Diisopropylamine (DIPA), aminomethyl propanol (AMP), amino ethoxy ethanol (AEE), diethanolamine (DEA), ethanolamine (EA), pyridine (PYR) and methyl diethanolamine (MDEA) are used for carbon capture and to sweeten sour gas, and are found in groundwater. They are also used in cosmetic products. Taurine is abundant in the body, with key biological functions linked to its charged SO groups. Interactions between SO and amines have not been studied, but can strongly affect the biological function of taurine. Fourier transform infrared spectroscopy indicates SO…HN hydrogen bonding between taurine and DIPA, AMP, AEE, DEA, EA and MDEA. These interactions induce the formation of hydrophobic amine-taurine clusters, thus decreasing amine miscibility in water, as revealed by light scattering. This effect is most marked for DIPA, leading to turbid mixtures indicative of micron-sized droplets. PYR and taurine likely interact via S…N bonding. This study offers insights regarding potential mechanisms of amine toxicity to humans.

This study evaluates flood susceptibility and risk on Bulk Supply Points in the Greater Accra region (GAR) using a Frequency Ratio model based on 15 flood conditioning factors. The model explores the influence of natural, meteorological and anthropogenic factors on flooding occurrences under the Shared Socioeconomic Pathway (SSP) scenarios and assesses flood risks at Bulk Supply Points (BSPs). Flood susceptibility mapping was conducted for both current and future periods under various SSP scenarios. Results reveal that elevation, slope, soil type, distance from urban areas, and SPI are the most influential factors contributing to flooding susceptibility in the region. The current flood map, about 37% of the total area of GAR categorized under the moderate flood-susceptible zone category followed by about 30% categorized under the low flood-vulnerable zone. However, about 16% was categorized under the very high flood-vulnerable zone. The study projects increasing flood susceptibility under the SSP scenarios with intensification under SSP2 and SSP3 scenarios. For instance, the areas categorized as high and very high flood susceptibility zones are projected to expand to approximately 32% and 26% each by 2055 under SSP3. The study also assesses flood risks at Bulk Supply Points (BSPs), highlighting the escalating susceptibility of power assets to flooding under different scenarios. For instance, in the very high scenario, flooding is estimated to reach 640 h in 2045 and exceed 800 h in 2055-more than double the 2020 baseline. The analysis shows the bulk supply points face increasing flood susceptibility, with risks escalating most sharply under the severe climate change SSP3 and SSP5 scenarios. Over 75% of BSPs are expected to fall in the low- to medium-risk categories across SSPs while more than 50% of BSPs are within medium- to high-risk categories in all scenarios except SSP1, reflecting the impact of climate change. SSP3 and SSP5 stand out with over 60% of BSPs facing high or very high flooding risks by 2055. It indicates moderate resilience with proper adaptation but highlights potential disruptions in critical infrastructure, such as BSPs, during persistent flooding. The findings of the study are expected to inform Ghana's contributions towards addressing Sustainable Development Goals (SDGs) 7, 11 and 13 in Ghana.

Abstract This study assessed the physicochemical and microbiological quality of sachet drinking water samples in Kumasi, a major city in Ghana. Samples were collected from various sources within the city. Physicochemical properties, including pH, total dissolved solids, and concentrations of calcium, sodium, potassium, and magnesium ions, were analyzed following established protocols. Additionally, fluoride concentration was determined. The assessment criteria for water quality were based on the World Health Organization’s and the Ghana Standards Authority’s recommended standards for drinking water. The samples were also subjected to microbial analysis to detect the presence of E. coli and coliforms, and to evaluate microbial quality. The findings indicated that most physicochemical properties of the samples met the World Health Organization’s standards for safe drinking water, except for the slightly acidic pH. Total dissolved solids and the concentrations of calcium, sodium, potassium, fluoride and magnesium ions were within acceptable ranges. Strong positive correlations were observed among various physicochemical parameters of sachet water. However, microbial analysis revealed that 67% of the samples were contaminated with pathogenic microorganisms, including E. coli and coliforms, indicating poor microbiological quality. While sachet water samples generally meet physicochemical safety standards, addressing microbial quality is essential to ensure the safety of drinking water in Kumasi.

Abstract Culvert blockage at the inlet can dramatically alter the local hydraulic characteristics that often increase backwater rise, change the flow patterns, and thereby increase the risk of upstream flooding. The impact of culvert blockage is not usually included in the initial hydraulic design, although it can cause significant losses once the culvert becomes blocked. Culvert hydraulics including backwater rise with respect to blockage slope and ratio has been neglected in the studies conducted so far. In this study, we conducted a series of narrow flume tests to investigate the effects of four bottom blockage slope angles and five blockage ratios on the hydraulic characteristics of box culverts, including backwater rise, and upstream mean velocity at various Froude numbers. The results showed that Froude number, blockage ratio, and slope angle were regarded as the controlling variables for culvert backwater rise. Backwater rise increased dramatically with increasing blockage ratio and Froude number. Compared to blockage ratio B = 0.20, ΔH/h u increased by 2, 5, 9, and 13 times for B = 0.40, 0.60, 0.80, and 1, respectively. However, when the blockage slope angle decreased, the backwater rise reduced and upstream mean velocity increased in compared with vertical blockage. The relative backwater rise reduced from 0.32 to 0.29, when blockage slope angle decreased from 90° to 18.44° at B = 1 and F o = 0.10. In addition, the length and maximum depth of water surface depression inside the culvert itself were larger with increasing blockage ratio and Froude number. For F o = 0.10, d/h o = 0.13 and L/h o = 0.94 for B = 0.20 compared to d/h o = 0.32 and L/h o = 4.34 for B = 1. The results were also combined to develop an equation to predict backwater rise in the range 0.10 ≤ F o ≤ 0.25, 0 ≤ B ≤ 1, and 18.44° ≤ α ≤ 90°. To enhance the accuracy, it is recommended to apply the equation for ΔH/h u ˃ 0.10. It is useful and practical in applications to add the probability of backwater rise or losses owing to culvert blockage within accounting of losses during the hydraulic design of culverts, especially in channels exposed to debris.
进水口涵洞堵塞会极大地改变当地的水力特性，往往会增加回水上升，改变水流形态，从而增加上游洪水发生的风险。涵洞堵塞的影响通常不包括在最初的水力设计中，尽管一旦涵洞堵塞会造成重大损失。涵洞水力学包括回水上升对堵塞坡度和比的影响，在目前的研究中被忽略。在本研究中，我们进行了一系列窄水槽试验，研究了四种底部堵塞坡角和五种堵塞比对箱涵水力特性的影响，包括回水上升和不同弗劳德数下的上游平均流速。结果表明，弗劳德数、堵塞比和坡角是涵洞回水上升的控制变量。随着堵塞比和弗劳德数的增加，回水上升幅度显著增大。与堵塞比B = 0.20相比，当B = 0.40、0.60、0.80和1时ΔH/h u分别提高了2倍、5倍、9倍和13倍。与垂直堵塞相比，当堵塞坡角减小时，回水上升幅度减小，上游平均流速增大。当B = 1, F = 0.10时，堵塞坡角由90°减小至18.44°，相对回水上升由0.32减小至0.29。此外，随着堵塞比和弗劳德数的增加，涵洞内部水面凹陷的长度和最大深度也越大。当F = 0.10时，B = 0.20时d/h o = 0.13, L/h o = 0.94，而B = 1时d/h o = 0.32, L/h o = 4.34。结果还结合起来建立了一个方程，用于预测0.10≤F≤0.25,0≤B≤1和18.44°≤α≤90°范围内的回水上升。为提高计算精度，建议采用ΔH/h u 0.10的公式。在涵洞的水力设计中，特别是在有碎石的沟渠中，在计算涵洞的损失时，加入因涵洞堵塞而引起的回水上升或损失的概率，在实际应用中是有用的。

Abstract In the Northern Dezful-Andimeshk Plain, the primary source of drinking water is groundwater, which has low quality in some places. Thus, groundwater quality in this area needs an accurate evaluation. In this research, the fuzzy and Schoeller deterministic method assessed the Northern Dezful-Andimeshk Plain drinking water, and the results of both methods were used to zone and compare the drinking quality of the plain groundwater in the Arc GIS environment. The deterministic method classifies drinking water quality from good to bad. According to this method, 56.81% of the total area of the plain has good quality, 20.83% of the total area is acceptable, 18.77% of the total area has inappropriate quality, and 3.57% of the total area has bad quality. However, in the fuzzy method, groundwater in 21.6% of the total area of the plain with a confidence percentage of 70% to 81% is desirable, in 75.23% of the total area of the plain with a confidence percentage of 32% to 70% is acceptable, and 3.69% of the total area of the plain with drinking confidence of 20% to 22% is nonacceptable. The results showed that the fuzzy method is better than the Schoeller deterministic method because it reduces uncertainties, increases accuracy in the evaluation, increases flexibility in the threshold limits of water quality parameters, and provides a quantitative and qualitative assessment of drinking water. Also the zoning map obtained from this method is more compatible with environmental and pollution realities. Graphical Abstract

Abstract One approach to addressing energy security issues is to produce renewable and sustainable bioenergy using abundant waste resources through anaerobic co-digestion (AcoD). However, the lignocellulosic nature of these biomass resources makes them recalcitrant, and pretreatment is required to make them more amenable to conversion. Iron oxide nanoparticles (ION) have been shown to increase methane yield significantly when added to biomass resources. This study aimed to investigate the effect of ION application on Sorghum stover (SS) and Winery solid waste (WSW) under mesophilic conditions. Hydrothermal synthesis was used to obtain Fe 3 O 4 nanoparticles. Biomethane potential (BMP) tests were carried out in semi-continuous batch reactors with and without ION singly and combined SS: WSW (1:1) during a 30-day retention period. The results showed that the ION application on WSW delivered a higher biogas yield (380 mL), indicating an increase of 162% in biogas production compared to the sample without ION (145 mL). In addition, CH4 generation went from 30 to 114 mLCH4, indicating a 280% increase. However, adding ION to SS inhibited CH4 production. The study found that ION addition significantly improved biogas yield, especially with WSW, where the increase was more than triple, of interest to bioenergy and waste management practitioners.

However, the lignocellulosic nature of these biomass resources makes them recalcitrant, and pretreatment is required to make them more amenable to conversion. Iron oxide nanoparticles (ION) have been shown to increase methane yield significantly when added to biomass resources.
