“…Although techniques like atomic absorption or ICP are especially powerful in the analysis of metals [5,6], they should be complemented by portable, low-cost techniques for these applications where simplicity, ease of use, economy and possibility of measuring on-line or in-situ are required. Among these techniques, voltammetry is a sensitive, cheap and versatile choice, especially when it includes analyte preconcentration by reduction (anodic stripping voltammetry, ASV) or by adsorption (adsorptive stripping voltammetry, AdSV) [7].…”

Abstract:The influence of the experimental conditions (glutathione concentration and incubation time and temperature) concerning the covalent immobilization of glutathione via carbodiimide coupling on the behavior of a glutathione modified screen-printed carbon electrode obtained by electrografting is evaluated. The optimized parameters fasten the modification process and improve the performance of the sensor as compared to the usual procedure. This suggests the convenience of a tailored preparation of metal sensors based on metal-binding biomolecules such as glutathione.

“…Nowadays, many analytical methods are employed for soil analysis, 2 and inductively coupled plasma atomic emission spectrometry (ICP-AES) is most widely used. To extract elements from soil into solution, sample digestion in different acid mixtures composed of HF, HCl, HNO3, HClO4, and H2O2 is applied.…”

The possibility of direct analysis of soils by two-jet plasma atomic emission spectrometry was investigated using certified reference materials of black earth, grey desert and red soils. It was shown that As, B, Cd, Cu, Hg, P, and V could be determined after a 2-fold, and Be, Co, Cr, Ga, Nb, Pb, and Zn-after a 10-fold dilution of the samples by a spectroscopic buffer using calibration samples based on graphite powder. The strongest matrix effects were revealed for red soil having the highest Al and Fe concentration, which led to the overstated concentrations of some elements. The overstating factor depended on analyte concentration and was no more than 2. A clear advantage of the suggested technique over existing methods is the simple sample preparation process, which requires no reagents except a spectroscopic buffer, and possibility of using the same calibration samples for analysis of different soils.

“…The presence of toxic elements in soil is often the result of emissions caused by fuel combustion, industrial activities, and the utilization of agrochemicals such as fertilizers and pesticides (Soodan et al 2014). However, in order to provide nutrients in adequate amounts and to ensure successful harvests, the use of agrochemicals is essential in some cases; consequently, the long-term application of metal-containing agrochemicals can be potentially damaging (Kelepertzis 2014).…”

“…Several methods have been proposed for elemental determination in soil and sediments samples using different analytical techniques, among others atomic fluorescence (AFS), X-ray fluorescence spectrometry (XRF), neutron activation analysis (NAA), atomic absorption spectrometry (AAS), inductively coupled plasma optical emission spectrometry (ICP OES), or inductively coupled plasma mass spectrometry (ICP-MS) (Soodan et al 2014;Roje 2011;Melaku et al 2005). However, ICP-MS is one of the most widely used, apart from its multi-elemental capability this technique offers a high sensitivity, wide dynamic range, isotope ratio information, and the possibility of sample introduction using alternative devices such as electrothermal vaporization (ETV) and laser ablation (LA) (Krishna et al 2012).…”

The concentration of metals in Brazilian soil under no-tillage (NT) and an area under native vegetation (NV) was determined by inductively coupled plasma mass spectrometry. The applied method was based on microwave-assisted acid digestion using HNO3, HCl, H2O2, and HF. The accuracy of the method was evaluated by analyzing two certified reference materials (BCR-142 and RS-3). The relative standard deviation for all target elements was below 8% indicating an adequate precision and the limit of detection ranged from 0.03 μg g(-1) (Cd) to 24.0 μg g(-1) (Fe). The concentrations of Al, As, Ba, Cd, Cu, Fe, Mg, Mn, Ni, Pb, Sr, and Zn in the different layers (0-10, 10-20, 20-40, and 40-60 cm) were determined in two types of soils, located in Paraná State in Brazil. The soil layers analysis revealed a different behavior of metals concentrations in soil samples under NT and NV. The obtained results showed a clear impact of anthropogenic action with respect to specific metals due to many years of uncontrolled application rates of limestone and phosphate fertilizers.
