Master Thesis Surface Water Quality Modeling for Best Management Practices - a Case Study From Bakırçay River Basin(01. Izmir Institute of Technology, 2021) Gündüz, Orhan; Kazancı, Yiğithan; Baba, Alper; Baba, Alper; Baba, Alper; Gündüz, Orhan; 03.07. Department of Environmental Engineering; 01. Izmir Institute of Technology; 03.03. Department of Civil Engineering; 03. Faculty of EngineeringThis study was carried out to analyze the water quality in the Bakırçay River basin, which is known to be exposed to intense industrial and agricultural pollutant loads. A mathematical model system called AQUATOOL was used to reveal the changes that the effects of anthropogenic and natural events in the basin will cause on the conservative water quality parameters and nutrients. Model results are given in wet (April) and dry (September) periods for 4 points determined from upstream to downstream in the basin on a spatial basis, and temporal evaluation is also given for 1 upstream river water body, 1 downstream river water body, and 1 lake water body. Seven best management practices scenarios were determined and implemented one after the other in the model. Spatially, the results reveal good water status for both the dry period and the wet period at the upstream points, while at the downstream points, all parameters except BOD5 and Dissolved Oxygen are found to be in poor condition. Besides, similar situations arise in spatial-based results, and despite the scenarios, parameters could not reach good water status except for the lake waterbodies. The improvement in lake results occurs due to dilution, not scenarios. With this study, the pollution load in Bakırçay River Basin and the effects it creates once again revealed that if the anthropogenic loads are not reduced, the water quality of the basin will reach irreversible points for many years. It is thought that this study can constitute a source document for decision-makers, especially in terms of efficiency comparisons in the best management scenarios to be applied.Article Effects of Industrial and Domestic Wastewater Treatment Plants on Microplastic Pollution in an Urban River in Türkiye(Springer int Publ Ag, 2025) Kazancı, Yiğithan; Gündüz, Orhan; Kazanci, Yigithan; Alpergun, Cumana; Kara, Nursena; Tasdelen, Ozge; Gunduz, Orhan; 01. Izmir Institute of Technology; 03. Faculty of Engineering; 03.07. Department of Environmental EngineeringMicroplastic (MP) contamination in inland aquatic systems is a growing environmental concern due to its persistence and potential ecological impacts. This study provides a comprehensive assessment of the occurrence, composition, and seasonal dynamics of MPs in two urban rivers-Nif Creek and Gediz River-in western T & uuml;rkiye, which receive treated and untreated effluents from domestic and industrial wastewater treatment plants (WWTPs). A total of 20 river water and 3 sediment sampling stations were monitored across four seasons. MP concentrations ranged from 7 to 146 particles/L in water and from 9,867 to 136,177 particles/kg in sediments, with the highest abundances observed near WWTP outfalls and urban infrastructure. Polypropylene was the dominant polymer in water (59.1%) and WWTP effluents (44.4%), while polyethylene was most prevalent in sediments (60.2%). MPs were primarily within the 0.1-0.5 mm size range and were predominantly transparent in colour. Statistical analyses indicated significant positive correlations between MP abundance and key water quality parameters, including chemical oxygen demand, total suspended solids, and selected heavy metals (e.g., Zn, Cd, Ni). The polymeric composition of MPs reflected both urban and industrial sources, with variations in polymer profiles linked to spatial and seasonal factors. Compared to values reported in European freshwater systems, MP levels in the studied rivers were considerably higher, underscoring the need for improved wastewater management and targeted monitoring efforts in urban river basins.Article Citation - WoS: 13Citation - Scopus: 13Countrywide Spatial Variation of Potentially Toxic Element Contamination in Soils of Turkey and Assessment of Population Health Risks for Nondietary Ingestion(American Chemical Society, 2022) Genişoğlu, Mesut; Gören, Ayşegül Yağmur; Sofuoğlu, Sait Cemil; Kazancı, Yiğithan; 03.07. Department of Environmental Engineering; 01. Izmir Institute of Technology; 03. Faculty of EngineeringCountrywide surface soil concentrations of potentially toxic elements (PTEs) in Turkey were reviewed in the Web of Science database. A total of 93 papers were investigated to compose a PTE dataset for determining spatial variations and estimating exposure and health risks. Al, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn were selected as PTEs in surface soil. A compiled PTE concentration dataset was used to estimate chronic toxic risks (CTRs) and carcinogenic risks (CRs) according to the deterministic and probabilistic approaches. While the CTR and CR levels of age and sex groups were estimated using a deterministic approach, population risks were estimated using a probabilistic approach. CTR and CR levels in lower age groups and female sex groups were estimated to be higher than those in higher age groups and associated male sex groups. The average CTR levels of the nondietary ingestion of As-containing soil in <11 year age groups were near/just above the threshold level, while As-associated average CR levels of adults and other age groups were estimated to be in the acceptable risk range (10-6 < CR < 10-5) and low priority risk range (10-5 < CR < 10-4), respectively. As-, Cr(VI)-, and Pb-associated upper-bound CR levels of the Turkish population were simulated to be 5.14 × 10-4, 6.23 × 10-5, and 2.34 × 10-6, respectively. Health risk models show the significance of As in both chronic toxic and carcinogenic effects.Article Citation - WoS: 1Citation - Scopus: 1Microplastic Pollution and Risk Evaluation in the Gediz River(Central Fisheries Research inst, 2026) Kazancı, Yiğithan; Gündüz, Orhan; Kazanci, Yigithan; Alpergun, Cumana; Kara, Nursena; Gunduz, Orhan; 01. Izmir Institute of Technology; 03. Faculty of Engineering; 03.07. Department of Environmental EngineeringMicroplastics (MPs), particles less than 5 mm in diameter, enter the aquatic ecosystem through the degradation of larger plastics. They can accumulate in the environment for long periods due to their durability and buoyancy. In this study, a risk assessment of MPs was conducted at five different stations in the Gediz River via a Pollution Load Index (PLI) and a Polymer Hazard Index (PHI) calculated for dry and wet seasons to highlight the risks caused by seasonal variations of pollution levels for different types of MPs in an urban river discharging to Izmir Bay. The results showed that MPs were widespread in the area, with an average abundance of 13-211 units/L/L. During the dry season, the mean number of particles was 67 +/- 57; during the wet season, the mean number of particles decreased to 50 +/- 37. The most common type was polypropylene with 62.4%, followed by Polyethylene and Polyethylene Terephthalate (8.3% and 7.01%). The most abundant MP shapes are fragments and fibers, with 47.1% and 38.5%. During the dry season, PLI values ranged from 0.99 to 2.44, while in the wet period, they ranged from 1.08 to 2.11. Furthermore, PHI values for the MP species detected at each station ranged from 3.81 to 7.91. The results indicated that the Gediz River is a significant MPs source for Izmir Bay and demonstrates a major hazard for its overall ecological condition.
