This study investigates the pollution of surface sediments resulting from urban runoff, identifies potential pollution sources, and examines the correlation between HMs and two factors: total organic carbon (TOC%) and particle size distribution (PSD). A total of 30 surface sediment samples were collected from three urban channels in the Tehran megacity. The concentrations of key elements, including strontium (Sr), lead (Pb), cadmium (Cd), nickel (Ni), and copper (Cu), were determined using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). The mean concentrations of Cd, Ni, Cu, Pb, Sr, were 0.46, 39.80, 161.25, 261.75, 388.50 mg/litter, respectively, following the sequence Sr &gt; Pb &gt; Cu &gt; Ni &gt; Cd. To identify the HMs accumulation, factor analysis(FA) was employed. The HMs rank order based on FA was as follows: 37.7% &gt; 24.4% &gt; 24.1%. According to (FA), the possible accumulation source of Pb and Sr is as different as Cu, Ni, and Cd elements.

The specific THMs include CHBr₃, CHClBr₂, CHCl₂Br, and CHCl₃. THMs are toxic disinfection by-products (DBPs) that pose potential risks to human health and can be present in ready-to-eat vegetables. Our study examined key variables such as contact time, chlorine concentration, and vegetable type on the formation and absorption of these contaminants. Laboratory simulations involved 22 samples characterized by differing chlorine concentrations, contact durations, and three vegetable types: celery, lettuce, and leek. The result showed that the maximum concentration of THMs (354.73 µg L^− 1) in celery was observed when 300 mg L-1 of chlorine for 15 min was employed. The results demonstrated that contact time significantly affected the formation and absorption of THMs. Celery demonstrates a greater absorption of THMs than others. The evaluation of lifetime cancer risk (LTCR) and hazard index (HI) for THMs across 22 simulated test conditions indicated that CHClBr₂ exhibited the highest LTCR at 7.34 × 10^⁻⁶. Also, the average influence of LTCR for CHBr₂Cl constituted 64%, CHBr₃ accounted for 21%, CHBrCl₂ represented 10%, and CHCl₃ was 5%. The results showed that CHBr₃ had the most effect on the hazard index, while CHCl₃ showed the lowest impact. These findings assist food industry professionals in reducing THM absorption by regulating chlorine concentration and contact time during vegetable disinfection.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"23 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143583646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through an analysis of co-authorship networks, co-citation networks, and keyword co-occurrence maps, the review identifies key authors, influential publications, and dominant research themes. The findings highlight that biomass-based methods, including the use of microalgae, macrophytes, and microbial consortia, are central to wastewater treatment efforts in Indonesia. These approaches provide sustainable and cost-effective solutions for pollutant removal and resource recovery. The growing emphasis on keywords such as “biofuels,” “bioplastics,” and “circular economy” reflects a strong interest in integrating wastewater treatment with resource recovery and sustainable practices. However, challenges remain in scaling up technologies like bioreactors and adsorption systems while ensuring cost-effectiveness and operational efficiency. For instance, advancements in microbial fuel cells could enable simultaneous wastewater treatment and renewable energy generation, addressing scalability issues. Similarly, the development of enhanced microbial strains for phytoremediation could improve the treatment of persistent pollutants in water and soil. Future research should aim to bridge gaps through interdisciplinary collaboration and explore underrepresented linkages to unlock further innovation. By addressing these challenges and leveraging emerging technologies, Indonesia can strengthen its wastewater treatment capabilities, contributing to environmental protection, resource efficiency, and sustainable development.</p></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"23 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their ability to transport pollutants makes them particularly dangerous, underscoring the urgent need for effective removal methods. Herein, we report the synthesis of an environmentally friendly material that enables the magnetic removal of polystyrene nanoparticles (PSNPs) from aqueous solutions by green chemistry approach. The material synthesized by using pine resin extract as a reducing and capping agent is iron oxide magnetic nanoparticles (PR@Fe₃O₄ MNPs). Spectroscopic (UV–Vis, FTIR) and microscopic (EFSEM, EDXS) techniques were used to characterize the nanoparticles and confirm the adsorption of PSNPs on the PR@Fe₃O₄ MNPs. X-ray diffraction (XRD) patterns indicated the crystalline nature of the nanoparticles and confirmed the preservation of the structure of PR@Fe₃O₄ MNPs after adsorption. The adsorption of PSNPs (with a diameter of 100 nm) was performed under varying conditions, including different contact times, dosages of PR@Fe₃O₄ MNPs, and concentrations of PSNPs. It was observed that the removal efficiencies of PSNPs (100 mg/L) ranged from 95.45% to 99.13% when the dosage of PR@Fe₃O₄ MNPs increased from 2.5 mg to 10.0 mg after 24 h, reaching the maximum adsorption capacity at 454.55 mg/g. Kinetic and isotherm studies indicated that the adsorption process fits best to a pseudo-second-order kinetic model and Langmuir isotherm, suggesting monolayer adsorption on homogeneous surfaces.
