“…Phytoavailability of Pb is pH-dependent. By lowering soil pH, the availability of Pb could increase (Gul et al 2020).We could conclude that other original properties of shooting range soil do not drastically change the solubility of contaminants (heavy metals) because the main soil properties discussed earlier did not change signi cantly, except pH (Ashworth and Alloway 2008; Lewińska and Karczewska 2019).…”

“…Research has shown the presence of elevated concentrations of Pb in ora growing in nearby shooting ranges (Fayiga and Saha 2016). Due to extreme Pb concentrations of in soil, seed germination, the uptake of nutrient (Na, Ca, K, P, Mg, Zn, Fe, Cu), chlorophyll content, plant growth, biomass decreased (Hadi and Aziz 2015;Gul et al 2020). Some heavy metals are essential for plant growth, but at high concentrations, they become toxic (e.g., Co, Cu, Fe, Mn, Zn), while others (e.g., Cd, Pb, Hg) are toxic even at low concentrations because they have no known physiological functions in plants (Boquete et al 2021).…”

Shooting range soil contamination with heavy metals is a common problem around the world. Usually, lead is the primary contaminant in the shooting ranges. Extreme concentrations of trace elements create a toxic living environment for various plants. The purpose of this study was to evaluate the effect on lettuce (Lactuca sativa L.) grown in contaminated shooting range soil. The results showed that physiological parameters root elongation, shoot length and fresh biomass per plant were negatively affected, especially in the most contaminated site in the shooting range. At the most contaminated shooting range site shoots accumulated higher concentrations of Ni and Zn, roots – Cu, Ni, and Zn. The roots of plants grown in the most contaminated soil accumulated significantly higher concentrations of Cu, Ni, and Sb than the reference and accumulation of Cu, Fe, Mn, Ni, Sb and Zn in the roots of the plants grown in the most contaminated site was higher compared to shoots. Bioaccumulation factor of Cu and Ni in plants from the most contaminated site was significantly higher than the reference. Metals absorbed by L. sativa were accumulated in root and lower metal translocation in shoots was determined, except for Mn.

“…Accordingly, the detection method of coupling SWASV with SVR, which required lower cost and simpler electrode modification, could accurately detect the Pb(II) concentration under the interference of Cu(II). 1 GC/GQDs-NF/GCE: Graphene quantum dots-nafion modified glassy carbon electrode; 2 (BiO) 2 CO 3 @SWCNT-Nafion/GCE: (BiO) 2 CO 3 @single-walled carbon nanotube nanocomposite/nafion composition modified glassy carbon electrode; 3 : SWCNTs-Nafion/IL/SPE: Bi/single-walled carbon nanotubes-nafion/ionic liquid nanocomposite modified screen-printed electrode; 4 Bi/SPE: Bismuth film modified screen-printed carbon electrode; 5 Bi/p-Tyr/GC: rod-like poly-tyrosine/Bi modified glassy carbon electrode; 6 Bi 2 O 3 /GCE: Bismuth oxide modified glassy carbon electrode; 7 Bi-film/GCE: Bismuth film modified glassy carbon electrode.…”

“…A large amount of lead ions have accumulated in soil in recent decades due to improper agricultural management, such as excessive usage of fertilizers, pesticides and sewage water irrigation [1], and the addition of wine vinasse [2,3]. Lead, as one of the most toxic heavy metals (HMs), can cause acute and chronic damage to the eco-environment even at low concentrations and harm human health because of its spreadable accumulation through food chains [4,5]. Therefore, developing a high-efficiency and fast method for accurate detection of lead in soil is of great necessity.…”

In this study, an effective method for accurately detecting Pb(II) concentration was developed by coupling square wave anodic stripping voltammetry (SWASV) with support vector regression (SVR) based on a bismuth-film modified electrode. The interference of different Cu2+ contents on the SWASV signals of Pb2+ was investigated, and a nonlinear relationship between Pb2+ concentration and the peak currents of Pb2+ and Cu2+ was determined. Thus, an SVR model with two inputs (i.e., peak currents of Pb2+ and Cu2+) and one output (i.e., Pb2+ concentration) was trained to quantify the above nonlinear relationship. The SWASV measurement conditions and the SVR parameters were optimized. In addition, the SVR mode, multiple linear regression model, and direct calibration mode were compared to verify the detection performance by using the determination coefficient (R2) and root-mean-square error (RMSE). Results showed that the SVR model with R2 and RMSE of the test dataset of 0.9942 and 1.1204 μg/L, respectively, had better detection accuracy than other models. Lastly, real soil samples were applied to validate the practicality and accuracy of the developed method for the detection of Pb2+ with approximately equal detection results to the atomic absorption spectroscopy method and a satisfactory average recovery rate of 98.70%. This paper provided a new method for accurately detecting the concentration of heavy metals (HMs) under the interference of non-target HMs for environmental monitoring.

At the most contaminated shooting range site shoots accumulated higher concentrations of Ni and Zn, roots – Cu, Ni, and Zn. The roots of plants grown in the most contaminated soil accumulated significantly higher concentrations of Cu, Ni and Sb in comparison with control (p < 0.05). Accumulation of Cu, Fe, Mn, Ni, Sb and Zn in the roots of the plants grown in the most contaminated site was higher compared to shoots (p < 0.05). Bioaccumulation factor of lettuce was lower than 1, only BF of Cu and Ni in plants from most contaminated site was significantly higher compared to control. In terms of translocation factor, the TFsoil to root of Cu and Pb among all plants and Ni in plants grown in the most contaminated site above 1 shows that metals absorbed by L.sativa were accumulated in root and lower metal translocation in shoots was determined, except for Mn.
