Summary: The study found that secondary minerals could effectively remove toxic elements such as arsenic and thallium. In environments polluted by mining, these elements were abundant and a large percentage of total arsenic and thallium could be mobilized easily into the environment. Furthermore, new thallium arsenate phases were identified, highlighting the need for further research on thallium speciation in extremely arsenic- and thallium-rich environments.

Summary: The use of Al beverage can powder as a substitute for zero-valent Al to conduct the Fenton-like reaction for Tl(I) oxidation and subsequent precipitation of Tl(III) at pH 9.5 was effective for Tl remediation. While the addition of Fe(III) or Fe(II) facilitated Tl(I) oxidation, it also reduced the overall Tl removal efficiency, highlighting the importance of considering the trade-off between oxidation and removal. This study demonstrated the comparable Tl(I) removal efficiency of AlCP to state-of-the-art (nano)composites, offering a unique opportunity for balancing hazard remediation and waste reduction/reuse considerations.

Summary: Dried blood spot (DBS) detection is a convenient and reliable method for large-scale evaluation of arsenic exposure in human population. A Lego-spinner pretreatment device is designed for speciation analysis of arsenic in DBSs by IC-ICP-MS. The device can extract and separate arsenic species from the blood matrix efficiently, and the concentrations of arsenic species in the DBS are highly correlated with those in whole blood. The DBS sampling approach can effectively preserve arsenic species for at least 30 days, and the contents of arsenic species in DBSs prepared from capillary blood are in agreement with venous whole blood.

Summary: This study investigated the performance and mechanisms of sulfidized zero-valent manganese (SZVMn) for removing thallium (Tl) from wastewater. The results showed that liquid nitrogen modified SZVMn (LSZVMn) had more interior channels and pores than SZVMn, leading to improved adsorption of Tl(I). LSZVMn demonstrated effectiveness and robustness in Tl(I) removal in the presence of co-existing ions up to 0.1 M. The mechanism of Tl(I) removal with SZVMn involved sulfidation-induced precipitation, manganese reduction, surface complexation, and electrostatic attraction.

Summary: In this study, EQCM was used to monitor histidine adsorption and palladium ions complexation on an amalgam-modified gold QCM substrate. The results showed that histidine adsorption on the electrode is potential-dependent, and stronger bonds are formed between histidine and palladium compared to histidine and mercury. By applying a specific potential, histidine-palladium complex can be adsorbed on the mercury surface for Pd determination using AdSV.

Summary: The stripping voltammetry at HMDE is proposed for Cd and Pb determination in high salinity natural brines. The proposed method allows for the determination of Cd and Pb at very low concentrations with minimal dilution. The use of thermal chloride stripping or isolation by Chelex 100 improves the quality of the obtained data. The LOQ values are below the recommendations for the use of brines in balneology.

Summary: Reduction of Tl(iii) and oxidation of As(iii) occur immediately after sampling, making it necessary to separate the inorganic Tl and As species for reliable results in water speciation analysis. This study presents a simple and fast sample pretreatment method using ion exchange cartridges, allowing for on-site separation of Tl and As species. The separated species are quantified using ICP-MS in the effluent. Direct determination is particularly important for trace amounts of these species in seawater near harbors.

Summary: The corrosion of installations carrying high salinity water, especially natural brine, is a significant concern. Analyzing the presence of iron and chromium in such complex systems is challenging but can be achieved through UV-Vis spectrophotometry after dilution and liquid-liquid extraction or thermal chloride stripping. The study reveals that during the corrosion process, chromium is less easily released to the solution compared to iron. The short-term contact of stainless steel with natural brine results in insignificant amounts of iron and chromium being released, impacting the therapeutic value only minimally.
