Summary: This study used an in situ tool, diffusive gradients in thin films (DGT), to investigate the distribution and exchange kinetics of five typical PFAS in four soils. The results showed a nonlinear relationship between PFAS masses in DGT and time, indicating that PFAS were partially supplied by the solid phase in all soils. A dynamic model called DGT-induced fluxes in soils/sediments (DIFS) was used to interpret the results and determine the distribution coefficients for the labile fraction (Kdl), response time (tc), and adsorption/desorption rates (k1 and k-1). The findings suggest that the availability of PFAS in soils is controlled by Kdl, while the release of PFAS from soils may be kinetically constrained, especially for more hydrophilic PFAS.

Summary: The study revealed that under the influence of pollutants discharged by textile plants, the concentrations of antimony compounds in the sediment of shallow lakes are relatively high. Antimony was found to be immobile in the oxygen-rich layer, but released along with other elements in the anoxic environment, depending on the redox conditions and the labile antimony content in the sediment. The mobility of antimony in shallow lakes and wetland sediments should be carefully considered when assessing the potential ecological risks.

Summary: A better understanding of the roles of fertilization in the dynamic resupply of phosphorus from soil solids to solution is necessary for optimizing sustainable phosphorus fertilizer management practices. A five-year fertilization experiment was conducted to investigate the effects of different treatments on soil phosphorus fractions and availability, as well as the kinetic phosphorus resupply using a novel simulation technique. The results showed that organic fertilization, particularly the combination of chemical fertilizer and bone meal fertilizer, had a greater enhancement effect on the phosphorus supply pool and resupply, making it an effective practice for sustainable agriculture.

Summary: Antibiotics, widely used in human and veterinary medicine, are persistent organic compounds that contribute to the development of antibiotic resistance in microbes. This review discusses the use of o-DGT technology to study the behavior of antibiotics in different environmental media. It compares different agarose diffusive gel and binding agents, explores the feasibility of o-DGT in water and soil, and analyzes the potential of using o-DGT in sediment for antibiotic measurements.

Summary: In this study, the performances of L-DGT, conventional DGT, and POCIS were compared for monitoring organic contaminants. The results showed that L-DGT had advantages in sensitivity and robustness during field deployment compared to the conventional DGT. POCIS had the highest sensitivity, but both L-DGT and DGT provided more reliable determination of time-weighted average concentrations (CW). L-DGT was more suitable for low-contaminated contexts requiring higher sensitivity, while POCIS remained the most suitable passive sampler for qualitative evaluation.

Summary: The DGT technique is a useful tool for measuring nitrogen in freshwaters and assessing the bioavailability of phosphorus in soils/sediments. However, its performance is affected by the presence of algae bloom in field water conditions, especially in measuring NH4-N. Improvement of the DGT technique is necessary for in situ measurement of nutrients in real environments. Comprehensive assessment of eutrophication levels should consider multiple environmental factors rather than just nutrient concentrations.

Summary: This study found through field experiments that drip application of phosphorus fertilizer during the cotton growing stages can increase the migration distance of phosphorus in soil, as well as improve the biomass, lint yield, and root length density of cotton. However, it also reduces the root/shoot ratio. Additionally, precise drip fertilizer application during the bud stage can also increase the DGT-P content and root length density in soil.

Summary: Understanding Se fractionation and the role of dissolved organic matter (DOM) in soil is crucial for comprehending Se mobility and bioavailability in the soil-plant system. This study found that adding cow or chicken manure with selenite can decrease Se availability in soil, and low-molecular-weight DOM-Se fractions are important sources for plant uptake of Se. DGT-Se can reflect Se uptake ability by plants and predict Se bioavailability when manure and selenite are applied simultaneously.

Summary: The study demonstrates how Trichodesmium acclimates to resource availability by upregulating iron-stress biomarker genes with decreasing Fe availability and upregulating genes involved in the acquisition of diverse P sources with decreasing P availability. Enhanced N-2 fixation within the Fe and P co-stressed transition region was associated with a distinct metabolic profile, suggesting unique physiological responses to exploit the Fe and P co-limited niche.

Summary: Determining species, concentrations, and physicochemical parameters in natural waters is important for understanding ecosystem functioning. The use of DGT devices with different thicknesses of the resin or diffusive disc provides independent information on relevant parameters. This study presents a method for determining dissociation rate constants of metal complexes and estimating metal bioavailability in environmental waters.

Summary: Diffusive Gradient in Thin Films (DGT) for organics has gained attention for studying chemical dynamics, but faces limitations in outer filter membrane and configuration, requiring further investigation; the impact of biofouling on DGT for organics needs systematic study; using DGT combined with bioassays to predict environmental mixtures' effects on biota shows promise for future research.

Summary: The study aimed to investigate the cutaneous pharmacokinetics and biodistribution of the PD-1 inhibitor nivolumab delivered locally by ablative fractional laser (AFL)-assisted passive diffusion or active intradermal injection in vivo. Results showed different pharmacokinetic and biodistribution patterns between AFL-assisted diffusion and intradermal injection, with AFL resulting in enhanced uptake after 4 hours and intradermal injection showing immediate enhanced cutaneous deposition with retention up to 2 days. These findings suggest the potential for development of individualized treatment strategies based on tumor appearance.

Summary: An urgent challenge in agriculture is to improve fertilizer efficiency to reduce the environmental impact of increased crop production. Standard soil fertilization strategies are often inefficient due to soil immobilization and nutrient losses. Foliar fertilization offers an attractive alternative, but is hindered by leaf barriers and limited nutrient translocation. Recent advances in bionanotechnology provide emerging possibilities to overcome these challenges. This review discusses how nanoparticles can be tailored with smart properties to enhance nutrient delivery to plant tissues.

Summary: Phosphorus (P) deficiency is a global issue that affects crop yield, including important food crops like potato. P status in field-grown potatoes is influenced by leaf position and time of measurement, making it difficult to accurately interpret fertilizer recommendations. The P concentration in leaf tissue changes with leaf age and sampling time, with significant variations observed. Alternative methods, such as measuring P-predict values derived from chlorophyll a fluorescence, can provide a proxy for bioavailable P in the leaf. However, photoinhibition caused by high solar irradiation can impact the accuracy of P-predict measurements, which can be mitigated by shading the plants.

Summary: Drought is a pressing issue worldwide, and selecting wheat genotypes adapted to changing climatic conditions is crucial. This study evaluated 156 bread wheat genotypes, including landraces and modern varieties, under different drought treatments. The results showed that landraces had higher yield stability and protein content under drought stress, suggesting their potential for developing drought-tolerant modern wheat varieties. Effective utilization of landraces in breeding programs is important for developing climate-resilient wheat varieties.

The results showed that modern cotton cultivars have increased total nutrient uptake but slower improvement in nutrient use efficiency. The findings highlight the potential for enhanced nutrient uptake traits in cotton.
