Summary: Bivalve aquaculture can help mitigate eutrophication by extracting nitrogen from estuaries. However, its effectiveness depends on various factors such as bivalve species, bay geomorphology, and climate change. Mussels are more effective than oysters in nutrient mitigation, and open systems are more resilient to change than closed ones. The study also found that increasing bivalve biomass increases nutrient mitigation potential.

Summary: The study found that nutrient concentrations were higher in macro-tidal estuaries, leading to lower levels of dissolved oxygen and impacting the community structure of mesozooplankton. The copepod community in micro- and meso-tidal estuaries was dominated by meso- and euryhaline species, while in macro-tidal estuaries, euryhaline and coastal species were dominant, with an increase in jellyfish prevalence during the post-monsoon period.

Summary: Eutrophication and algal blooms are significant environmental challenges for lakes worldwide. This study examined the relationships between nutrient levels (total nitrogen and total phosphorus) and chlorophyll a in Chinese Lake Taihu from 2005 to 2020. The results showed robust linear relationships, and recommended nutrient thresholds for the lake. Additionally, the study found that factors such as temperature, water level, wind speed, nitrogen to phosphorus ratio, and grazing influenced the sensitivity of chlorophyll a to nutrients, and atmospheric stilling was identified as a key climatic factor affecting algal blooms in Lake Taihu.

Summary: Analyzing over 5000 lakes globally, researchers have found that lakes preferentially retain phosphorous over nitrogen, exacerbating the imbalance of nutrient cycles caused by human activities. The greater retention of phosphorous leads to an elevation in the nitrogen to phosphorous ratio in lake outflows, further worsening the global ecosystem's nitrogen-phosphorous imbalance.

Summary: Different land uses have significant impacts on the primary production of aquatic organisms and the formation of autochthonous organic carbon (AOC). This study conducted a large-scale field simulation experiment over a hydrological year and found that phytoplankton are co-limited by nitrogen (N) and phosphorus (P), while submerged plants are limited by carbon (C). Chlorophyta and Bacillariophyta exhibit a stronger competitive advantage than Cyanophyta in environments with high carbon but low N-P. The contributions of phytoplankton and submerged plants to AOC formation vary seasonally, but their overall contributions to AOC concentrations in water are similar.

Summary: Narragansett Bay is a representative urbanized estuary in New England, USA, experiencing colonization in the early 17th century and industrial development in the late 18th and early 20th centuries. Environmental degradation due to increasing population and lack of infrastructure maintenance was eventually improved through contaminant control and sewage treatment starting in the 1970s. Benthic macroinvertebrate community structures responded to these environmental changes, showing patterns corresponding to stressors and management actions in the watershed.

Summary: The Zhujiang River Estuary is experiencing eutrophication due to anthropogenic activities. Nutrient dynamics and fluxes to the Lingdingyang water through four outlets were investigated. Riverine fluxes of dissolved inorganic nitrogen (DIN) and dissolved silicate (DSi) varied seasonally, with the highest in spring and the lowest in winter. Riverine flux of phosphate showed little seasonal variability. Most riverine nutrients entered Lingdingyang water through Humen Outlet. Estuarine export fluxes of DIN were higher than riverine flux in May, potentially due to local sewage, while they were lower in August. Export fluxes of phosphate were higher than riverine flux in May and August. Large amounts of DSi were buried in the estuary in May and August. Despite excess DIN input, eutrophication effect was not severe due to light limitation.

Summary: Urban agglomeration has become the main regional unit to cope with global challenges. However, with the development of economic globalization and urbanization, urban agglomeration is facing increasing pressure on nature resources and ecological environment. The study on the Fujian Delta Urban Agglomeration in China reveals that it is a consumption-orientated economic system dominated by non-renewable resource input, with moderately uncoordinated regional social-economic and resource-environment systems. Cross-regional cooperation is important for achieving sustainable development and a win-win situation between cities.

Summary: Soil erosion is a severe environmental problem in China, and soil and water conservation measures have played a crucial role in reducing streamflow and sediment yields. This study quantitatively explored the hydrological effects of these measures in the Tingjiang River Watershed, using a nested watershed approach and various statistical analyses. The results showed a significant downward trend in annual streamflow and sediment yields since the implementation of soil and water conservation measures, indicating their significant impact. Precipitation had a larger influence on streamflow than the conservation measures, but the contribution of the measures to sediment yields gradually dominated in the watershed. The establishment of an ecological threshold at 10% afforestation area revealed remarkable improvements in hydrological effects.

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.
