Modification of Saharan dust size distribution during its transport over the Anatolian Plateau Uzunpınar, Elif Sena; İmamoğlu, İpek; Rahmani, Amir; Tuncel, Süleyman Gürdal (2023-09-20) Particle number size distribution in dust plumes and its modification as the plume travels over the Anatolia were investigated by measuring particle number size distributions at two stations: one located on the Mediterrane...
Novel catabolic pathway for 4-Nitroaniline in a Rhodococcus sp. strain JS360 Kurt, Zöhre; Qu, Yi; Spain, Jim C. (2023-07-15) 4-Nitroaniline (4NA), the starting material for the first synthesized azo dye, is a toxic compound found in industrial wastewaters. Several bacterial strains capable of 4NA biodegradation were previously reported but the d...
Seasonal monitoring of microbial activity using conventional approaches in a full-scale urban biological wastewater treatment plant Demirbilek, Deniz; İpek, Ubeyde; Yetiş, Ülkü (2023-05-01) Activated sludge processes contain various groups of microorganisms with different metabolic properties, which are responsible for contaminants removal. Therefore, it is important to elucidate the general structure and fun...
Near real-time depth change monitoring on inland water bodies using Sentinel-1 and Dynamic World data Ünalan, Utku Berkalp; Yüzügüllü, Onur; Aksoy, Ayşegül (2023-04-24)
Preparation of chabazite based Fenton-like heterogeneous catalyst and its organic micropollutant removal performance Ali, Mohsin; Dilek, Filiz Bengü; İpek Torun, Bahar (2023-04-01) Natural chabazite (CHA) is used for the first time as a heterogeneous catalyst in Fenton-like oxi- dation. Pretreatment techniques (NH4+-exchange, steam treatment, and Fe-exchange) were ap- plied to natural CHA to improve ...
Start-up strategies of electromethanogenic reactors for methane production from cattle manure Ghaderikia, Amin; Taşkın, Bilgin; Yılmazel Tokel, Yasemin Dilşad (2023-03-15) This study qualitatively assessed the impacts of different start-up strategies on the performance of methane (CH4) production from cattle manure (CM) in electromethanogenic reactors. Single chamber MECs were operated with ...
Wastewater treatment plants discharges disseminated more Giardia than Cryptosporidium Onursal, Asli; İçgen, Bülent (2023-02-01) Parasitic protozoaGiardia intestinalisandCryptosporidium parvumare causative agents for giardiasis and cryptosporidiosis, respectively. These infections are mostly associated with waterborne diseases. The discharges from w...
Microplastics & organics - a comparative study of sorption of triclosan and malachite green onto polyethylene Ciftci, Goekce; Turkeli, Ulku Dide; Ozen, Elif Yaren; Özdemir, Melek; Sanin, Faika Dilek; İmamoğlu, İpek (2023-02-01) This study aims to elucidate interaction of organics with microplastics in a comparative manner via the use of two model compounds (i.e., triclosan and malachite green) having different physicochemical properties, onto pol...
Evaluation of 3-D spatial distribution of dissolved oxygen concentrations in a eutrophic lake YENİLMEZ, FİRDES; Düzgün, Şebnem; Aksoy, Ayşegül (2023-01-01) In this study, three-dimensional (3-D) ordinary kriging of dissolved oxygen (DO) concentrations was performed for a eutrophic reservoir based on 81 sampling points using Stanford Geostatistical Modeling Software (SGeMs). P...
Role of biochar-based free radicals in immobilization and speciation of metals in the contaminated soil-plant environment Rashid, Muhammad Saqib; Liu, Guijian; Yousaf, Balal; Hamid, Yasir; Rehman, Abdul; Arif, Muhammad; Ahmed, Rafay; Song, Yu; Ashraf, Aniqa (2023-01-01) The structure of biochar produced at various pyrolysis temperatures influences metal geochemical behavior. Here, the impact of wheat straw-derived biochar (300, 500, and 700 degrees C) on the immobilization and trans-forma...
Production and Characterization of Wild Sugarcane (Saccharum spontaneum L.) Biochar for Atrazine Adsorption in Aqueous Media Prens, Josué; Kurt, Zöhre; James Rivas, Arthur M.; Chen, Jorge (2023-1-01) Wild sugarcane (Saccharum spontaneum L.) is an invasive plant species in the Central American region. Due to its low nutrient and water requirements, it can grow fast and displace native species. Therefore, its biomass is ...
A critical review on biochar-assisted free radicals mediated redox reactions influencing transformation of potentially toxic metals: Occurrence, formation, and environmental applications Rashid, Muhammad Saqib; Liu, Guijian; Yousaf, Balal; Hamid, Yasir; Rehman, Abdul; Arif, Muhammad; Ahmed, Rafay; Ashraf, Aniqa; Song, Yu (2022-12-01) Potentially toxic metals have become a viable threat to the ecosystem due to their carcinogenic nature. Biochar has gained substantial interest due to its redox-mediated processes and redox-active metals. Biochar has the c...
