This study aimed to investigate the levels of contamination of potentially toxic trace elements in the soil of Dong Nai Province, Vietnam. To achieve this, the Instrument Neutron Activation Analysis (INAA) method was employed to measure the concentrations of five potentially toxic trace elements, including manganese (Mn), arsenic (As), chromium (Cr), antimony (Sb), and zinc (Zn), across 30 soil samples collected from the region.

Ebook "Bismuth-mediated organic reactions (Topics in current chemistry, Volume 311)" deals with only one element of the periodic table but still contains a large amount of new knowledge, all of which comes from a single element: bismuth! The history of bismuth in synthetic chemistry is relatively short. The most important features of this element, arising from its low toxicity and high reactivity, were first highlighted only recently.

Halide perovskites are now considered promising materials in the field of optoelectronic devices. Recently, the double halide-perovskite cesium tellurium iodine Cs2TeI6 has shown its potential application due to its strong stability, high absorption coefficient, suitable bandgap and composition of non-toxic elements.

Graphene is a promising candidate for CO2 capture, storage, and sensor. Doping graphene with other elements is an effective way to modify its CO2 storage ability. The literature has shown that the N and B dopants could change the adsorption strength of CO2 on the graphene substrate.

The results showed that SOM content was higher in horizon A, whereas mineral matrix elements Al, Fe, and Mg contents were higher in horizon B. Ca and P contents gradually decreased with soil depth due to the influence of fertilizer. Three types of trace element concentration profiles were identified: (1) decrease with depth for Cd and Hg

The results of Monte Carlo simulation were generally in accordance with the detected contamination and risk levels, except for several elements (Cu and Zn) with huge spatial heterogeneity. According to the Monte Carlo simulation, the river sediments could undergo extremely high contamination and high ecological risk of the PTEs in the worst situation

The structure of the calixarene-adorned magnetic nanoparticles 4 was determined by a combination of FTIR, TEM, and elemental analysis. Moreover, a study regarding the removal of toxic HCr2O−7 anion from aqueous solution was also carried out with the calixarene-adorned magnetic nanoparticles in solid–liquid extraction studies.

Considerable interest is continuing to be shown in the speciation of metals, metalloids, and organometals due to the dependence of their toxicity and mobility on their chemical form. This review focuses on the speciation analysis of metals, metalloids, and organometals by solid phase extraction before spectrometric detection, and all aspects of analytical speciation such as determination of oxidation states and organometallic compounds. Some applications of speciation of metals and metalloids are also presented and discussed in this review.

Hexavalent chromium, Cr(VI), is a highly toxic species, while trivalent chromium, Cr(III), is an essential trace element for humans and other organisms. In the present work, a simple, rapid, and efficient procedure for water treatment of Cr(VI) is described. Active carbon (AC) was chemically treated with HCl and NaOH for the formation of surface modified Acidic-AC and Basic-AC sorbents, respectively. In addition, AC sorbent was treated with HNO3 as an oxidizing agent and sodium sulfite as a reducing agent for the formation of Ox-AC and Rd-AC sorbents, respectively.

This study describes the synthesis, characterization, and application of a new p−sulfonatocalix[4]arenebased silica resin (calix-resin 5) for the extraction of selected metals, namely Pb, Cd, Co, Ni, Cu and Fe, from canola oil. Synthesis, morphology, purity, and elemental composition of calix-resin 5 were analyzed by FT-IR spectroscopy, scanning electron microscopy, and energy-dispersive spectroscopy.

A total of 63 newly synthesized compounds were screened in terms of PARP inhibition by cellular PARylation assay in the HeLa cell line. It was found that 19 compounds significantly inhibited the H2O2 -induced cellular PARylation. The chemosensitizer effect of these compounds in cancer cells treated with doxorubicin (doxo) was investigated. It was found that the combination of potent PARP inhibitors with doxo potentiated a cytotoxic effect, similar to that of olaparib.

: Boron is a naturally occurring trace element found in organic and inorganic complexes. Boron-containing compounds are required for living organisms for diverse metabolic functions, including nitrogen fixation in microorganisms, cell wall stability in plants, and bone and carbohydrate metabolism in animals. The number of studies about the effect of boron in biological model systems is very limited; so far, there has been no study on the correlation between boron and amyloid-beta toxicity.

Rice is particularly effective, compared to other cereals, at accumulating arsenic (As), a nonthreshold, class 1 human carcinogen in shoot and grain. Nano-zinc oxide is gradually used in agricultural production due to its adsorption capacity and as a nutrient element.
