Summary: A new method for producing nanosilver using lignosulfonic acid derivative and developing a chemically modified GCE/AgNPs-LS/Hg electrode material is presented in this research. The modified electrode shows enhanced performance in detecting Tl+ ions compared to unmodified electrode. The novel AgNPs-LS/Hg2+ complex is assumed to be suitable for preparing functionalized nanostructured material and can serve as an electrochemical sensing platform for heavy metals.

Summary: The optimal working parameters of the innovative electrode GCE/AgNPs-D3 were determined and their selectivity was assessed. The stripping anodic peak current of thallium exhibited linearity in the range from 4.9 × 10(-8) to 4.9 × 10(-7) mol·dm(-3), with a limit of detection (LOD) of 7.16 ppb (3.5 × 10(-8) mol·dm(-3)). Furthermore, the new electrode showed a more than sevenfold improvement in the thallium current signal compared to the unmodified electrode GCE. High selectivity was achieved using EDTA disodium salt as a complexing agent for other metals.

Summary: This study presents a reagentless sample preparation method for the detection of particulate Pb contaminants in tap water using membrane electrolysis. The membrane electrolysis allows for the in-situ generation of nitric acid, which, when combined with anodic stripping voltammetry, provides a powerful and reagent-free detection of Pb2+. The setup configuration enables semi-autonomous operation and requires minimal attention, making it more suitable for continuous measurements of particulate contaminants in tap water.

Summary: In this paper, a graphdiyne (GDY)-modified glassy carbon electrode was prepared and used for the sensitive and simultaneous detection of Zn2+, Cd2+ and Hg2+ heavy metal ions. The GDY-modified electrode provided a larger surface area and more active sites for the absorption of metal ions. By codeposition with Bi3+, the heavy metal ions were pre-concentrated on the GDY-modified electrode surface, resulting in high sensitivity and selectivity during stripping analysis. The detection ranges and limits for Zn2+, Cd2+ and Hg2+ were determined using differential pulse anodic stripping voltammetry.

Summary: In this work, a new electrochemical Hg2+ sensing platform based on porous activated carbon (BC/Cu2O) modified with cuprous oxide was developed. Differential pulse anodic stripping voltammetry (DPASV) was used to investigate the sensing capability of the BC/Cu2O electrode towards Hg2+. The BC/Cu2O electrode exhibited excellent electrochemical activity due to the excellent conductivity and large specific surface area of BC, and the excellent catalytic activity of Cu2O nanoparticles. The sensor showed high sensitivity with a low detection limit of 0.3 ng/L and a wide linear response range from 1.0 ng/L to 1.0 mg/L, as well as good accuracy, acceptable precision, and reproducibility.

Summary: This study reports on the electroanalytical performance of a glassy carbon electrode (GCE) modified with antimony and bismuth (Sb/Bi-GCE) for detecting heavy metal ions, using lead and cadmium as model analytes. The Sb/Bi-GCE showed superior performance compared to Bi-GCE and Sb-GCE surfaces. For instance, the limit of detection for lead was 0.01 ppb using Sb/Bi-GCE, while it was 0.1 ppb on Bi-GCE and 1 ppb on Sb-GCE.

Summary: The study found that micritic limestones from the Greater Karatau area can preserve Nd isotope signatures of seawater. The Nd isotope composition of seawater in the Karatau platform indicates the final closure of the Uralian-Turkestan Ocean, and reveals that subduction along Kazakhstan's active margin began at least 23 million years earlier than previously thought.

Summary: Sewage sludge from municipal wastewater treatment plants is a serious environmental problem due to its varying heavy metal content, and it has been challenging to measure the thallium content. This study estimated the contamination level of thallium in sewage sludge from a Polish treatment plant and found that approximately 13% of the thallium could gradually be released into the environment.

Summary: This study documents the deterioration of groundwater chemistry in the recharge zone of Tursko well-field in Poland due to high nitrate concentrations and pharmaceutical compounds. The infiltration of treated wastewater and drainage water into groundwater is shown to activate denitrification, resulting in decreased nitrate concentrations but increased concentrations of denitrification products. The ability of pharmaceutical compounds to act as anthropogenic tracers indicates that wastewater infiltration is a significant factor influencing the quality of drinking groundwater.
