“…de Andrade et al. (2021) assessed the temporal and spatial variability of phosphorus FFs for freshwater in Bahia, Brazil, and concluded that FFs do not intensely vary monthly, although they recommended distinguishing two periods of higher and lower water availability. In contrast, their analysis suggests that FFs are highly site dependent, thus it is important to regionalize eutrophication indicators.…”

Excessive nitrogen (N) use in agriculture, industry, and household waste leads to widespread N release throughout the environment, causing eutrophication in both freshwater and coastal areas. To better understand N-induced eutrophication and other N-use-related environmental impacts at the local scale, improvements in the spatial resolution of life cycle impact assessment measures are required. Here, we present a method to estimate gridded fate factors (FFs) at a half-degree resolution based on the Integrated Model to Assess the Global Environment-Global Nutrient Model to provide eutrophication indicators for global N-related manufacture, trade, and consumption in life cycle assessment. Across global freshwater systems, our cumulative FFs have a 5th percentile of 0.9 days and a 95th percentile of 184.0 days. Aggregated FFs for administrative units range from 0.3 days to 211.9 days. The hotspots of cumulative FFs are mainly distributed upstream of large reservoirs or lakes. On a global level, advection is the dominant process controlling the FF (69.7% of areas), followed by retention (29.0%), and water consumption (1.3%). N retention dominates in advectionfavoring, high-discharge regions due to the high residence times, while water consumption tends to dominate water-scarce zones. The results demonstrate the importance of gridded information to assess eutrophication impacts, as it characterizes N emissions from anthropogenic sources at high spatial resolution in comparison to basin-or country-level assessments. Introducing soil-freshwater N fate complements existing P-related fates to improve global assessments of eutrophication.

“…According to the previous reports 3 , the inhibiting effect of chlorides can be eliminated by addition of phosphate ions to the solution. Although phosphates can overcome the scavenging effect of chlorides, their use is problematic because they significantly contribute to eutrophication of natural waters 4 . For this reason, development of new heterogeneous catalysts that would be easier to separate from the reaction mixture after the ozonation process, has attracted particular attention in terms of water and wastewater purification.…”

The degradation of organics through ozonation is strongly reduced by chloride ions. Although the efficiency of such processes can be recovered in the presence of homogeneous phosphates, the addition of these chemicals to water is problematic because of the generation of secondary wastes. Phosphates are known as one of the most important biogens responsible for the eutrophication of rivers and lakes. Thus, their worldwide application should be limited. The main goal of this work was to characterize the performance of solid-state cerium(III) phosphate (CePO4), cerium dioxide (CeO2), and bifunctional CePO4/CeO2 nanocomposite as substitutes for homogeneous phosphates during the ozonation of benzoic acid (BA) in the presence of chlorides. All solid-state samples used in this study were synthesized by facile hydrothermal method and thoroughly characterized. It was documented that heterogeneous CePO4 showed significantly better ozonation recovery effect than homogeneous phosphates. It was also established that the process efficiency could be further enhanced by using the bifunctional nanocomposite. Tests with the use of tert-butanol as a hydroxyl radical scavenger revealed that the improved ozonation efficiency in the presence of CePO4/CeO2 resulted from the action of HO• radicals which were the key reactive oxygen species responsible for the recovery of BA degradation in the presence of chlorides.

“…Fate modeling, which links human activities, P emissions, and P transport in environmental compartments, − is crucial for assessing the contribution of anthropogenic emissions to eutrophication . Existing studies ,, typically use the eight-direction (D8) algorithm based on the Digital Elevation Model (DEM) to trace the environmental fate paths of emissions from various sources.…”
