Summary: Eutrophication is a global environmental issue that impairs water quality, threatens drinking water safety, and hinders regional economic development. This study proposes an effective technical program, utilizing a composite iron-carbon constructed wetland combined with a photocatalytic film, to restore eutrophic water. The experimental results show significant improvement in water quality after treatment, with a large number of microalgae on the wetland exerting a reoxygenation effect and enhancing the self-purification capacity of the water body. Enhancing the hydraulic performance of constructed wetlands and the activity of photocatalytic films can improve the remediation of eutrophic water bodies.

Summary: Lake eutrophication is a global environmental pollution problem. This study analyzed the degradation and recovery trajectories of Lake Gehu based on 34-year water quality monitoring data. The results showed a nonlinear recovery trajectory with a short lag time in chlorophyll-a decrease. The adverse climate change did not completely offset the positive effect of nutrient load reduction, emphasizing the importance of further attention to eutrophication control. The sensitivity of lake eutrophication increased and the total phosphorus carrying concentration reduced by 40%-60% according to the changes in algae production efficiency of total phosphorus. The water quality goal for controlling algae was determined as TP = 40μg/L (Chla = 10μg/L), which was 20% stricter than the national standard. Aquatic vegetation restoration and biological manipulation were identified as effective alternatives for controlling eutrophication.

Summary: This study investigates the efficiency of nutrient removal in a constructed wetland used to treat urban runoff. The findings show low removal efficiency for dissolved inorganic nutrient (DIN), but high efflux of dissolved inorganic phosphate (DIP). Due to short water residency and increased flow volume, the surface area of the wetland needs to be increased to cope with the current daily inputs.

Summary: This study used Lake Datong in Hunan Province, China as an example to investigate the effects of aquaculture. It was found that the lake's water quality deteriorated and became moderately eutrophic since the introduction of aquaculture in the 1980s. The lake underwent four stages of eutrophication succession, and after comprehensive management, consumer biomass decreased and submerged macrophyte biomass increased, resulting in reduced energy transfer efficiency.

Summary: This study quantified the total phosphorus loading to Lake Baiyangdian in northern China and assessed future trends and trophic state implications. Results show that under different socioeconomic scenarios, TP loading will increase only in the fragmentation scenario by 2050, mainly due to animal manure discharge. It is crucial to avoid eutrophication and restore oligotrophic state by reducing direct discharge of animal manure and increasing TP removal rates, especially in rural areas.

Summary: The study found that water quality and temperature play a key role in sediment nutrient flux in shallow, eutrophic, turbid lakes, while water depth manipulation may be less important for maximizing spring runoff nutrient retention.

Summary: Artificial floating islands (AFIs) have been proposed as a solution to nutrient pollution. Field and mesocosm experiments were conducted in Ohio to compare the performance of two native aquatic plant species. The results showed that Carex comosa outperformed Eleocharis palustris in terms of biomass accumulation and root system development. AFIs containing C. comosa had better nutrient removal capacity.

Summary: The study conducted in Lake Ulansuhai, a shallow eutrophic lake in Northern China, found that eutrophication significantly decreased CO2 emissions from the lake, while increasing CH4 emissions, resulting in a CH4 and CO2 emission ratio of approximately 2 in terms of global warming potential.

Summary: Submerged macrophytes can increase water oxygen concentrations and promote diel oxygen fluctuations, playing a vital role in regulating N2O emissions in shallow eutrophic lakes. Study in Lake Wuliangsuhai found significant diurnal variations in dissolved oxygen concentrations in submerged macrophyte areas, with water oxygen levels being a major regulator of N2O flux.

Summary: This study investigated the spatial and temporal variations of methane and carbon dioxide in the Northwest Bay of Lake Chaohu, China, which experiences frequent algal blooms. The results showed that methane concentration decreased significantly during warm seasons when algal blooms occurred, while carbon dioxide did not change substantially. River mouths acted as hotspots for carbon dioxide. The findings suggest that frequent algal blooms can absorb more carbon dioxide and release methane, making lakes an important part of the carbon budget and greenhouse gases emission.

Summary: This study evaluates the relative importance of different environmental factors on the diversity and stability of plankton communities in shallow eutrophic lakes in China. The results show that physical and chemical indicators, nutritional parameters, and light effects have a significant impact on zooplankton community dynamics, while physical and chemical parameters have the greatest influence on phytoplankton community composition.

Summary: Restoration efforts in river deltas often involve using dredged sediments to improve ecological value. This study examined the development of cattail and common reed on two types of dredged sediments, clay and mud, under different water levels in a mesocosm experiment. The results showed that sediment type influenced the growth of cattail, while water level only affected the development of common reed under inundation conditions. Both sediment types were suitable for macrophyte vegetation development.

Summary: Persistent eutrophication can lead to toxic algal blooms, posing a serious threat to drinking water safety, food security, and public health. This study proposes a new framework for analyzing the spatial patterns of nutrient loads and thresholds in large shallow lakes. The results show significant spatial differences in nutrient loads and thresholds among different areas of the lake, which are valuable for watershed nutrient management and ecological restoration of lakes.
