Summary: The study investigates the individual degrading behavior of bacterial strains isolated from glyphosate-degrading stream biofilms, revealing different and complementary glyphosate degradation pathways for bacteria co-existing in stream biofilms. Different bacterial strains showed variations in the degradation speed, pathway utilization, and accumulation of degradation products for glyphosate and its metabolite AMPA.

Summary: Recent studies have found that glyphosate and its metabolite, AMPA, can accumulate in plants and have an impact on non-target plants. This study investigated the effects of indirectly spraying glyphosate on Helianthus annuus L. plants. The results showed that glyphosate caused morphological and histological damage to the plants, leading to reduced growth and biomass. Both glyphosate and AMPA were detected in all parts of the plants, indicating that glyphosate can be incorporated into plants even through indirect application.

Summary: This research investigates the degradation of glyphosate and finds temperature-dependent preferences for the reaction pathways. Glycine pathway becomes more preferred as reaction time and temperature increase. The findings suggest possible ways to bias glyphosate degradation towards safer products and reducing overall environmental toxicity.

Summary: This study aimed to investigate the effects of different glyphosate usages on harvested grain/seed contamination. The results showed that there were no residues in the harvested spring wheat grain or spring oilseed rape seeds when glyphosate was applied at pre-emergence. However, glyphosate and its metabolite, aminomethosphonic acid, were detected in grain/seeds when glyphosate was used at pre-harvest, although the amounts did not exceed the maximum residue levels. Glyphosate residues remained in grain/seeds at steady concentrations for longer than one year, mainly concentrated in wheat bran and oilseed rape meal.

Summary: The study successfully isolated a novel bacterial strain, Y16C, which efficiently degrades glyphosate and its main metabolite AMPA. The strain was also found to tolerate and degrade AMPA at high concentrations and accelerate glyphosate degradation in soil by inducing changes in soil microbial community. This suggests that strain Y16C may be a potential microbial agent for bioremediation of glyphosate-contaminated soil.

Summary: Glyphosate, one of the most widely used herbicides globally, has raised concerns about its potential impact on human health. Biomonitoring studies have played a crucial role in assessing human exposure to glyphosate and providing valuable insights into its distribution and metabolism in the body. Research has shown that glyphosate and its major degradation product, aminomethylphosphonic acid (AMPA), have been found in different human specimens, with urine being the dominant sample. Higher levels of glyphosate and AMPA have been observed in Asian populations and among occupational groups. Children may have increased susceptibility to glyphosate exposure or different exposure patterns compared to women and adults.

Summary: The study found that wetland biofilms can remove contaminants such as glyphosate through bioconcentration and metabolism. The concentrations of glyphosate in biofilms were several orders of magnitude higher than in the surrounding water, and bioconcentration factors and metabolic patterns indicated that biofilms have the ability to degrade and absorb glyphosate.

Summary: Agro-industries need to adopt effective strategies for cautious use of agrochemicals to protect public health. The key lies in scientific research and education for new developments and environmental protection. Diagnosis on glyphosate use, risk assessment on human health, and recommendations on regulated use and mitigation of adverse effects are essential.

Summary: This study evaluated the urinary levels of Glyphosate and its metabolite aminomethylphosphonic acid in Spanish breastfeeding mothers, with a significant relationship found between intake of eggs and fruits and Glyphosate levels in urine. The calculated estimated daily intakes and hazard quotients showed low health risk expected for the population under study.

Summary: There is limited data on children's exposure to glyphosate in Europe. The collected data from five European countries showed that the current population studied had low concentrations of glyphosate in their urine and no immediate health risks. However, there is ongoing discussion about the carcinogenic effects of glyphosate and uncertainty regarding the effects of other substances related to glyphosate.

Summary: Biosorption using phosphorylated hazelnut shell waste (FHS) is a promising method for lithium removal and recovery. This study investigated the performance of a continuous-flow packed-bed column system using FHS for ultra-low level lithium removal. The results showed that the lihium biosorption capacity of the FHS column was unaffected by the bed height, but decreased with increasing flow rate.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.

Summary: Analysis of in vivo exposure to traditional Chinese medicine using mass spectrometry is helpful for identifying effective ingredients and developing new drugs. This study focused on Forsythia suspensa (Lian Qiao) and used metabolomics technology to explore its in vivo exposure. By comparing the differences before and after administration, a complete set of nontargeted analysis strategies for TCM exposure was established. The study identified 393 Lian Qiao-related chemical components in mice after administration, including prototypes and metabolites. This study provides a reference for research on the active ingredients of Lian Qiao in vivo.
