Two dump yard sites were chosen. Based on the distribution and abundance, 11 weedy species were collected bi-annually using the plot method along with soil samples. Both plants and soils were analysed for heavy metals, and the bioconcentration factor (BCF) was calculated to assess the extent of soil contamination and the remediation potential of weedy plants.\u0000The weed plants collected from two yard sites showed an accumulation of metals, and the rate of accumulation varied among plant species. In the species at the dumping yard site, a higher accumulation of metals was observed for Panicum ciliare (As and Zn), Indigofera hirsuta (Cd and Ni), Chloris barbata (Cr), and Indigofera aspalathoides (Pb). Goiania macrocarpa has accumulated more As, Cu, Ni, and Zn metals in the industrial yard. The accumulation levels in plant tissues were assessed through BCF in the whole plant. The study results confirm that Panicum cillarae, Indigofera hirsuta, and Sida acuta at dump yard soils and Indigofera aspalathoides at industrial yard soil reported BCF values of more than one, indicating the potential of these plants for phytoremediation for selected metals.\u0000Six of the 11 weedy species were specific to accumulating metals from yard soils. They are Indigofera aspalathodies for Cd; Sida acuta, Panicum ciliare, and Indigofera hirsuta for As; Oldenlandia corymbose for Zn and As; and Gouinia macrocarpa for Zn. The findings suggest that weedy species growing naturally in the two yards sites adopted higher concentrations of the metals and can accumulate them to a higher degree in their body parts.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141673641","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 deficit in irrigation is affected by uncontrolled rainfall. In line with this, rainfall uncertainty causes a variation between the measured actual crop evapotranspiration and the theoretical crop evapotranspiration. Let us imagine that rain falls during the deficit irrigation research, and the soil moisture under the deficit experiment is then raised to the soil field capacity. It is incorrect to report the result as a deficit. Thus, there is a research gap on the effect of rainfall uncertainty on the quantity of theoretical and actual crop evapotranspiration under deficit irrigation. This study was carried out at the Arba Minch University demonstration site on onion crops. Using CROPWAT 8.0 software, the reference evapotranspiration (ETo) was calculated using the Penman-Monteith formula. The crop coefficient and ETo were used to calculate the theoretical crop evapotranspiration. In contrast, actual crop evapotranspiration was calculated using soil moisture measurements before and after each irrigation event after applying theoretical crop evapotranspiration. As a result, there is a significant difference between the calculated theoretical crop evapotranspiration and actual crop evapotranspiration from a deficit study. Thus, the calculated seasonal theoretical crop evapotranspiration was 201.72 mm. On the other hand, the actual crop evapotranspiration was 275.82 mm. This revealed that the actual crop evapotranspiration was greater than the calculated theoretical crop evapotranspiration by 36.7%. Uncontrolled rainfall was identified as the output’s cause. This has an evident effect on the deficit in experimental research. Hence, conducting the deficit experiment in a greenhouse is more reasonable. In addition, it is possible to assess actual crop evapotranspiration based on daily soil moisture measurements and report the deficit level based on the measured amount.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":" 37","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141673588","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}

Therefore, the purpose of the present study is to use low-cost and bioavailable raw materials such as agro-industrial waste of asparagus husk, as substrate for obtaining PHA by Bacillus thuringiensis. The proximal characteristics and structural carbohydrates of the waste were previously determined using HPLC. The pretreatment conditions were optimized using a Plackett-Burman design and response surface of the central compounds, evaluating temperature, %NaOH, time, % solid/liquid and solvent. Likewise, the enzymatic hydrolysates of the optimal conditions of the pretreatment were used, using an enzymatic solution with cellulase activity at 45°C at 100 rpm for 72 h. To produce PHA, a mineral-based medium, supplemented with enzymatic hydrolysate from the optimal pretreatment, was utilized. This study examined the effects of varying initial inoculum concentrations (0.25, 0.5, and 0.75 g/L) and percentages of enzymatic hydrolysate supplement (%, v/v). The process was conducted at 30°C and agitated at 125 rpm for 72 h. Maximum production of PHA was obtained with 0.138 g/L from an initial inoculum of 0.75 g/L of B. thuringiensis and a 47% supplement of the enzymatic hydrolysate. The PHA biopolymer was identified by its chemical characteristics by FTIR and correlated by HPLC with a standard. This study contributes to the use of agro-industrial waste to obtain biologically-based bioplastic through a low-cost process aligned with the circular economy strategy.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":" 31","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141675803","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}

These factors have affected water availability, particularly for domestic consumption, leading to a potential water crisis. To better understand the factors affecting water security among various income groups and explore water consumption patterns, a study was conducted using a multiple regression model. The dependent variable was water security, and the independent variables were based on socioeconomic characteristics. A total of 571 residents from Malaysia’s higher-income, middle-income, and lowest-income groups participated in the study. The study found that several factors significantly influenced water security, including race, household size, type of house, education, and income. In Johor, household size, type of house, and income explained 65% of the variance in water security for the overall income group. In Terengganu, race, type of house, education, and income explained 96% of the variance in water security for the overall income group. The variable income had a significant relationship with water security, with approximately 0.01% and 0.05% in Johor and 0.10% in Terengganu. These results indicate that socioeconomic factors play a crucial role in water security for both indoor and outdoor activities. Access to water is a basic need that affects the quality of life, especially for drinking water. Therefore, these findings are essential for water operators to manage and educate households through campaigns on sustainable water use and conservation. The lack of availability and access to basic water impedes individuals and communities from achieving a greater quality of life.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141675901","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}

To address this, the researchers in this study opted to use kitchen waste, a substantial solid waste from the food industry, as a valuable source of fermentable sugars. Inedible parts of broccoli and cauliflower used as kitchen waste in this study show promising potential as an economically and ecologically sustainable material for fermenting biomolecules. This study aims to evaluate the viability of utilizing kitchen waste as a cost-effective, ecologically sustainable carbon source to produce xanthan, making use of Xanthomonas campestris NCIM 2961 in the process. Aqueous extracts of inedible parts of cauliflower and broccoli were fermented with Xanthomonas campestris NCIM 2961 at standard conditions. The fermentation parameters, including, pH, temperature, agitation, and incubation period were varied at different levels to study the effects of varying conditions on the xanthan yield and to determine the optimum levels of the fermentation parameters. After the fermentation process, the xanthan gum was separated from the broth through alcoholic precipitation and subsequent drying. The weight of the dried gum was recorded. To analyze the properties of the xanthan obtained from the alternative medium under standard conditions, it was compared with commercial food-grade xanthan using Fourier-transform infrared (FTIR) spectroscopy. The FTIR spectra of xanthan produced from the alternate medium showed a close resemblance to that of the commercial food-grade xanthan. The results obtained validate the potential of kitchen waste as a cost-effective, and eco-friendly alternative carbon source for xanthan production, thereby decreasing the cost of production and solid waste generated.","PeriodicalId":11703,"journal":{"name":"Environmental Research, Engineering and Management","volume":" 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141674630","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}
