-LIPS to formulate unrestricted calibration-free curves for lead, cadmium, cobalt, zinc, iron, and nickel. Applying the Boltzmann distribution and plot methods anchored to calcium spectral lines determined plasma electron density and temperature under local thermodynamic equilibrium. Models were validated against ICP-OES, affirming Ps-LIPS with under 8% average relative error. Results revealed notable concentration variations contingent on the metal, sampling site, and orientation to the facility. This pioneering Ps-LIPS study demonstrates precise quantification of toxic metals in soils without prior calibration. It provides a pragmatic tool for contamination assessment, representing a seminal advance in environmental analytical methodology.

“…Contamination of agricultural soil with potentially toxic elements (PTEs) has been reported from many parts of the world and poses a risk to both human and animal health [1][2][3][4][5]. Due to their ability to bind to a variety of substances, soil particles can be thought of as a significant sink for pollutants that may come from a variety of anthropogenic and natural sources [5][6][7][8]. In the last few decades, growing populations and our evolving way of life Minerals 2024, 14, 576 2 of 22 have led to increased food consumption, placing an immense strain on soil resources [9][10][11].…”

“…In the last few decades, growing populations and our evolving way of life Minerals 2024, 14, 576 2 of 22 have led to increased food consumption, placing an immense strain on soil resources [9][10][11]. For instance, to ensure global food security by 2050, food production must rise by up to 70% [7,12]. To meet this demand, agricultural practices have become more intensive, leading to increased use of pesticides, fertilizers, and other chemicals [13][14][15][16].…”

Soil contamination with potentially toxic elements (PTEs) in the Malwa region belt of Punjab, India, can be a serious concern as a result of intensive agricultural practices and overuse of agrochemicals. The main objectives of the present study were to evaluate the spatial distribution, geochemical signature, and contamination level/health risk of PTEs in 76 soil samples (0–10 cm) collected from the three districts viz. Muktar, Faridkot, and Moga of Punjab, India. The result shows that PTEs concentrations vary widely in the region, with Fe and Mn distribution patterns being mostly coherent with each other. When compared to the Indian natural soil background values, the average concentration of Pb and Zn were higher than the limit, only Pb exceeded the average values of the world background and upper continental crust (UCC). Spatial autocorrelation plotted with a local indicator of spatial association (LISA) in GeoDa software version 1.18 was used to identify hotspots. A positive spatial autocorrelation (>0.2) was indicated with Moran’s I values for Pb, V, Mn, Cu, and Cr, being highest for Pb. A principal component analysis (PCA) identified the major geo-chemical patterns of Fe-Al-V-Cr and TOC-Mn-Zn-HCO3−, which were positively loaded on PC1. This indicates that Fe/Al-oxyhydroxides and organic matter play a dominant role in controlling metal mobility in soils. This can be further substantiated with the Spearman’s rank correlation values. The contamination factor indicates that only Pb and Zn (15.7% and 3.9% samples, respectively) were under high risk. This could be due to the excessive application of chemical fertilizers. The large range of Cdeg values suggests that there are variations in the degree of soil pollution due to PTEs. A little over 3.9% of samples had significant contamination, compared to 72.3% of samples with low contamination and 23.6% of samples with moderate contamination. Human non-carcinogenic and carcinogenic risk levels were investigated. The HI values for adult ranged from 0.00 to 0.2, and values for children ranged from 0.009 to 1.2. These findings suggest that both children and adults are not at potential risk, except in a few locations. Overall, the results of this study provide the current baseline status of toxic elements in agricultural soil. This would be helpful for developing strategies for sustainable management of the soil resources in the region, as well as for future monitoring programs of the soil quality in the Malwa region as a whole, to track any changes in the contamination levels over time.

“…4 In recent years, great efforts have been made to develop efficient heavy metal detection techniques to prevent the increase of heavy metal concentrations, such as ultraviolet spectrophotometry, 5 atomic absorption spectrometry, 6 fluorescence spectrometry, 7 inductively coupled plasma, 8 atomic fluorescence spectrometry, 9 and inductively coupled plasma mass spectrometry. 10 Among them, fluorescence spectrometry is one of the most economical and promising strategies for detecting heavy metals. 11 The advantage of fluorescent spectrometry is non-destructive testing, and which can directly analyze finished products.…”
