Summary: The study demonstrates the overall applicability of the novel sonoreactor VialTweeter as a tool for extracting trace elements from soil samples in environmental monitoring. The proposed sonoreactor-assisted extraction methodology offers advantages of shorter pretreatment time and reduced sample and reagent usage compared to standard acid digestion. Validation results against the standard acid digestion vary for different analytes, with cadmium showing the best results without systematic error. Corrections are required for copper, lead, arsenic, and zinc determination when using the proposed US extraction plus ICP-MS.

Summary: Lake Victoria, the second largest freshwater lake and largest tropical lake in the world, has a rapidly growing population in its transboundary catchment, potentially impacting water and sediment quality. The study analyzed trace elements, organic matter, and phosphorus in sediment layers near coastal cities in Uganda, finding no critical trace element contamination but detecting changes in element distributions caused by anthropogenic influences. Industries near Jinja were found to elevate copper content in sediments, potentially harming aquatic habitats, while increasing organic matter in sediments near River Nzoia's estuary indicated soil erosion and water hyacinth blooms. The study emphasizes the need for the entire catchment area to ensure a healthy aquatic ecosystem in Lake Victoria.

Summary: Pollution poses a major threat to marine life, and trace elements are highly toxic pollutants in this environment. Zinc, an essential trace element for biota, becomes toxic at high concentrations. Sea turtles, with their longevity and widespread distribution, are good bioindicators for trace element pollution, accumulating these elements in their tissues over the years. This study compared the bioaccumulation of zinc in the liver, kidney, and muscles of 35 green sea turtles from Brazil, Hawaii, the USA (Texas), Japan, and Australia. The results showed that zinc was present in all specimens, with the highest concentrations in the liver and kidneys. The findings of equal zinc values in the liver suggest a pantropical distribution pattern for this metal, possibly due to its essential nature and bioavailability in marine environments. This study highlights the importance of understanding the distribution patterns of trace elements in marine biota for conservation purposes and suggests that green turtles can serve as useful sentinel species.

Summary: This study examined the ability of acid-based natural deep eutectic solvents (NADES) to co-extract glycyrrhizic acid (GA) and trace elements from licorice roots. The results showed that lactic acid-based NADES had higher extraction efficiency for GA compared to other tested NADES. The recovery of trace elements by all tested NADES was low. Calculations indicate that the NADES extracts of licorice roots are nontoxic and pose no health risks.

Summary: The only known natural samples of high-pressure mantle constituents are mineral inclusions in diamonds, and their origin and formation have been a subject of debate. By analyzing trace elements in olivine crystals from South Africa, researchers have found evidence suggesting that these crystals formed in the deep upper mantle and potentially in the mantle transition zone. These findings provide insights into Earth's early mantle evolution and the formation of ancient continental and oceanic crust.

Summary: Thermoacidophilic Cyanidiales have a competitive advantage in extreme metal-rich environments. Cyanidioschyzon merolae (Cm), Cyanidium caldarium (Cc), and Galdieria partita (Gp) were found to effectively remove hexavalent chromium [Cr(VI)]. Cm and Gp could remove 168.1 and 93.7 mg g-1 of Cr(VI) at pH 2.0 and 7.0, with a significant portion being reduced to trivalent chromium [Cr(III)]. The presence of Cr(OH)3 was observed and correlated with the high sorption capacity of Cm and Cc at pH 2.0. These findings suggest that Cyanidiales have potential for environmentally-friendly and sustainable remediation of Cr(VI).

Summary: This study comprehensively evaluated the accumulation, distribution, and potential risks of antibiotics in agricultural soils on a global scale. The results showed that 56 types of antibiotics were detected with concentrations ranging from undetectable to over 7000 μg/kg. Tetracyclines, macrolides, sulfonamides, and fluoroquinolones were the most accumulated antibiotics. East China was identified as a hotspot for antibiotic contamination. Vegetable fields and orchards had higher antibiotic accumulation compared to croplands. The level of antibiotics decreased with increasing soil pH and organic matter content. Further research on the impacts of antibiotics on soil ecological function and a whole-chain approach for antibiotic reduction and soil remediation are needed.

Summary: This study used non-invasive micro-test technology (NMT) to investigate the mechanism of cadmium (Cd) uptake in the roots of Amaranthus hypochondriacus. The results showed that Cd2+ influx was highest near the root tip. Various inhibitors and blockers had different levels of inhibition on Cd absorption, with Ca2+ channel blockers causing the greatest reduction in net Cd2+ flux. The study suggests that Cd uptake in A. hypochondriacus roots is mainly through Ca2+ channels. The findings contribute to the understanding of Cd uptake and membrane transport pathways in Cd hyperaccumulators.

Summary: In this study, hydrogen radicals were found to be a new pathway for the production of hydroxyl radicals, which increased the dissolution of cadmium sulfide and the solubility of Cd in paddy soils. Soil incubation experiments showed that the bioavailable Cd concentrations in flooded paddy soils increased by 8.44% after 3 days of aeration. The presence of hydrogen radicals in aerated soil sludge was observed for the first time. Electrolysis experiments confirmed the association of CdS dissolution with free radicals. The application of biochar decreased soil DTPA-Cd by 22-56% through multiple mechanisms, including the quenching of radicals and stimulation of Fe/S-reducing bacteria.

Summary: The conversion of organic matter and phosphorus during the composting process of vegetable waste is influenced by the addition of microbial inoculants. This study investigated the effects of straw-decomposing microbial inoculant (SDMI) on the stability of organic matter and activation of phosphorus in the composting of vegetable waste. The addition of SDMI promoted the degradation of dissolved organic carbon, improved phosphorus stability, and enhanced the thermal stability of organic matter. The results showed that stable forms of phosphorus, such as aluminum phosphate and iron-containing phosphate, were the main forms of phosphorus in the final compost. These findings provide a basis for producing high-quality vegetable compost products and improving the reutilization potential of vegetable waste.
