Summary: Phosphorus (P) is an essential natural mineral for biological processes and structures that support life in plants and animals. This study aimed to determine the phosphorus (P) sorption characteristics of some soils and derive relevant parameter estimates for predicting and managing phosphorus as well as understanding their relationship with soil properties. The results showed that the amount of phosphorus adsorbed increased with depth, with different soils requiring varying levels of P fertilizer. Correlation analysis revealed significant relationships between soil characteristics and sorption parameters.

Summary: Lead (Pb) is a highly toxic heavy metal that can enter the biological system through the food chain, and lead ion (Pb (II)) can be released into the environment from natural and anthropogenic sources. Among various remediation techniques, adsorption is considered effective for its economic and versatile properties. The study showed that the CS-AC-PVA composite beads have better adsorption capacity for Pb (II) compared to lone CS, AC, and CS-AC beads, with a 44% increase compared to CA-AC beads. The adsorption capacity of CS-AC-PVA beads for Pb (II) was highest at 25 degrees C, following the Freundlich isotherm model with increasing concentrations and decreasing temperatures. This demonstrates the potential of CS-AC-PVA composite beads as an adsorbent for environmental remediation of Pb (II) from aqueous solutions.

Summary: The study reveals the sorption characteristics of direct dye onto flax fibers during the dyeing process, showing that the increase in dye concentration reduces dye consumption while longer dyeing time increases exhaustion. The amount of adsorbate on the fibers rises with initial concentration and dyeing time. Various models can be used to describe the adsorption process, with the Flory-Huggins model standing out for its ability to describe sorption and achieve high coefficient of determination values.

Summary: The modeling of experimental data is important for predicting the mechanism of adsorption systems. Experimental data of pristine and SnO2 functionalized single walled carbon nanotubes with nitrogen dioxide and ammonia gases at varying concentrations were compared with theoretical isotherm models. The Freundlich isotherm showed the best compatibility with the experimental results, indicating the heterogeneous nature of the surface. The calculated constants for the models suggested an increased adsorption capacity in the case of functionalized single walled carbon nanotubes, likely due to increased heterogeneity and enhanced surface area.

Summary: The kinetics of adsorption phenomena are analyzed using both local and non-local kinetic equations of the Langmuir type. The results show that the dependence of the adsorption coefficient on the density of adsorbed particles leads to the occurrence of adsorption effects in both saturation and non-saturation regimes.

Summary: Potassium availability to plants is influenced by the adsorption characteristics of soil, with different soil series showing varying levels of K adsorption. The Freundlich model proved to be a better fit for explaining potassium adsorption behavior, with soil physico-chemical characteristics such as clay content, alkaline pH, and organic matter content playing a significant role in K adsorption.

Summary: Clean soil is important for human health. This study used a mixed reactor to wash contaminated soil with petroleum derivatives and investigated the adsorption process of benzene and toluene using CuO nanosorbent. A cost-effective method was used to produce high-purity CuO nanosorbent. The effects of initial concentration, contact time, and pH on adsorption efficiency were studied. Results showed that CuO nanosorbents have a high capacity to adsorb benzene and toluene, with the Langmuir model providing the best fit for the adsorption data.

Summary: This study assessed the vulnerability of groundwater resources in an industrial area, focusing on the dispersion of chromium and the impact on water quality. Different bio-adsorbent materials were tested for their adsorption of hexavalent chromium, showing enhanced adsorption compared to natural bio-adsorbents after modification. The study also found that the reactions between chromium and bio-adsorbents followed pseudo-second-order kinetics and were exothermic.

Summary: In Croatia's Podravina region, the heavy exploitation of natural gas, thriving agricultural industry, and transportation hub have led to significant lead pollution. This study focused on the bioaccumulation of lead in various organs of hares, particularly the liver, kidney, muscle, and brain, and its impact on the organism's oxidative status. The research also explored a potential ionic mechanism for lead exchange in the brain. The findings showed that long-term lead exposure negatively affected the oxidative status of hares, with the brain and muscles experiencing the strongest toxicity.

Summary: The transport behavior of Imidacloprid (IMI) in Mediterranean soils in Croatia was studied using column experiments. The results showed that IMI has a high affinity for soil organic matter and does not exhibit sorption activity with clay. Hematite, on the other hand, acts as an active sorbent for IMI and increases the leachability of other insecticides. The study suggests that the risk of IMI accumulation in soils is higher than the risk of leaching contamination, emphasizing the importance of continuous monitoring for soil health protection programs.

Summary: This study investigates the toxicity and cellular response to metal ions released by fixed orthodontic appliances on gastrointestinal tract cells. The eluates of archwires, brackets, ligatures, and bands were tested for their prooxidant effect, cytotoxicity, and genotoxicity on four different cell lines. The results show that most eluates were toxic to CAL 27 cells and that CaCo-2 cells were the most resistant. The eluates induced free radical formation in AGS and Hep-G2 cells, and eluates containing Cr, Mn, and Al showed slight prooxidant effect and genotoxicity.

Summary: In the pathogenesis of endometriosis, a number of pathological reactions occur. Proteins secreted in the urine are thought to interact with each other and stimulate the pathological processes in endometriosis. An analysis of urine samples from patients with endometriosis and control groups revealed 17 proteins that showed statistically significant differences in concentration. These proteins are involved in various functions related to the disease and may serve as potential biomarkers for endometriosis.

Summary: No clear conclusions can be drawn on ion release from orthodontic appliances due to complex interrelations of multiple factors. This study investigated the morphological and chemical changes of four parts of a fixed orthodontic appliance and analyzed the ion release profiles using SEM/EDX and ICP-MS techniques. The results showed variations in surface morphologies among different parts of the appliance and observed differences in ion release. SEM/EDX proved to be less sensitive than ICP-MS in detecting ion release.
