Summary: Aquatic pesticide pollution caused by pesticide use has led to the implementation of mitigation measures in many countries. However, detecting significant improvements in water quality and attributing these improvements to specific mitigation measures is challenging due to the large interannual variability of pesticide losses. This research addresses the gap in knowledge regarding the number of monitoring years or effect size needed to detect significant trends in water quality.

Summary: A study of Lake Tahoe found that the lake's water quality is declining due to algae and fine sediment, leading to a decrease in water clarity. To maintain water clarity, wastewater is exported out of the basin. Over the past 25 years, nitrate loads have decreased, while ammonium loads initially decreased and then continued to increase after 2005, and organic phosphate loads showed significant increases between 2000 and 2005.

Summary: Freshwater ecosystems are under increasing threats from multiple anthropogenic stressors, such as sewage discharge and agricultural/urban land use, which independently impact water quality. However, the combined effects of these stressors are still poorly understood. In this field study, we evaluated the effects of sewage discharge and land use on nutrient concentrations, sewage fungus presence, and communities of macroinvertebrates and benthic algae. Our results showed that sewage discharge significantly affected water quality and benthic riverine communities, regardless of surrounding land uses. Agricultural inputs may have a greater impact on reducing the abundance of sensitive invertebrate taxa compared to treated sewage discharge. The study highlights the importance of improving wastewater treatment processes and reducing agricultural pollution to protect vulnerable freshwater communities.

Summary: This article reviews the history of surface water quality monitoring in China since the reform and opening up, and analyzes the temporal and spatial patterns of surface water quality. Overall, the quality of surface water has shown a pattern of fluctuating changes, rapid deterioration, fluctuations stalemate, and rapid improvement. However, the current status of surface water quality in China is still polluted, and there is a gap between the water quality status and the goal of building a well-off society. Therefore, in addition to strengthening the control of surface water quality, it is necessary to enhance the work of risk identification, early warning, and regulation implementation for the surface water environment.

Summary: This study proposes a new climate-informed methodology for estimating flood-frequency curves under non-stationary future climate conditions. By developing an asynchronous, semiparametric local-likelihood regression model, the researchers relate flood moments to climate variables and estimate the first two marginal moments of the underlying distribution. The proposed methodology is applied to 40 streamgages in the US and evaluated using historical and projected climate data from Global Circulation Models, showing good agreement in humid basins but higher uncertainty in arid basins.

Summary: This study rigorously compares different nonstationary flood frequency analysis methods for modeling changes in both the central tendency and variability of annual peak-flow series. It evaluates the performance of these methods using Monte Carlo experiments and identifies the statistical properties of the annual maximum series that affect the performance of nonstationary models. The study highlights the need for more flexibility in design-flood adjustments and suggests further comparison of regional nonstationary models.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
