Summary: This study investigated the sorption mechanisms and influencing factors of yttrium (Y), a rare earth element, on paddy soil. The results showed that the sorption behavior followed a pseudo-second-order model and was a spontaneous endothermic reaction. The maximum sorption capacity of Y decreased with increasing soil particle size and the presence of phosphorus and pH of the solution affected the sorption process. These findings provide important insights for the management and remediation of rare earth element-contaminated soils.

Summary: This study aims to evaluate the effectiveness of the integrated approach combining surfactant-assisted soil washing and cork granules for removing lindane from contaminated soil. The results show that cork granules can efficiently retain lindane and that soil washing with surfactants can separate lindane from soil. However, the integration of both treatments is not as efficient as expected and hinders the sorption of lindane.

Summary: Phosphorus is an essential element for plant growth and animal health. Most of the phosphorus released by human activities is found in solid wastes such as sewage sludge, animal manure, and wetland plants, increasing the risk of water contamination. This study reviews the migration and transformation mechanisms of phosphorus during thermal treatment of various solid wastes, with a focus on the potential applications of phosphorus-enriched hydro/bio-char. The distribution and speciation of phosphorus are affected by feedstock properties, thermal technique, and reaction conditions, which in turn affect the applications of hydro/bio-char. The production of phosphorus-enriched hydro/bio-char from solid waste is a promising method for both phosphorus reclamation and solid waste treatment.

Summary: This study explores the interaction between triclosan (TCS) and its primary metabolite, methyl triclosan (MTCS), on different sorbents. Results show that MTCS has higher sorption capacity and affinity than TCS, with competitive sorption observed between them. The presence of TCS can facilitate the sorption of MTCS at high concentrations, while the effects of competitive and cooperative sorption between multiple contaminants vary with solution pH. These findings are important for evaluating the environmental risk of microplastics and TCS in soil.

Summary: New research indicates that sustainable and fossil fuel-driven economic growth can contribute towards improving food security in Sub-Saharan Africa. Phosphorus availability is a major barrier to food security, and pathways towards sustainability or fossil fuel reliance have different impacts on food security. Prioritizing sustainable economic growth and avoiding nationalist ideologies are key to enhancing food security in the region.

Summary: In this study, a new flexible fitting model is introduced to validate the water sorption characteristics of the components in the stratum corneum. The results show that the lipids content has a negligible effect on the sorption of stratum corneum, and the overall sorption behavior can be well explained by the rule of mixtures.

Summary: The study investigated the competitive sorption and desorption of Zn, Ni, and Pb in acidic Olivier loam soil through stirred-flow experiments. It was found that metals with higher affinity could displace those with lower affinity. A two-site competitive kinetic model effectively described the experimental data and improved upon single-ion models in predicting competitive interactions between species in stirred-flow experiments.

Summary: Homegrown eggs from free-ranging laying hens often contain elevated concentrations of perfluoroalkyl acids (PFAAs). Soil is the major source of exposure, and vegetables and earthworms also contribute to the burden of PFAAs in eggs. Predictive models based on soil concentrations have been successfully developed to assess the risk of PFAAs in homegrown eggs and remediation measures have been proposed.

Summary: The widespread use of pharmaceuticals leads to increasing presence of them in the environment. This study investigated the behavior of four different drugs in soil and sediment, finding that cefdinir had the highest sorption affinity, while memantine and praziquantel tended to be present in water. pH and ionic strength had effects on the sorption of drugs.

Summary: This study investigated the interaction of physiologically relevant metal cations with polyphosphate complexes in polyphosphate-accumulating organisms (PAOs), revealing that Magnesium (Mg) and Potassium (K) have a significant impact on the stability of the complexes. Molecular dynamics simulations showed that Mg-polyphosphate complexes were the most stable, while K-polyphosphate complexes were the least stable, suggesting a role in polyphosphate bioavailability. This research provides insights into the mechanistic role of metal complexation in the phosphorus cycling traits of PAOs in engineered and natural systems.

Summary: Phosphonate-based herbicides, including glyphosate, glufosinate, and fosamine, can mobilize and be transported in quartz-enriched agricultural soils due to their interactions with calcium and sodium. The mobility of glyphosate was found to be influenced by both the mineral interfaces and the initial wetness of the soil. These findings provide new insights into the soil mobility of phosphonate-based herbicides and highlight the importance of considering soil properties for their effective and sustainable use.

Summary: Soil bacteria employ various strategies to overcome the limitation of inorganic phosphorus in soils by secreting extracellular enzymes to degrade organic phosphorus and utilizing specific transporters and intracellular metabolic pathways for phosphorus recycling. The activities of phosphatases are influenced by soil environmental conditions. Regulatory mechanisms play a crucial role in the production of phosphatases, expression of transporters, and metabolic changes in response to phosphorus availability.

Summary: This study elucidates the metabolic mechanisms facilitating gluconeogenic fast-growth phenotypes in Pseudomonas putida and Comamonas testosteroni, two Proteobacteria with distinct metabolic networks. P. putida relies on a cyclic connection between the Entner-Doudoroff and Embden-Meyerhoff-Parnas pathways, while C. testosteroni bypasses the oxidative pentose phosphate pathway during gluconeogenic growth. Both species deplete protein investment into connected glycolysis pathways to minimize futile carbon cycling and favor gluconeogenic metabolism.

Summary: This study quantified the oxygen isotope exchange kinetics between Pi isotopologues and water using Raman spectroscopy and 31P nuclear magnetic resonance (NMR) during the PPase-catalyzed 18O-16O isotope exchange reaction. The results showed that both Raman spectroscopy and NMR methods are equally applicable for monitoring the oxygen exchange kinetics between Pi isotopologue and water. However, the reliability of these methods is lower below 1% abundance and requires high concentrations of phosphorus (P).

Summary: Microbial platforms are crucial for a sustainable energy future and can process aromatic carbons from lignin and plastic feedstocks. Comamonas species are promising bacterial candidates due to their ability to use natural and xenobiotic aromatic compounds, and they often have genetic constraints that prevent competition with sugars. However, the metabolic reactions of these species and their regulatory mechanisms are not well understood.
