Autism spectrum disorders (ASD) arise from a complex interplay between genetic predisposition and various en - vironmental factors, leading to diverse and intricate conditions. Over recent decades, there has been a noticeable increase in autism prevalence. Thus, the main objective of this exploratory investigation is to evaluate the effects of heavy metal poisoning on the metabolic and nutritional profiles of 20 children diagnosed with autism spectrum disorder (ASD) in Morocco. Based on the descriptive statistical methods and the chi-square (χ 2 ) test, we analyzed the results of the study, which involved around 100 biological parameters conducted in the United States (Mosaic Diagnostics) .The results revealed that variations in neurotransmitter production, dysbiosis, yeast overgrowth, elevated oxidative stress, mitochondrial dysfunction, increased oxalate levels, and deficiencies in vitamins and minerals among the children were connected to heavy metal poisoning and intoxication. These findings under - scored the link between metabolic profiles and heavy metal poisoning, highlighting the need for individualized and multidisciplinary care approaches for children with ASD. Further research and controlled clinical trials are necessary to validate these interventions comprehensively.

Acidic water from the coal of mining pool has been polluted from the surrounding coal stockpile stocpile industry. Water quality in mining ponds can threaten the biota in it. During this time, coal mining pool the local community uses water extensively for everyday requirements like drinking, washing, and bathing. More than time it turns out that coal mine acidic water has been polluted. This problem needs to be sought a solution, one of which is required treatment technology for creating water quality that satisfies requirements for drinking water quality. This research tries to use NF270 membrane type Nanofiltration membrane technology to eliminate COD, TSS, TDS, and metal parameters (Fe, Mn). This research was conducted by analyzing the influence pressure (4, 5, and 6 bar) on each component’s rejection rate and flux each parameter. The results of the study show the processed results as follows; Turbidity, Color, COD, TSS, TDS, Fe and Mn at pressures 4, 5, and 6 bar of acid mine rejection water values, namely; Turbidity (96.23%; 98.7%; 100%), Color (79%; 98%; 100%), COD (57.9%; 63.7%; 83.19%), TSS (73, 3%; 87.2%; 95.8%), TDS (62.7%; 66%; 70.19%), Fe (36%; 74.5%; 100%), Mn (100%; 100 %; 100%). Acidic wa - ter treatment in coal mining ponds can be turned into drinking water using nanofiltration membranes producing the best percentage of rejection at pressures of 5 and 6 bar. Water treatment with Nanofiltration membrane technology has produced treated water in accordance with drinking water quality standards required by Priest of Wellbeing Pronouncement of the Republic of Indonesia No. 907/Menkes/Sk/VII/2002 and Clergyman of Climate Pronounce - ment the Decree of the Minister of Environment No. 492 / IV / 2010 / MENKES / PER. NF 270 membrane can remove heavy metals and other impurities in acidic water by more than 90%.

The floods of the Lahdar River cause repeated inundations and damage to road infrastructures, particularly crossing structures in the territorial center of Had Msila. Our study involved the application of various methods to estimate flood flows for different return periods along the Lahdar River. The selected flows were chosen after a comparative analysis of values calculated by the different methods used. These results served as the basis for hydraulic modeling aimed at assessing water levels to establish risk zone mapping. This step is crucial in flood risk assessment. Two main approaches were distinguished: hydrometeorological methods, based on regional parameters derived from rainfall data, and empirical methods, used in the absence or with limited data on flood flows in a given region. Hydraulic modeling was carried out using two software programs: a Geographic Information System (GIS) such as Arc-GIS, and a specific river modeling software like Hec-Ras, allowing for the numerical representation of the natural state of the territory. The results obtained serve as the foundation for all river hydraulic modeling, thereby facilitating flood prediction and hydrological risk management in floodplains. Modeling Lahdar River floods in the studied sections enables the prediction of flood risk and its impacts on constructions and infrastructure in the Had Msila Center.
拉赫达尔河的洪水多次淹没道路基础设施，并对其造成破坏，尤其是 Had Msila 领土中心的过境结构。我们的研究包括采用各种方法估算拉赫达尔河沿岸不同重现期的洪水流量。在对所使用的不同方法计算出的数值进行比较分析后，选择了选定的流量。这些结果是水力模型的基础，旨在评估水位以绘制风险区域图。这一步骤在洪水风险评估中至关重要。主要有两种方法：基于降雨数据得出的区域参数的水文气象方法，以及在缺乏特定区域洪水流量数据或数据有限的情况下使用的经验方法。水力模型的建立使用了两种软件：一种是地理信息系统（GIS）（如 Arc-GIS），另一种是专门的河流模型软件（如 Hec-Ras），后者能够以数字形式表示领土的自然状态。所获得的结果可作为所有河流水力模型的基础，从而促进洪泛区的洪水预测和水文风险管理。对所研究河段的拉赫达尔河洪水进行建模，可以预测洪水风险及其对 Had Msila 中心的建筑和基础设施的影响。

The mangrove ecosystem significantly contributes to nutrient and carbon exchange. It is primarily stored in the soil as organic matter, significantly benefiting the surrounding organisms. However, it could be changed depending on its surrounding conditions. This research aimed to determine the percentage of soil carbon-nitrogen and its ratio in two mangrove ecosystems, one with high anthropogenic impact (Tahura Ngurah Rai) and the other on a small island (Lembongan Island). We collect soil samples on 14 plots at each station at 0–30 cm depth and use carbon titration and TN-Kjeldahl methods for soil carbon-nitrogen measurement. The result shows substantial disparities in soil carbon levels between these ecosystems, but the soil nitrogen content was comparable. Two specific plots at Tahura Ngurah Rai (T8 and T11) were found at low soil carbon levels due to the damage to the mangrove forest. The C/N values vary between stations, primarily because of their different sources (Tahura Ngurah Rai: human activities, Lembongan: marine organisms). The C/N value at Tahura Ngurah Rai is higher than the Redfield ratios, while Lembongan Island is on the contrary. However, its levels at both stations are still categorized as common conditions for mangrove ecosystems compared to various sites in Indonesia. Future research will involve measur - ing radioisotope characteristics to verify the origin of nutrients in these ecosystems. Obtaining measurements of environmental parameters is also necessary to provide a more comprehensive explanation of the results.

The removal of congo red (CR) is a critical issue in contemporary textile industry wastewater treatment. The current study introduces a combined electrochemical process of electrocoagulation (EC) and electro-oxidation (EO) to address the elimination of this dye. Moreover, it discusses the formation of a triple composite of Co, Mn, and Ni oxides by depositing fixed salt ratios (1:1:1) of these oxides in an electrolysis cell at a constant current density of 25 mA/cm 2 . The deposition ended within 3 hours at room temperature. X-ray diffractometer (XRD), field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), and energy dispersive X-ray (EDX) characterized the structural and surface morphology of the multi-oxide sediment. Marvelously, the deposition has simultaneously occurred on both anodic and cathodic graphite electrodes. These electrodes besides aluminum (Al) are employed as anodes in the EC-EO system, and the results were optimized by response surface methodology (RSM). The optimum operating conditions were a current density of 6 mA/cm 2 , pH = 7, and NaCl of 0.26 g/L. The results showed that the combined system eliminated more than 99.91% of the congo red dye with a removal of chemical oxygen demand (COD) of around 97% with 1.64 kWh/kg of dye of the consumed energy. At low current density, the current delivered for the composite anode was more than for the Al anode with the same surface area. On top of this superiority, the EC-EO scenario is a practical hybrid process to remove CR in an environmentally friendly pathway.

This study investigated the correlation between the levels of chromium (Cr), lead (Pb), cadmium (Cd), zinc (Zn), and copper (Cu) in surface sediment samples and those in the total soft tissues of the mussel Mytilus.galloprovincialis , collected off the northern Moroccan coast in the Mediterranean. The objective was to examine the accumula - tion patterns of these heavy metals in M..galloprovincialis relative to their concentrations in the sediment. Detailed sampling of sediments and Mytilus galloprovincialis mussels were carried out at three specific stations to mea - sure trace metal concentrations. A perfect correlation was observed for Pb levels between the mussel tissues and sediment. The sampling methods were carefully planned to ensure data accuracy and consistency, following strict protocols to reduce contamination and maintain sample integrity. In contrast, Cr showed only a weak correlation. The correlations for the other trace metals (Cd, Zn, and Cu) varied from strong to weak and were both positive and negative, but none were statistically significant. These findings underscore the potential of M..galloprovincialis as an effective biomonitoring species for Pb. However, additional research and more comprehensive analyses are necessary to establish firmer conclusions regarding the correlations for the other metals.

This article presents an assessment of the technical and economic feasibility of a 20 MW grid-connected wind-solar-photovoltaic hybrid system in the city of Dakhla, located in southern Morocco. During this study, GIS and virtual reality were integrated to model and simulate the productivity of the hybrid system under local climatic conditions. Additionally, 3D modeling of the system provides an immersive view to visually assess the system’s impact on the local landscape and anticipate potential logistical challenges. By taking advantage of this technology, our study goes beyond traditional models, proposing an innovative approach to better understand the spatial and visual dimensions of the project. The results of our study, based on these state-of-the-art methodologies, reveal promising conclusions regarding its annual energy production, which is approximately 60 GW, the level-ized cost of energy of the system, which is approximately LCOE = $0.045/kWh, the net present value (NPV) of $27,439,559.00, the internal rate of return (IRR) of 17.5%, and a discounted payback period (DPP) of 8 years. Ad-ditionally, from an environmental perspective, the hybrid system has the capacity to avoid approximately 936,494 tons of greenhouse gas emissions, equivalent to savings of approximately $18,729,875.00 in terms of carbon dioxide reduction over its lifetime.

The article highlights experimental and field studies of the scientific problem of increasing the yield of soybean seeds by optimizing the main elements of growing technology. Improved standards for the depletion of major biological nutrients during the formation of units in soybean crops make it possible to specify the standards of foliar fertilization to obtain the planned levels of yield and removal of these elements from the soil. The obtained results are of practical importance, as they contribute to optimizing the nutrition of soybean plants due to the use of foliar fertilizers Ecoline Legume. This helps to increase seed yield to the level of 2.0–2.5 tons per hectare. The researchers also conducted a generalization and analysis of scientific results in the field of soybean yield management through foliar feeding. In addition, scientific publications on the influence of liming, application of organic, mineral and microfertilizers on the physicochemical and agrochemical properties of the soil were analyzed. The cultivation of soybeans and the rational application of foliar fertilization are economically beneficial methods, and in this case, the use of foliar fertilization Ecoline Legume to approximately neutral reaction of the soil environment contributed to obtaining the highest levels of conditional net profit and profitability. This confirms the high energy efficiency of soybean cultivation.

Improved standards for the depletion of major biological nutrients during the formation of units in soybean crops make it possible to specify the standards of foliar fertilization to obtain the planned levels of yield and removal of these elements from the soil. The obtained results are of practical importance, as they contribute to optimizing the nutrition of soybean plants due to the use of foliar fertilizers Ecoline Legume. This helps to increase seed yield to the level of 2.0–2.5 tons per hectare. The researchers also conducted a generalization and analysis of scientific results in the field of soybean yield management through foliar feeding. In addition, scientific publications on the influence of liming, application of organic, mineral and microfertilizers on the physicochemical and agrochemical properties of the soil were analyzed. The cultivation of soybeans and the rational application of foliar fertilization are economically beneficial methods, and in this case, the use of foliar fertilization Ecoline Legume to approximately neutral reaction of the soil environment contributed to obtaining the highest levels of conditional net profit and profitability. This confirms the high energy efficiency of soybean cultivation.","PeriodicalId":448145,"journal":{"name":"Ecological Engineering & Environmental Technology","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141706452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to analyze the impact of land use change in East Sinjai Sub-district on the Kalamisu River Watershed and evelop water management strategies to balance availability with population needs. Utilizing GIS methods with ArcGIS 10.8 and Landsat satellite imagery, land use change in East Sinjai District was examined. Additionally, water infiltration capacity analysis considered factors such as rock type, rainfall, soil type, slope, and land use. Reference materials include the Technical Guidebook for Groundwater Management (DESDM Geological Agency, 2007) and the Regulation of the Minister of Forestry of the Republic of Indonesia No. P.32/MENHUTII/2009 on Procedures for the Preparation of RTkRHL-DAS. The study's outcomes will feed into a SWOT analysis to craft a management strategy for the area over the next decade. This research aims to contribute positively to the Sinjai Regency government and enhance scientific discourse on water governance and spatial management. Qualitative analysis was employed to elucidate the area's physical condition and analyze quantitative data and information pertinent to resource management processes and water management strategies. Primary data from satellite image interpretation and interviews supplemented by secondary data were utilized for problem identification and data analysis. The analysis indicates a substantial increase in land use in East Sinjai Sub-district from 2012 to 2017, notably in residential areas, with a rise of 136.6 hectares due to a population surge of 58,986 people. Water infiltration in the Kalamisu River watershed is critically low. Water availability in East Sinjai District has notably decreased by -4,658,505 cubic meters per year from 2012 to 2022. To enhance groundwater absorption capacity and availability, promoting the use of high water-absorbent plantation land is essential. Additionally, developing mangrove areas is crucial for improving water infiltration, particularly in quality and quantity, especially during dry seasons.
