Our results show the sweets products analyzed using GC-MS/MS indicated the presence of the benzyl butyl phthalate (BBP), dibutyl phthalate (DBP), bis(2-ethylhexyl) phthalate (DEHP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), and 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINC). Slightly or not metabolized in the body, plasticizers can reach WWTPs and contaminated wastewater. Generally, the usual treatment procedures in WWTPs are not effective in removing these plasticizers, and therefore, they end up in the sea and concentrate in the sediments. This is what our study showed by detecting plasticizers at high concentrations such as DiNB which reached 0.93 mg/kg in the tested WWTP and 3.8 mg/kg in the sediment of the adjacent marine coast. These analyses generally have negative effects on human health. In fact, we have tested the toxicity of the main detected phthalates such as DINP, DEHP, and DBP. The results showed that the acute administration significantly induced liver and kidney injuries in male mice manifested by a rise in plasma uric acid, alanine aminotransferase, and glucose.","PeriodicalId":510255,"journal":{"name":"Water Practice & Technology","volume":"65 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922877","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}

A combination of experimental investigations and Monte-Carlo simulations (MCS) were used to explore zerovalent iron nanoparticles (nZVI) for their removal. The nZVI exhibited an absorption peak (λmax) at 373 nm with a mesoporous structure (pore size 2.138 nm), 159.419 m2 g−1 surface area, and crystalline peaks. The adsorption processes were positively influenced by batch parameters. BPA adsorption on nZVI varied with temperature as predicted by Freundlich and Langmuir isotherms, achieving a maximum adsorption capacity (qmax) of 982.13 mgg−1 at 308 K and pH 2. The adsorption process at 303 and 308 K was physisorption, whereas, at 313 K, it was chemisorption suitably described by pseudo-second-order kinetics. The exothermic and spontaneous nature of the adsorption processes were demonstrated by the negative values of enthalpy (−ΔH°) and free energy (−ΔG°) that decreased with increasing temperatures (308–328 K). The density function theory and MCS studies showed that BPA's phenyl ring, isopropyl, and hydroxyl groups interacted electrostatically with nZVI, specifically crystal plane 121 with the most negative adsorption energy (ΔEads), enhancing BPA removal. Through optimized adsorption mechanisms, nZVI can effectively remove BPA from wastewater.","PeriodicalId":510255,"journal":{"name":"Water Practice & Technology","volume":"55 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922919","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 examines the financial feasibility and sensitivity of MHP projects in the Deluwang watershed, Situbondo Regency, Indonesia. Three cases with varying head elevations and discharge rates were analyzed, utilizing crossflow turbines. Case 1, with the highest head and discharge, emerged as the most profitable, demonstrating the highest values for Net Present Value (NPV), Benefit–Cost Ratio (BCR), and Internal Rate of Return (IRR). The study found that on-grid systems, despite higher initial costs, offer more stable revenue and faster payback periods compared to off-grid systems. Sensitivity analysis revealed the on-grid method's resilience to fluctuations in interest rates, project lifespan, and river discharge, maintaining feasibility with up to an 80% reduction in discharge over 15 years. This highlights the importance of strategic planning in MHP design, considering head and discharge rates to optimize power generation. The findings provide valuable insights for renewable energy development, contributing to Indonesia's energy needs and local socio-economic benefits. Future research should further explore the socio-economic impacts of MHP installations to enhance their development and sustainability.","PeriodicalId":510255,"journal":{"name":"Water Practice & Technology","volume":"20 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807534","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}

The increased degradation of dye was observed on exposure to longer irradiation time. The increased concentration of dye resulted in a decreased rate of photodegradation. 95% degradation achieved at pH 9 showing that the pH medium also enhances the degradation. A higher dye degradation percentage was achieved by increasing the higher catalyst dosage of 0.013 g degraded 93% of dye.

Fifteen GIS thematic maps have been ranked and normalized using five DSS techniques: Analytical Hierarchy Process (AHP), Fuzzy Analytical Hierarchy process (FAHP), Frequency Ratio (FR), Shannon Entropy (SE), and Multi-Influencing Factor (MIF). To ensure the computational usefulness of these models, GWRZs have been extracted and compared.

The results reveal varying subsurface layers with distinct resistivity values.

The spatial location labeled EK2 features the largest aquifer, measuring 246.70 m, predominantly located in the central research area. Aquifer depths range from 87.10 to 250.20 m, with variations in thickness highlighting geographical heterogeneity and its impact on groundwater transport. These spatial differences in groundwater characteristics are crucial for understanding groundwater movement, storage, and extraction potential. The study underscores significant variability in porosity, reflecting differences in the aquifers’ water storage capacity and susceptibility to contamination.

For the elimination of different ECs, several treatment technologies, including chemical-based, physical-based, and biological-based methods, have been developed. Nonetheless, no one technique can presently efficiently eradicate ECs; biological treatments are frequently found to be more beneficial. This review aims to give a brief analysis of the sources, kinds, impacts, and monitoring and detection techniques for ECs. This review provides information on such biological processes for the quick and eco-friendly removal methods of ECs from effluent. The article highlights the methodology used by the hybrid system to eliminate distinct EC types. The hybrid structure of a membrane bioreactor (MBR) accompanied by filtrations using membrane successfully got rid of a bunch of ECs. For the biosorptive elimination of pharmaceuticals various hybrid structures comprising constructed wetlands (CWs) and waste stabilization ponds demonstrated amazing possibilities.
