Summary: This study investigated the accumulation, risk, distribution, and sources of heavy metals in 62 lakes along the Yangtze River. It found that most lakes were contaminated with Cd, with higher ecological risk in the middle reach and southern bank of the Yangtze River. The study also revealed that Cr originated from the natural environment, while Zn, Cu, Pb, Cd and As were affected by human activities.

Summary: Soil heavy metal contamination caused by mining activities is a global issue that threatens public health. Biochar, as an environmentally friendly soil remediation agent, can effectively immobilize heavy metals. However, research on biochar remediation in mining areas is limited and the remediation effect is influenced by various factors. It is necessary to systematically unravel the knowledge of biochar remediation and provide guidance for future studies.

Summary: The study revealed that the soil in the gold tailings pond is heavily polluted by Cu, with heavy metal pollution levels positively correlated with distance from the tailings pond center. The tailings pond could potentially become a source of Cu pollution in the surrounding environment, posing a threat to environmental safety and human health. Plants such as Chinese brake, Ramose scouring rush, and Manyflower silvergrass show promise for phytostabilization of Cu.

Summary: Lime application significantly increases rice yield and soil pH, while reducing Cd concentrations in grains. The effects of lime on rice yield vary depending on soil pH and lime application rates, with higher lime application leading to greater reduction in Cd concentrations. Lime application at rates exceeding 1.0 and 6.0 t ha(-1) can effectively reduce Cd concentrations in grains to meet food safety standards.

Summary: A new heavy metal adsorbent based on humic acid residue modified by sulfuric acid (HAS-SO4) was developed, showing improved adsorption capacity for Hg2+ and Pb2+. The adsorption process followed Langmuir isotherm and pseudo-second-order kinetic models. HAS-SO4 effectively passivated Hg2+ and Pb2+ in contaminated soil, reducing their leaching risk and changing their morphology.

Summary: Using national multi-purpose regional geochemical survey data, this study systematically summarizes the pollution levels and health risks posed by 8 heavy metals in urban soils of 86 cities in the Yangtze River Economic Belt. The study found that Hg and Cd contamination in urban soils of the region is most prominent, while Cr and Ni contamination is almost nonexistent. The type of industrialization and urbanization history affect soil heavy metal pollution, and the influence of geological background cannot be ignored. The major pollutants in urban soils of Hunan and Hubei provinces are Cd, As, Pb, and Zn, while Hg pollution occurs in Zhejiang and Jiangsu provinces. The study also found that heavy metals generally pose low non-carcinogenic and carcinogenic risks to adults, but caution should be given to minors in certain cities.

Summary: Water bodies, such as lakes and reservoirs, provide important ecosystem services. This study compares the morphometric features of natural lakes and reservoirs using a global dataset. The results show that natural lakes have a larger volume-area scaling exponent and cover a wider range of volumes compared to reservoirs. Additionally, the scaling relations of lakes are more influenced by land cover and terrain compared to reservoirs.

Summary: This study investigated the differences in water storage dynamics between wetlands within the same wetlandscape. The researchers found that wetlands in different positions exhibit two distinct storage behaviors. Headwater wetlands are able to store excess water to buffer floods, while downstream wetlands experience seasonal low water levels. The study also revealed that headwater wetlands have complex and patchy inundation patterns, while downstream wetlands are characterized by prolonged low-water states.

Summary: Non-floodplain wetlands (NFWs) are important and fragile freshwater systems. The lack of consistent terminology and regional biases hinder global collaboration. However, there is more that unites NFW research and management efforts. Improved cohesion in classification and terminology, as well as a focus on wetland functionality, can facilitate better collaboration.

Summary: This study addresses the relationship between climate change, variability, soil moisture, and the Lake Baikal catchment. It finds that rain-driven floods significantly affect the water level and distribution of dissolved and suspended matter in Lake Baikal. Using various statistical methods, the study evaluates the impact of meteorological parameters on river flow and identifies a significant decreasing trend in average and maximum river flow in the eastern part of the Selenga River basin. The study also reveals the sensitivity of catchments with steep slopes and high precipitation variability to precipitation change.

Summary: The city of Moscow, Russia experienced two major flooding events in 2020 and 2021 due to historical rainfall. A pioneer assessment of the impact of climate change and urbanization on flooding hazard and water quality of the urban Setun River was conducted. The study reveals a significant increase in moderate climate change indices and a non-linear combined effect of climate change and urbanization, resulting in a higher frequency of extreme floods and changes in water regime features.

Summary: This study provides a high-resolution assessment of sediment behavior in the Lena River, revealing significant differences in suspended sediment transport between different sections of the river. In the middle reaches of the river, sediment concentrations decrease during peak flows, while bed and lateral scour result in increased sediment load during low water seasons. The distributary system of the Lena delta experiences increased sediment transport primarily in the downstream direction, especially along major distributary channels.

Summary: The wetland area in agricultural landscapes has been significantly reduced for crop production, but there is now a growing recognition of the negative consequences of wetland loss. As a result, there is a trend towards re-establishing wetlands to achieve multiple ecosystem services. This review highlights the need to focus on wetlandscapes rather than individual wetlands to achieve societal and environmental goals, and discusses key factors for planning wetland re-establishment at the landscape scale.

Summary: This study evaluates the accuracy of the China Meteorological Forcing Data Set (CMFD) in the Shanghai megacity and improves the accuracy of CMFD precipitation. The performance of CMFD precipitation varies at different time scales, with better accuracy at the monthly scale. The Geographic Differential Analysis (GDA) method is used to calibrate the CMFD precipitation data set, resulting in improved capability, especially at the sub-daily and daily scales. The calibrated CMFD provides reliable precipitation estimates and captures more extreme precipitation events, making it valuable for hydrological and meteorological hazard monitoring and assessment in the Shanghai area.
