Summary: This study examined the spatial distribution of fluoride and manganese in groundwater and assessed overall groundwater quality using the entropy weight water quality index. Health risks associated with fluoride and manganese were evaluated through a Monte Carlo stochastic simulation method. The research found that groundwater quality is impacted by agricultural activities, industrial development, and local hydrogeological conditions, with children facing higher health risks compared to adults.

Summary: The study shows that groundwater in the Guanzhong Basin contains varying levels of Cr6+, with a significant portion exceeding the acceptable limit for drinking purposes. The presence of Cr6+ is largely influenced by hydrogeochemical factors and industrial activities. Health risk assessment reveals that residents in the study area face higher carcinogenic risks from Cr6+ exposure.

Summary: Constructed wetlands integrated with sulfur autotrophic denitrification using elemental sulfur as the carbon source have the potential to efficiently remove nitrogen from carbon-limited wastewater. The sulfur autotrophic denitrification process in the SCW enhances nitrate removal efficiency and rate. The combined CW-SCW system allows for simultaneous removal of total ammonia nitrogen and nitrate.

Summary: The study established an RM reactor with fixed AHAQ and three core strains, achieving high nitrate removal efficiency under low C/N and short HRT conditions. The reactor induced decorrelation tendencies between NRE and active extracellular organics, favored the stability of effluent organics and biological activities, and potentially enhanced electron transport activity. Despite deteriorated NRE in lower C/N, biological strategies were adapted to grow better and resist adverse conditions.

Summary: This study proposes a deep learning neural network model based on LSTM networks and particle swarm optimization (PSO) to improve flood forecast accuracy and lead time. The model outperforms other models at different stations in the watersheds and is particularly effective for flood forecasting with lead times exceeding 6 hours.

Summary: In this study, the performance of predicting soil organic carbon (SOC) in an arid agroecosystem in Iran using different datasets and machine learning algorithms was compared. The results showed that the Cubist model performed the best with the MCC dataset and the combined dataset of MCC and remote sensing time-series (RST), while the RF model showed better results for the RST dataset. Soil properties were found to be the main factors influencing SOC variation in the MCC and combined datasets, while NDVI was the most controlling factor in the RST dataset. The study suggested that time-series vegetation indices may not significantly improve SOC prediction accuracy, but combining MCC and RST datasets could produce SOC spatial maps with lower uncertainty.

Summary: This study investigated the characteristics and sources of PAHs in urban soils from two industrial cities in east India and assessed their health risks to humans. The results showed that HMW PAHs (4-5 rings) were predominant, with major sources of contamination being petroleum combustion, vehicular emissions, biomass, and coal combustion. The health risk assessment indicated some carcinogenic risk for adults, although the cumulative probability of carcinogenic risks was generally within acceptable limits.

Summary: As residential areas continue to expand in Turkey, environmental pollution, especially heavy metal pollution, has become a major concern. This study focused on mapping the pollution levels of lead (Pb) and chromium (Cr) in the city center of Ankara, Turkey using topsoil samples. The results showed that the highest concentration of Cr was found in the northwest-southeast axis of the study area, while the highest concentration of Pb was located in the center of the study area, specifically in the west of Sincan town.

Summary: Phosphorus is an essential element for organisms, but the natural phosphorus cycle has been disrupted by overexploitation and discharge into water bodies. Electrochemically induced phosphate precipitation offers a potential solution for phosphorus recovery by creating a localized high pH environment. Factors such as pH, current density, electrode configuration, and water matrix affect the performance of electrochemical systems. Future research should focus on evaluating long-term performance, developing an automatic process for harvesting deposits, and assessing economic feasibility.

Summary: This paper establishes a model framework for the multi-dimensional optimization of agricultural water and land resources management in a changing environment. The model framework comprehensively allocates resources, balances conflicting goals, and proposes alternative allocation schemes to cope with environmental changes, leading to optimal adaptation allocation plans. The feasibility and practicality of the model framework are verified through a real-world case study, showing its potential for sustainable management of agricultural water resources and land resources.

Summary: The study found that satellite-based precipitation products generally outperform model-based products, but the latter perform better in high-latitude regions and winter. ERA5 and ERA5-Land show similar spatio-temporal patterns and have their own advantages. Satellite products perform best in subregions of subtropical and tropical monsoon climate.

Summary: The lack of consistent, accurate information on evapotranspiration and consumptive use of water by irrigated agriculture is a key issue in water management in the western United States and other arid agricultural regions. Recent advances in remote sensing of ET have led to the development of various mapping methods, with the OpenET project aiming to develop a system for generating and distributing ET data.
