    (2024) Köksal, Oğuz Kağan; Apaydın, Gökhan; Cengiz, Erhan; Sirin, Murat; Baltaş, Hasan; Çakmak, Eyüp; Tirasoglu, Engin
    The objective of this study was to analyze the metal content in the organs of Oncorhynchus mykiss, commonly known as rainbow trout, at 12 different locations within the cages located in Karacaören II Dam Lake. The metal contents in fish samples were analyzed using a PANalytical Epsilon5 energy dispersive X-ray fluorescence (EDXRF) spectrometer. We will analyze the findings by displaying the fluctuating metal concentrations in various internal organs over the seasons.

    Exploration of Seasonal Metal Pollution in Karacaören II Dam Lake Sediment Samples using X-ray Fluorescence Method
    (2023) Apaydın, Gökhan; Köksal, Oğuz Kağan; Cengiz, Erhan; Sirin, Murat; Baltaş, Hasan; Tirasoglu, Engin
    In this study, the seasonal metal pollution of sediment samples taken from twelve distinct notes of the Karacaören II Dam Lake was examined. The quantity of metal in soil samples was determined using energy dispersive X-ray fluorescence spectroscopy. The geoaccumulation index and enrichment factor expressions were created using the metal concentrations found in the sediments. Seasonal values at the local, state, and international levels were compared to the findings. The ratios of the elements copper, zinc, lead, arsenic, nickel, chromium, and mercury, measured in parts per million (ppm), were found to be 42-96, 53-78, 11-14, 4-7, 233-244, and 611-711, respectively. There is also discussion of the sediments' elemental composition and degree of pollution. In contrast, it was found that the Urbach energy increased from 0.246 eV to 0.630 eV with increasing levels of V2O5. These synthetic glasses' densities and molar volumes were also investigated and discussed.

    Spatiotemporal distribution, source identification and risk assessment of potentially toxic elements in sediments along the Alanya/Antalya coastline, Mediterranean Sea
    (Springer, 2025) Cengiz, Erhan; Sirin, Murat; Yesilkanat, Cafer Mert; Apaydin, Gokhan
    This study investigates the concentrations of potentially toxic elements (PTEs), ecological risks, and human health effects in sediment samples from 11 points along the Alanya coastline, influenced by industrial, agricultural, and tourism activities. Energy dispersive X-ray fluorescence spectroscopy was used for analysis. The mean concentrations of Mn, Fe, Ni, Cu, Zn, Cr, and As were 281, 14, 30, 34, 66, 60, and 12 mg/kg, respectively. The enrichment factor values were ranked as follows: As (3.94), Zn (2.94), Cu (2.83), Cr (2.45), Ni (1.29), and Mn (1.19), indicating moderate enrichment for Cu, Zn, Cr, and As, and minimal enrichment for Ni and Mn. The geo-accumulation index indicated minimal contamination, supporting the conclusion that Alanya is not heavily impacted by the PTEs studied. The contamination factor values were highest for As (0.90) and lowest for Fe (0.30), indicating generally low levels of pollution. Seasonal variation was observed, with the highest degree of contamination in winter (7.09) and the lowest in autumn (5.39). The pollution load index ranged from 0.411 in autumn to 0.622 in winter, with an annual average of 0.468, indicating no pollution. The ecological risk factor values, ranging from 0.30 for Fe to 8.97 for As, did not show a significant ecological risk, with As contributing most to the risk. The potential ecological risk index averaged 15.4, which means a very low ecological risk. Additionally, the study confirmed that the overall potential human health risks remained within acceptable limits.
