Summary: This study proposes a computational framework to quantify the economic impacts of harmful algae blooms (HABs) caused by nutrient pollution from livestock waste. Through a case study in the Upper Yahara watershed region in Wisconsin, USA, it is demonstrated that every excess kilogram of phosphorus runoff from livestock waste results in total economic losses of 74.5 USD. Coordinated market analysis shows that this economic impact can activate a nutrient management and valorization market to help balance phosphorus within the study area. The proposed framework can assist regulatory agencies in developing policies to mitigate the impacts of nutrient pollution.

Summary: The study utilized sediment core nutrient concentrations and stable isotope analysis to reveal information about past and current nutrient loads and sources in different parts of the Derwent estuary in Tasmania, Australia. Riverine inputs and pulp and paper mill effluent were found to influence the upper estuary, while the middle estuary had higher nutrient concentrations compared to other Australian estuaries. There was a transition from terrestrial organic matter in the upper estuary to marine organic matter in the middle/lower estuary, with a clear influence from a nitrogen source likely to be wastewater treatment plant effluent.

Summary: In this study, multiple stable isotopes (nitrogen, hydrogen, and dissolved inorganic carbon) were used along with phosphate oxygen isotopes to trace phosphorus sources. The SIAR and IsoSource models were used to estimate the contributions of potential sources. The results showed that phosphate oxygen isotopes can be used to trace phosphorus sources, and other stable isotopes can assist in identifying the main sources. The SIAR model had lower uncertainty in the calculation results compared to the IsoSource model. These findings have significant implications for tracing phosphorus sources using multiple stable isotopes.

Summary: Lake water eutrophication is a major obstacle to sustainable economic development in China. Studies on the effects of mainstream currents on reservoirs have been relatively scarce, although changes in water-sediment transport regime in downstream rivers may influence nutrient transport in connected lakes. This study focused on Sanshiliujiao Lake in Fujian, China and aimed to estimate the phosphorus and nitrogen loads to the lake, explore their sources, and assess their ecological effects. The study found that water diversion and non-point sources were the main contributors to the total phosphorus and total nitrogen loads, and water diversion also affected the structure and abundance of phytoplankton communities.

Summary: The study finds significant variation in the methods used by European countries to set river nutrient thresholds, with some countries relying on expert judgement or statistical distribution, while others prefer statistical relationships based on biological variables. For the first time, an ecology-based approach is used to derive nutrient thresholds for various river types in Central Europe. The results demonstrate that adopting ecology-based nutrient targets could improve sustainable river management where nutrients are the main pressure preventing the achievement of good ecological status.

Summary: Phosphorus (P) released from sediment can increase the concentrations of dissolved P in water, leading to algal blooms. Identifying the sources of sediment P is crucial for managing P and restoring eutrophic aquatic ecosystems. This study used chemical sequential extraction and oxygen isotopic compositions to identify the source of inorganic P in Lake Dianchi sediments. The results revealed complex transformation processes of different P fractions in sediments and provided insights into the source and biogeochemical cycling of P in eutrophic lakes.

Summary: Freshwater lakes across the world have undergone significant changes in biological components and water quality. Previous studies focused on nutrient enrichment as the main driver, but the relative importance of climate change and fish stocking on water quality is not well understood. By analyzing data from 155 lakes in subtropical China, the study found no significant changes in water total nitrogen and total phosphorus over the past two decades. However, phytoplankton abundance increased significantly, and water clarity declined by 44.1%. Carp stocking and climate change were identified as potentially more important drivers of water quality change than nutrients.

Summary: This study traced the speciation and isotopic composition of Zn in the sediments of a freshwater lake that underwent strong eutrophication for one hundred years, in order to assess the potential use of sedimentary Zn isotopes in recording such environmental disturbances. The results showed that the sedimentary Zn isotope signal varied as the lake transitioned from pre-eutrophic to eutrophic conditions. A change in Zn speciation from clay minerals to ZnS was observed, along with a depletion of light Zn in the eutrophic sediments. This is attributed to enhanced biological uptake of light Zn in the water column and subsequent transformation into ZnS during early diagenesis. The study highlights the potential of sedimentary Zn isotopes as indicators of past eutrophic periods in freshwater lakes and their ability to provide insights into paleo-environmental conditions and land use.

Summary: The study shows that the decline in scleractinian coral cover and the increase in macroalgal blooms on the Belize Barrier Reef are mainly attributed to land-based nutrient pollution. Analysis indicates that nutrients in macroalgae primarily come from land, with delta N-15 values matching those of human sewage, suggesting that nitrogen enrichment has increased phosphorus limitation, driving macroalgal blooms and impacting coral on the BBR.

Summary: Legislation and interest are in place to protect freshwater and marine ecosystems from the environmental impact of aquaculture. However, eutrophication caused by aquaculture remains a significant concern. Phosphorus concentration increases in adjacent waters due to soluble phosphorus, uneaten feed, feces, and metabolic waste from farmed fish. The dietary phosphorus retention in farmed fish is influenced by intestinal enzymes, transporters, regulating factors, intestinal morphology, and the gut microbiome. In order to reduce phosphorus pollution and make aquaculture more sustainable, it is necessary to understand the processes affecting nutrient retention and absorption, as well as the impact of dietary factors, anti-nutritional substances, and intestinal morphology. Optimizing feed composition, managing gut health, and treating effluent aquaculture waters can help reduce the environmental impact of aquaculture.

Summary: The presence of Chinook salmon in streams in southern Chile has significantly enhanced the growth of biofilm-associated algae, leading to increased biomass. The incorporation of marine-derived nutrients by algae only occurred in streams with lower water flow in one of the two studied spawning seasons, suggesting that inter-annual variation in discharge can mediate the subsidising effect of salmon.

Summary: Excessive nutrient concentrations in fresh waters are a global problem, and further research has found that freshwater abstractions from surface waters and groundwaters, as well as watermains leakage, contribute to significant nitrate-N fluxes. In the United States, freshwater abstraction retains 417 kt NO3-N/yr, and watermains leakage returns 7 kt NO3-N/yr back to the environment. There are large regional variations in these fluxes, with higher fluxes typically found in the eastern regions. These findings are important for policymakers and water resource managers in better managing the impact of nitrogen in the environment and should be included in national and global nitrogen budgets.

Summary: Human activity has led to excessive phosphorus levels and eutrophication in US coastal and freshwater areas. Understanding phosphorus sources is crucial for effective management. Public water systems use phosphate to control corrosion, adding 4-14.9 kt PO4-P yr(-1) to the US water distribution network in 2015. Leakage and outdoor water use resulted in the loss of 0.7-2.6 kt PO4-P yr(-1), with 9.3 kt PO4-P yr(-1) being returned to wastewater treatment plants, accounting for 2.7% of the national influent P load.

Summary: The isotopic data of nitrate in global rivers and shallow aquifers reveal differences in nitrate concentrations and nitrogen isotope composition between the two water bodies. Water temperature plays a role in affecting the isotopic composition of nitrate, with waste-related nitrogen source signals being more prominent in colder seasons. Isotopic assays are crucial for understanding nitrate pollution and informing effective agricultural and land management strategies.

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.
