Summary: This study found that the application of sulfur and phosphorus can significantly increase the uptake of selenium by pak choi, while high levels of sulfur and phosphorus can also inhibit the absorption of selenium to a certain extent. The bioavailability of selenium in soil is affected by the competitive adsorption of S and P, as well as changes in soil pH.

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 availability of soil nitrogen for plant uptake can be affected by various soil factors, and conventional extraction techniques may affect the measurement of plant-available N concentrations. The diffusive gradients in thin-films (DGT) technique can overcome these limitations and has been successfully used to estimate the plant-available fractions of nutrients in soils. Therefore, evaluating the use of DGT for measuring NO3- and NH4+ in different soils and examining the factors affecting the plant-availability of these ions in soils is important.

Summary: In this study, the effects of two different organic amendments on trace metal transfer from soils to crops were investigated. The addition of compost to soil resulted in lower trace metal concentrations in lettuce compared to soils with no amendment. Biochar also showed a reduction in Cr and Pb uptake by lettuce, with higher levels of biochar leading to greater reductions. The DGT method was found to be faster and more cost-effective in predicting metal uptake by plants compared to BCR sequential extraction.

Summary: This study investigated the potential use of diffusive gradients in thin films to sample organic compounds (o-DGT) for wastewater-based epidemiology. Results showed that the HLB resin performed better than the XAD 18 and XDA-1 resins, with methamphetamine and heroin being the two most popular illicit drugs consumed among the studied populations. Overall, the findings demonstrate that o-DGT passive samplers are a promising tool for WBE studies.

Summary: The bioavailability of selenium in seleniferous soils is influenced by its distribution, with only small proportions found in soluble and exchangeable forms. Selenium primarily exists in organic matter-bound fractions, showing a significant positive correlation with soil organic matter. The use of DGT technology accurately assesses selenium bioavailability in naturally seleniferous soils.

Summary: This study investigated the effect of natural zeolite amendment on the bioavailability of heavy metals in contaminated soil. The addition of zeolite resulted in a significant decrease in Cd and Pb concentrations, as well as a decrease in Cu, Cr, and Zn concentrations. The resupply of metals from the soil solid phase to the soil solution was reduced in the samples with added zeolite.

Summary: Dynamic processes of organic contaminants in sediments have toxicological implications in aquatic systems. The study used DGT devices to measure the flux and exchange rates of antipsychotic compounds in sandy sediments. The results showed the continuous removal of these compounds from the sediments and their movement to the adjacent sediment solution. A dynamic model was used to determine the rate constants and distribution coefficients of the antipsychotics. The study highlights the importance of understanding the desorption kinetics of contaminants in sediments.

Summary: This study investigated the effects of pH and major anions on the toxicity of selenate (Se(VI)), and developed models based on the biotic ligand model (BLM) and free ion activity model (FIAM) concepts. Results showed that increasing pH values alleviated Se(VI) toxicity, and H2PO4- and SO42- competed with Se(VI) for binding sites affecting toxicity. The extended BLM performed better in predicting wheat root elongation when considering SeO42- and HSeO4- toxicity and competitive effects of H2PO4- and SO42-.

Summary: In order to solve the problem of excessive heavy metals in farmland soil, research efforts are needed to screen for the soil passivator materials. This study investigated the effects of combined passivators on cadmium availability in soils and uptake by pakchoi. The results showed that sepiolite, calcined lime, and polyacrylamide (PAM) significantly decreased the available Cd content in soils. The combination of calcined lime+PAM+sepiolite was the most effective in decreasing the available Cd content in soils and reducing Cd uptake by pakchoi.

Summary: It is uncertain whether degradable film mulching is a viable alternative to non-degradable film mulching for improving crop productivity and soil environmental conditions. A three-year field experiment was conducted to evaluate the effects of different degradable films and traditional plastic film on soil properties and peanut growth performance. Results showed that degradable films increased peanut yields compared to no mulching, but decreased yields compared to traditional plastic film. The best alternative film was found to be aliphatic polyester polylactic acid-based film due to its positive effects on soil environment and crop yield, as well as its superior degradation properties.

Summary: UV irradiation was found to exacerbate the damage to disposable masks over time and increase the release of microplastics (MPs) and nanoplastics (NPs) from the masks. The middle layer of the mask was damaged first, followed by all layers as the irradiation time increased. There was no significant difference in the quantity of M/NPs released at different irradiance levels, but the release of M/NPs increased exponentially with increasing UV irradiation time.

Summary: This paper uses a probabilistic method to analyze the average behavior time of widespread fatigue damage (WFD) in an aircraft multi-site damage (MSD) structure and simulates the entire process from crack initiation to structural failure. By statistically analyzing the test data, the probability distribution of crack initiation life and growth rate is obtained and expressed through the randomization of variables. Through the Monte Carlo method, the initiation, propagation, and connection of multiple cracks in the MSD structure to the occurrence of WFD are realized. The calculation results are in good agreement with experimental data and can accurately predict the life of MSD structures under a certain reliability.

Summary: Soil Cd pollution is a serious concern in China due to its impact on human health through the food chain. This study investigated the effects of amendments on Cd availability in contaminated soils under corn-wheat rotation, showing that lime and hydroxyapatite can reduce Cd availability, while pig manure can increase certain Cd fractions. Combined amendments can decrease grain Cd concentrations and increase crop biomass, with more significant effects observed in black soil.
