The present study investigated the use of a biosorbent produced from Leucaena leucocephala pods for the removal of metformin from aqueous solutions. The pods were subjected to chemical and thermal treatments and were referred to as L. leucocephala modified, which was characterized using scanning electron microscopy (SEM). The parameters investigated in the sorption process were temperature, contact time, adsorbent dosage, pH, and initial metformin concentration. The experimental data were in accordance with the Langmuir isothermal model. The maximum adsorption capacity reached was 56.18 mg g−1 at 313 K. In the kinetic study, stability was achieved in 300 min, with 53.24% removal, and the pseudo-first-order model agreed well with the experimental data. The thermodynamic parameters indicated a spontaneous, favorable, and exothermic reaction. The presence of NaCl, CaCl2, and MgCl2 negatively affected metformin adsorption. Thus, the importance of the study was that a developed material showed promising results in the removal of metformin, particularly because it is an innovative material, and there are no studies in the literature on drug removal using L. leucocephala.

Temporal evaluation of the Beni Haroun dam's (Algeria) raw water quality, through a literature review
Authors: Abdesselem Kabour , Lynda Chebbah
Published: July 2023

Several authors have carried out physic-chemical analyses of the raw water from the Beni Haroun dam since it was exploited, and others continue to do so. The aim of this work is to present a temporal synthesis (2003-2018) of the variation in their quality. It depends on several parameters, such as climate, socio-economic development and population growth around its tributaries. The parameters studied are : Temperature, pH, EC, TDS, and in (mg/l) Ca2+ , Mg2+ ,Na+ , K+ , Cl- , SO42- , HCO3- , NO3- , NO2- ,NH4+ and PO43- ,as well as organic parameters such as: COD, BOD5 , dissolved O2 and certain heavy metals (μg/l): Pb, Cd, Zn, Fe, Cr, Cu and Mn.
The results of this collection of publications show that the quality of the raw water from the Beni Haroun dam varies over time, depending on the season and mainly on the water supply resulting from rainfall, which leads to dilution of the various chemical elements. The air temperature modifies the water temperature, which affects the organic composition. The conclusion shared by all the authors is that raw water must undergo prior treatment before being used for drinking or irrigation.

Published: July 2023

Personality traits can have a significant impact on the academic performance and personal growth of students. Certain personality traits, such as conscientiousness, openness, and emotional stability, are associated with higher academic achievement, while others, such as neuroticism and impulsivity, are associated with lower academic achievement. This paper explores the importance of addressing personality traits in students and encouraging self-awareness of their strengths and weaknesses. Therefore, this study explores the importance to better understand the relationship between different personality traits and its impact towards student’s overall performance. The data was collection from 200 students of UiTM Kedah and the data was analysed using Statistical Package for the Social Science (SPSS) version 26.0. The findings reveals some traits were significantly impacting the performance of the university students. By developing strategies for personal growth and self-improvement, students can increase their confidence, resilience, and adaptability in all areas of their lives. The paper concludes that understanding and addressing personality issues in students is crucial in supporting their academic and personal success.

Published: July 2023

As the population grows, natural resources are overly consumed by activities such as deforestation, logging, fisheries, and mining, which are done to supply the world’s demand. Hence, the purchasing of green products is crucial in reducing environmental degradation. Green purchasing behaviour can be referred as to the individual’s purchasing behaviour of environmental-friendly products or products that will not inflict harm nor pollute or deplete the earth’s natural resources, and products that are able to be conserved or recycled. It is a vital part of ensuring sustainable Development Goals (SDGs) is possible, which aim to minimize harmful environmental and health impacts through the promotion of an eco-friendly way of living. Social media in its existence has held a great influence on the consumer in terms of the purchasing process of not just being limited to green products. The use of social media as a marketing or promoting platform for green products holds great advantages in targeting a larger audience to promote these green products. This study was conducted to propose a new framework to assess the influence of social media on consumer intention behaviour in purchasing green products. The proposed model was developed by extending the Theory of Planned Behaviour with social media usage and social media marketing into the model to determine significant factors that influence consumer intention behaviour in purchasing green product.

Published: July 2023

Objective: The objective of this study is to determine and compare the sensitivity and specicity of serum procalcitonin, sepsis index, and immature granulocyte percentage for the early diagnosis of sepsis in CKD patients. Material and Methods: 50 patients of CKD with suspected sepsis were taken and divided into Group A (sepsis) and Group B (no sepsis) based on SOFA score. Blood samples were drawn from all patients within 24 hours of admission or at the time when clinical suspicion of sepsis was made, for relevant investigations, appropriate Pus/Urine culture, Body uid culture, X-ray, USG and CT scan were done for supportive diagnosis and the suspected source of infection based on clinical suspicion. Results: Procalcitonin had a sensitivity of 68.57%, specicity of 80%, and diagnostic accuracy of 72% for predicting sepsis in CKD patients. Sepsis index had a sensitivity of 74.29%, specicity of 86.67%, PPV of 92.86%, NPV of 59.09% and overall diagnostic accuracy of 78% for the diagnosis of sepsis in CKD patients. Immature granulocyte percent had a sensitivity of 60%, specicity of 66.7% and overall diagnostic accuracy of 62% for the diagnosis of sepsis in CKD patients. The combination of sepsis index and procalcitonin for the early diagnosis of sepsis in CKD patients had a sensitivity of 74.3%, specicity of 73.3%, and was found statistically signicant (p=0.008). Conclusion: In our study, we found that the sepsis index was most sensitive (74.29%) and specic (86.67%), and had the highest diagnostic accuracy (78%) among all three markers. Hence Sepsis index can be considered to be a better test vis a vis Procalcitonin for predicting sepsis in CKD patients.

Beyond the “Human Dimension”: Expanding Fink’s taxonomy of significant learning to include the more-than-human world
Authors: Gravett Emily O. , Bach Dorothe
Published: July 2023

We are in a particular moment in human history when climate change and environmental degradation, and the accompanying “eco-anxiety” many of us feel, are challenging predominant ways of living and educating. Just as educational developers have started turning a critical lens inward around other important social justice issues, we all have the opportunity, and indeed a responsibility, to examine the ways that our field may be contributing—albeit inadvertently—to much broader environmental injustices. In this article, we take as our starting point an influential taxonomy of learning, offered by L. Dee Fink, which is frequently utilized in U.S. centers for teaching and learning to guide faculty in the design of their courses. Our purpose is to explore the implications and potential growth areas of one particular area of Fink’s learning taxonomy, what he has called the “Human Dimension,” and then to propose an expanded understanding and application of this dimension to include attention to and relationships with the more-than-human world, which Indigenous peoples have long practiced. We hope, ultimately, for this piece to provoke critical reflection of an anthropocentric approach to education, inspire a broader ecological perspective-taking, and perhaps even result in concrete environmental actions.
Le discours antinobiliaire en Espagne à la fin du XVIIIe et dans la première moitié du XIXe siècle
Authors: Pierre Arnaud
Published: July 2023

Depuis au moins la fin du XVIIIe siècle, il existait en Espagne un courant d’opinion qui, s’il ne remettait pas en cause l’existence même de la noblesse, était très critique envers certains hidalgos, présentés comme oisifs, pauvres et inutiles à la société. Dans la première moitié du XIXe siècle, ce discours critique s’élargit à une dénonciation parfois virulente de « l’aristocratie », l’élite de l’ordre, assimilable aux détenteurs d’un titre de noblesse (titre de Castille). Si la critique n’est pas surprenante de la part des libéraux progressistes, elle l’est plus de la part des libéraux modérés ou de positionnements plus conservateurs. Ce travail, qui se veut une contribution à l’Histoire des cultures politiques espagnoles du premier XIXe siècle, présente le discours hostile à la noblesse durant cette période. Il s’agira de voir comment ce discours majoritaire orienta le libéralisme espagnol au moment où ses défenseurs organisaient la société issue de la révolution.
Ruiz Zorrilla y El Motín: la construcción de una legitimidad revolucionaria en la prensa satírica republicana durante la Restauración (1881-1895)
Authors: Higueras Castañeda Eduardo
Published: July 2023

Manuel Ruiz Zorrilla fue una de las principales referencias del movimiento republicano español en el último cuarto del siglo XIX. Tras ser desterrado en 1875, convirtió su prolongado exilio en la base de la imagen pública que trató de proyectar. En diálogo con la prensa y otros medios de comunicación, construyó un personaje que simbolizaba valores políticos relacionados con la virtud cívica y la masculinidad, como el sacrificio, la integridad, la determinación y la rebeldía. Estos valores, en el discurso del republicanismo radical, se sintetizaban en la idea de revolución. En este sentido, la prensa ilustrada jugó un papel esencial al concretar gráficamente estas ideas y difundirlas a gran escala, en un contexto de tránsito hacia la sociedad de masas. El objetivo de este artículo consiste en analizar cómo los medios satíricos republicanos, con especial atención a la revista ilustrada El Motín, definieron la imagen Ruiz Zorrilla asociada a la legitimidad de la revolución republicana frente a una monarquía que representaba la reacción.
La représentation du genre au XIXe siècle. Masculinités dans le couple royal et la biographie de François d’Assise de Bourbon
Authors: Colás Loricera Félix
Published: July 2023

Le couple royal formé par Isabelle II et François d’Assise est particulièrement intéressant en raison des dynamiques externes et internes qui, sous bien des aspects, ont marqué le devenir de la monarchie et de la société espagnoles. La dynamique interne est définie par « l’inversion » des rôles représentée par le fait qu’Isabelle est la monarque et François le consort, ainsi que par leurs personnalités contrastées. Isabelle a été largement étudiée sous cette perspective, tandis que François représente une étude de cas moins abordée mais tout aussi pertinente. En ce qui concerne les questions externes, la biographie de François d’Assise dans le contexte de son couple est marquée par la période de transition dans les notions de genre du XIXe siècle ainsi que par le passage d’une société traditionnelle-aristocratique à une société victorienne-bourgeoise ; une transition au cours de laquelle le couple est jugé par plusieurs strates de la société et à partir de différents points de vue et canons de comportement.
Labor Demand Forecasting: The Case of Cambodia
Authors: Sereyvuth KY
Published: July 2023

Abstract

Labor demand forecasting is crucial for Cambodia’s economic prosperity. This is because it enables the country to make well-informed decisions and implement effective policies that align with the changing dynamics of its labor market to promote sustainable economic progress. This study utilizes a demand-driven model; specifically, the autoregressive integrated moving average (ARIMA) model with a top-down approach to forecast Cambodia’s labor demand from 2020 to 2025. By capturing current and future labor market trends, we can identify skill requirements and ensure high employment rates for sustainable development. With labor demand forecasting, Cambodia can proactively address skill gaps, optimize workforce planning, and foster an environment conducive to economic growth and stability.

Authors: Nurtjahja Kiki , Unk Sartini , Silitonga Greaceuli
Published: July 2023

The aim of the paper is to observe aflatoxin contamination and toxigenicity of Aspergillus flavus in relation to soil at plantations and coffee beans during drying and storage at smallholder plantations in Berastagi, Karo Regency, North Sumatra. Serial dilution and a direct plating method were used to determine the fungal population and the percentage of beans infected by fungal species. Toxigenicity of A. flavus was tested using a culture method and thin-layer chromatography. The results showed a total of 18 species of fungi were isolated from the soil plantation. Aspergillus niger was the most dominant (log 3.69 cfu/g), followed by A. flavus (log 3.47 cfu/g) and A. tamarii (log 3.43 cfu/g). Cladosporium cladosporioides, Rhizopus stolonifer, and Mucor sp. contaminated the coffee beans during drying, while Aspergillus chevalieri, A. niger, A. repens, A. terreus, and Penicillium citrinum contaminated the beans during storage. The highest percentage (15%) of beans contaminated during drying was caused by R. stolonifer and Mucor sp., whereas during storage, A. niger (15.5%) was the dominant contaminant, followed by A. flavus (14%). A total of eleven A. flavus strains were isolated, consisting of three strains from the plantation, seven strains from coffee beans during drying, and one strain from storage. Based on toxigenicity, 10 strains of A. flavus were aflatoxin producers, with three strains isolated from the soil, six strains isolated from coffee beans during drying, and one strain isolated during storage

На основе имеющихся наблюдательных данных об оптических свойствах шаровой молнии и решения интегрального уравнения Абеля получены возможные радиальные распределения показателя преломления, концентрации заряженных частиц и температуры. Правильность предлагаемого подхода проверена в исследовании рефракции света при прохождении через сферический фронт пропановоздушного пламени. Методом цифровой фотометрии проведены сравнительные расчеты температурных полей в пламени, шаровой молнии и «однокомпонентном плазмоиде».

this study proposes an optical method for studying the structure of short-lived, non-stationary low-temperature plasmoids using the refractive properties of the plasma. We obtained possible radial distributions of the refractive index, concentration of charged particles, and temperature from the available observations of the ball lightning optical properties and the solution of the Abel integral equation. We verified the proposed method by measuring the refraction of light passing through the spherical front of a propane-air flame. The temperature fields in the flame, ball lightning, and “one-component plasmoid” were compared with digital photometry.

Abstract. High-resolution simulations were performed to assess the impact of different parameterization schemes, surface datasets, and analysis nudging on lower-tropospheric conditions near Lake Michigan. Simulations were performed where climatological or coarse-resolution surface datasets were replaced by high-resolution, real-time datasets depicting the lake surface
temperatures (SSTs), green vegetation fraction (GVF), and soil moisture and
temperature (SOIL). Comparison of two baseline simulations employing
different parameterization schemes (referred to as AP-XM and YNT, respectively) showed that the AP-XM simulation produced more accurate analyses on the outermost 12 km resolution domain but that the YNT simulation was superior for higher-resolution nests. The diurnal evolution of the surface energy fluxes was similar in both simulations on the 12 km grid but differed greatly on the 1.3 km grid where the AP-XM simulation had a much smaller sensible heat flux during the daytime and a physically unrealistic ground heat flux. Switching to the YNT configuration led to more accurate 2 m temperature and 2 m water vapor mixing ratio analyses on the 1.3 km grid. Additional improvements occurred when satellite-derived surface datasets were incorporated into the modeling platform, with the SOIL dataset having the largest positive impact on temperature and water vapor. The GVF and SST datasets also produced more accurate temperature and water vapor analyses but had degradations in wind speed, especially when using the GVF dataset. The most accurate simulations were obtained when using the high-resolution SST and SOIL datasets and analysis nudging above 2 km a.g.l. (above ground level). These results demonstrate the value of using high-resolution satellite-derived surface datasets in model simulations.
Maximum respiration rates in hyporheic zone sediments are primarily constrained by organic carbon concentration and secondarily by organic matter chemistry
Authors: Stegen James C. , Garayburu-Caruso Vanessa A. , Danczak Robert E. , Goldman Amy E. , Renteria Lupita , Torgeson Joshua M. , Hager Jacqueline
Published: July 2023

Abstract. River corridors are fundamental components of the Earth system, and their biogeochemistry can be heavily influenced by processes in subsurface zones
immediately below the riverbed, referred to as the hyporheic zone. Within the hyporheic zone, organic matter (OM) fuels microbial respiration, and
OM chemistry heavily influences aerobic and anaerobic biogeochemical processes. The link between OM chemistry and respiration has been hypothesized
to be mediated by OM molecular diversity, whereby respiration is predicted to decrease with increasing diversity. Here we test the specific
prediction that aerobic respiration rates will decrease with increases in the number of unique organic molecules (i.e., OM molecular richness, as a
measure of diversity). We use publicly available data across the United States from crowdsourced samples taken by the Worldwide Hydrobiogeochemical
Observation Network for Dynamic River Systems (WHONDRS) consortium. Our continental-scale analyses rejected the hypothesis of a direct limitation of
respiration by OM molecular richness. In turn, we found that organic carbon (OC) concentration imposes a primary constraint over hyporheic zone
respiration, with additional potential influences of OM richness. We specifically observed respiration rates to decrease nonlinearly with the ratio
of OM richness to OC concentration. This relationship took the form of a constraint space with respiration rates in most systems falling below the
constraint boundary. A similar, but slightly weaker, constraint boundary was observed when relating respiration rate to the inverse of
OC concentration. These results indicate that maximum respiration rates may be governed primarily by OC concentration, with secondary influences
from OM richness. Our results also show that other variables often suppress respiration rates below the maximum associated with the
richness-to-concentration ratio. An important focus of future research will identify physical (e.g., sediment grain size), chemical (e.g., nutrient
concentrations), and/or biological (e.g., microbial biomass) factors that suppress hyporheic zone respiration below the constraint boundaries
observed here.
Improved catalog of NOx point source emissions (version 2)
Authors: Beirle Steffen , Borger Christian , Jost Adrian , Wagner Thomas
Published: July 2023

Abstract. We present an updated (v2) catalog of NOx emissions from point sources as derived from TROPOspheric Monitoring Instrument (TROPOMI) measurements of NO2 (Products Algorithm Laboratory (PAL) product) combined with wind fields from ERA5.
Compared to version 1 of the catalog (Beirle et al., 2021), several improvements have been introduced to the algorithm. Most importantly, several corrections are applied, accounting for the effects of plume height on satellite sensitivity, 3D topographic effects, and the chemical loss of NOx,
resulting in considerably higher and more accurate NOx emissions.
In addition, error estimates are provided for each point source, taking into account the uncertainties of the individual retrieval steps. The v2 catalog is based on a fully automated iterative detection algorithm of point sources worldwide.
It lists 1139 locations that have been found to be significant NOx sources.
The majority of these locations match power plants listed in the Global Power Plant Database (GPPD).
Other NOx point sources correspond to cement plants, metal smelters, industrial areas, or medium-sized cities. The emissions listed in v2 of the catalog show good agreement (within 20 % on average) to emissions reported by the German Environment Agency (Umweltbundesamt, UBA) as well as the United States Environmental Protection Agency (EPA). The data are publicly available at https://doi.org/10.26050/WDCC/No_xPointEmissionsV2 (Beirle et al., 2023).
Technical note: Complexity–uncertainty curve (c-u-curve) – a method to analyse, classify and compare dynamical systems
Authors: Ehret Uwe , Dey Pankaj
Published: July 2023

Abstract. We propose and provide a proof of concept of a method to analyse, classify
and compare dynamical systems of arbitrary dimensions by the two key features
uncertainty and complexity. It starts by subdividing the system's time trajectory into a number of time slices. For all values in a time
slice, the Shannon information entropy is calculated, measuring within-slice
variability. System uncertainty is then expressed by the mean entropy of all time
slices. We define system complexity as “uncertainty about uncertainty” and express it by the entropy of the entropies of all time slices. Calculating and
plotting uncertainty “u” and complexity “c” for many different numbers of time
slices yields the c-u-curve. Systems can be analysed, compared and classified by the
c-u-curve in terms of (i) its overall shape, (ii) mean and maximum
uncertainty, (iii) mean and maximum complexity and (iv) characteristic
timescale expressed by the width of the time slice for which maximum
complexity occurs. We demonstrate the method with the example of both
synthetic and real-world time series (constant, random noise, Lorenz
attractor, precipitation and streamflow) and show that the shape and
properties of the respective c-u-curve clearly reflect the particular
characteristics of each time series. For the hydrological time series, we
also show that the c-u-curve characteristics are in accordance with
hydrological system understanding. We conclude that the c-u-curve method can
be used to analyse, classify and compare dynamical systems. In particular,
it can be used to classify hydrological systems into similar groups, a
pre-condition for regionalization, and it can be used as a diagnostic measure
and as an objective function in hydrological model calibration. Distinctive features of the method are (i) that it is based on
unit-free probabilities, thus permitting application to any kind of data,
(ii) that it is bounded, (iii) that it naturally expands from single-variate to
multivariate systems, and (iv) that it is applicable to both deterministic
and probabilistic value representations, permitting e.g. application to
ensemble model predictions.

Published: July 2023

The “No Fixed Address” version 2 (NFAv.2) project tested the efficacy of a potential best practice program that aimed to prevent discharge from hospital into homelessness. Forchuk and colleagues developed a system that streamlined housing and social supports using on-site access to help inpatients in a psychiatric unit who were homeless or at-risk of homelessness find safe, affordable housing. A total of 370 individuals accessed the NFAv.2 program between August 2017 and May 2020. Of these, 88 participants who accessed the intervention were enrolled in the evaluation of the project. Information on housing history and housing outcomes were collected during hospital admission and at 3-time points post-discharge. Focus groups were conducted for program participants, health care staff, and community partners to gather information regarding their experiences with the program. Of those who participated in the intervention, 80% were housed and remained housed at 12 months post-discharge. Results from focus groups also indicated that the majority of NFAv.2 clients, staff, and community partners were satisfied with the intervention. Since homelessness has a detrimental effect on recovery, client safety, and healthcare expenditures, locating safe housing has had a positive impact on treatment, rehabilitation, and the healthcare system as a whole. The findings of this project offer policy alternatives for the prevention of homelessness for at-risk individuals.

Определение уровня кровяного давления (КД) неинвазивным способом и без манжеты сфигмоманометра имеет большую актуальность при проведении непрерывного мониторинга или скрининговых исследованиях. В данной работе представлена концепция построения и описание опытного образца нового измерительного устройства для оценки параметров КД по данным сигналов фотоплетизмограммы и электрокардиограммы. Для определения параметров КД используются предобученные модели машинного обучения. Устройство реализовано в виде электронного блока сбора данных и программного обеспечения для расчета параметров КД на стороне персонального компьютера. Электронный блок выполнен в виде микроконтроллерной системы, в котором снижение влияния помех при регистрации сигналов достигается за счет использования беспроводного канала связи с компьютером. Разработанное программное обеспечение имеет графический интерфейс пользователя, реализует задачи фильтрации и анализа сигналов, извлечения информативных признаков, прогнозирования систолического и диастолического уровней КД и хранения информации. Разработанное устройство может быть эффективно использовано для контроля над распространением гипертонии среди населения за счет более простой процедуры проведения измерений на базе устройств носимой электроники.

Water-DMSO Co–Solvent effect and kinetics of acid catalyzed Hydrolysis of butyl formate and Influence on Activation Parameters
Authors: Singh A. K.
Published: July 2023

The acid catalyzed hydrolysis of butyl formate in presence of 0.1N-HCI in water and the presence of water-DMSO mixture containing up to 30-70% (v/v) was studied over the temperature ranging from 20-400C. The rate of reaction decreases with decrease of water content of the solvent mixture and reached minima at about 70% of organic solvent. The number of water molecule associated with activated complex was showing decrease in trend with increase of temperature, is an indication of change in mechanism from unimolecular to bimolecular in reaction media. The parameters of thermodynamic activation were also calculated and discussed in terms of solvent effect with help of plots of ΔH* versus ΔS*, the isokinetic temperature was calculated and found to be greater than 300.

Workplace integration of undergraduate student nurses through clinical placement remains an integral part of nurse education. The role of clinical facilitators who support this integration is complex and shaped by the expectations of various key stakeholders. These multiple expectations often resulting in the role being blurred and lacking clarity. The research aim is to identify the roles and expectations of clinical facilitators from the perspectives of academics/educators and students and to explore qualities that allow clinical facilitators to conduct their role effectively. A cross-sectional survey was utilised. Exploratory factor analysis, free text data and comparative analysis were used. Findings suggest a discordance in understanding of the clinical facilitator role by educators and students. Students tended to focus on skills and knowledge without consideration of the broader nursing profession. The clinical facilitator’s ability to role model and influence is seen as a “hidden curriculum” that students are largely unaware of. The clinical facilitator role is complex, with education critical in supporting this role and thus the success of students. Illumination of the hidden nursing curriculum would enable better understanding of the clinical facilitator role in engaging students with the varying requirements of the nursing profession.
Effects of health concept model-based detailed behavioral care on mood and quality of life in elderly patients with chronic heart failure

A condition of exposure to multiple stressors resulting in a mixed clinical picture spanning conventional categories without meeting any of them in full, encompasses a risk for a list of comorbidities preventing appropriate prevention and treatment. New transformative transdiagnostic approaches suggest changes spanning conventional categories. They base their systems of classification on biomarkers as well as on brain structural and functional dysregulation as associated with behavioral and emotional symptoms. These new approaches received critiques for not being specific enough and for suggesting a few biomarkers for psychopathology as a whole. Therefore, they put the value of differential diagnosis at risk of avoiding appropriate derived prevention and treatment. Multiplicity of stressors has been considered mostly during and following catastrophes, without considering the resulting mixed clinical picture and life event concomitant stressors. We herewith suggest a new category within the conventional classification systems: The Complex Stress Reaction Syndrome, for a condition of multiplicity of stressors, which showed a mixed clinical picture for daily life in the post coronavirus disease 2019 era, in the general population. We argue that this condition may be relevant to daily, regular life, across the lifespan, and beyond conditions of catastrophes. We further argue that this condition may worsen without professional care and it may develop into a severe mental health disorder, more costly to health systems and the suffering individuals. Means for derived prevention and treatment are discussed.

Published: July 2023

This study investigated the impact of high-density septic systems (aka Onsite Sewerage and Disposal Systems, OSTDS) along the canals located in the communities of the lower Taylor Creek area on water quality at the northern periphery of Lake Okeechobee. Using sucralose as an anthropogenic tracer, we investigated the septic derived non-point sourcing of nutrients which feed harmful algal (cyanobacterial) blooms (HABs) in Lake Okeechobee and adjacent waters.

The subdivisions investigated were Treasure Island (TI) and Taylor Creek Isles (TCI) located to the east and west of Taylor Creek. TI homes are all on septic tanks whereas TCI is serviced by a municipal vacuum sewerage system.

TI canals had 5.3 times the mean concentration of sucralose relative to TCI canals. On a yearly basis, the Treasure Island sites away from Taylor Creek had 2.25 times the total phosphorus and 1.20 times the total nitrogen compared to the Taylor Creek isles sites. An extensive literature review of non-point pollution is included.
