Öğe An ecological study of Matricaria chamomilla L. var. Chamomilla(Gültekin Özdemir, 2025) Demir, Aynur; Eskin, Bülent; Rashidi, AdelehIn this study, the phytoremediation potential and essential element utilization potential of Matricaria chamomilla var. chamomilla species were investigated and the ecological characteristics of the species were determined. The plant and soil samples were collected from the Karaoren road in Aksaray province in April (2023). The research focused on the consantration of the following minerals: Ba, Cr, Co, Cu, Fe, Mn, Ni, Pb, S, and Zn in plant and soil samples. ICP-MS was used for plant samples and XRF device was used for soil samples. The obtained data were analyzed statistically by SPSS (version 25). According to the analysis results, while the concentrations of Al, Co, Cu, Mn, Ni, and S in the soil were above optimal values, the concentrations of Al, Co, Cu, Mn, Ni, and Pb in the plants were within the optimal range. In the stem part of the plant, the concentration of Cu, Mn, Pb and Zn elements was found being below the reference values. But, Cr and Fe concentrations in the plant were determined above reference values. However, the Bioconcentration Factor (BCF) value was low for all elements in the plant and was less than 1. This means that the potential use of this species in phytoremediation is quite limited.Öğe Determination of heavy metals and trace element contents in Veronica grisebachii S. M. WALTERS(İbrahim İlker Özyiğit, 2024) Rashidi, Adeleh; Eskin, Bülent; Demir, AynurThis study aimed to determine the concentrations of Al (aluminum), Ba (barium), Co (cobalt), Cr (chromium), Cu (copper), Fe (iron), Mn (manganese), Ni (nickel), Pb (lead), S (sulphur), and Zn (zinc) in soil and Veronica grisebachii S. M. WALTERS samples. The research focused on the heavy metal and essential nutrition element contents of these plant species. Plant samples were collected from southeastern Aksaray province, Türkiye, at the geographical coordinates 38°13'54.5"N 34°08'28.8" E and an elevation of 1276 m above sea level. Standard methods were used to determine the plant (root, stem, and leaf parts) and soil elements. The numerical values of essential elements and heavy metals in the species were quantified using ICP-MS. XRF device was also used to determine the elements in the soil. The results showed that the amounts of Cr, Cu, Fe Pb, S, and Zn in the soil were within the optimum range, while the concentrations of Al, Co, Mn, and Ni were above the optimum values. The levels of Al, Co, Mn, and Ni in the soil of the plant's natural habitat were above the reference values. This species has a high capacity to absorb and accumulate heavy metals such as Al, Co, Mn, and Ni from the soil.Öğe Determination of nutrient content of Gagea bohemica (Liliaceae) in Turkey(Springer, 2023) Eskin, Bülent; Demir, Aynur; Rashidi, AdelehMineral nutrients are essential for the growth and survival of a plant. In particular, bulbous plants such as Gagea bohemica (Zauschn.) Schultes & Schultes f. store nutrients and use them in metabolic activities during dormancy. The main aim of the present research is to reveal the micro- and macronutrient contents of G. bohemica. The soil and plant (bulbs, stem, and leaf parts) samples were taken from the southeast of Aksaray in Turkey at an altitude of 1320 m above sea level in April 2021. The amount of nutrients (Zn, S, P, Ni, Mn, Mg, K, Fe, Cu, Ca, Ba, and Al) in these samples were determined by ICPMS. Afterwards, these data were analyzed statistically. Zn, Fe, K, and Ca values in soil were within reference values, whereas Al (65,000 ± 1000–75,000 ± 3000 mg/kg), Cu (20 ± 2–46 ± 0.1 mg/kg), Mg (15,000 ± 1000–21,000 ± 1000 mg/kg), Mn (606 ± 2–751 ± 24 mg/kg), and Ni (75 ± 7–100 ± 10 mg/kg) values were above. Our results indicate an accumulation of nutrients in the soil where G. bohemica grows. Similarly, the concentrations of Zn, K, Cu, and Ca in the bulbs of the plant were among the reference values, while Al (14,900 ± 500 mg/kg), Fe (15,700 ± 200 mg/kg), Mg (7600 ± 300 mg/kg), Mn (321 ± 15 mg/kg), and Ni (81 ± 1 mg/kg) ratios were higher than optimal. Additionally, we found that G. bohemica effectively accumulates Al, Fe, Mg, and Ni in its shoot tissues. Monitoring this plant in terms of macro and micronutrients will provide more detailed information about its ecological features and habitat properties. In this way, it will be possible to carry out the cultivation of the species in suitable conditions and effective species protection and ensure sustainability.Öğe Heavy metal (Cr, Cu, Ni, Pb, and Zn) contents of endemic Salvia halophila plants around Lake Tuz(Toprak Gübre ve Su Kaynakları Merkez Araştırma Enstitüsü, 2022) Baysal Furtana, Gökçen; Demir, Aynur; Tekşen, Mehtap; Rashidi, Adeleh; Tıpırdamaz, RukiyeHeavy metals occur naturally in ecosystems at varying concentrations. However, heavy metal sources that have emerged in present-day mainly due to human influence, i.e. industrial activities, agricultural waste, pesticides, use of fossil fuels and traffic, have included a part of heavy metals in the ecosystem. Lake Tuz, together with the entire lake surroundings, water beds and important steppe areas, was declared Turkey’s Specially Protected Area (SPA) in 2001. Our aim in this investigation was to determine the levels of heavy metals such as Chrome (Cr), Copper (Cu), Nickel (Ni), Lead (Pb) and Zinc (Zn) in endemic Salvia halophila grown in different areas of Lake Tuz. The results of the heavy metal contents analyzed at the plant were compared with the international standard levels of heavy metals. The consequences displayed that differing extents of heavy metals are accumulated in S. halophila. The results obtained differed in accordance with the collection time and localities. When the outcomes are appraised, it is achievable to say that Pb is higher than the standard values. The findings of this investigation are the first reported results for this endemic S. halophila species that grows naturally at Lake Tuz and are important as they are newly discovered results.Öğe Investigation of Alkanna Orientalıs Var. Orientalis (l.) boiss in terms of macro and micro nutrient elements: a case study in Aksaray(Pakistan Botanical Society, 2022) Demir, Aynur; Eskin, Bülent; Rashidi, AdelehIn this study, Alkanna orientalis var. orientalis (L.) BOISS was analyzed to determine its nutritional contents and phytoremediation potential. The plant and soil samples were collected from Mahmutlu Hill in Aksaray in May (2019). The mineral contents of soil and plant samples (Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Ni, P, S, Zn) were determined by ICP-MS, and the obtained data were statistically analyzed and evaluated. K value in the soil was below the optimal value whereas Mg, Mn and Ni values were above the optimal values. On the other hand, the concentrations of Al, Ca, Cu, K, Mn and Zn in the plant were around the optimum values, while Fe, Mg, Ni were above. The results of the analysis showed that Fe and Ni concentrations were at a toxic level. Therefore this plant can be used in phytoremediation studies.Öğe Investigation of mineral nutrient and heavy metal accumulation status of senecio Vernalis Waldst. & Kit. collected from different habitats of Aksaray/Turkey(Taylor & Francis, 2022) Demir, Aynur; Eskin, Bülent; Rashidi, AdelehIn this study, Senecio vernalis Waldst. & Kit. was analyzed to determine a phytoremediation potential and nutritional contents are estimated. The plant and soil samples were collected between Karaoren and Karkin villages in Aksaray in May (2021). The mineral contents (Al, Ba, Ca, Cu, Fe, K, Mg, Mn, Ni, P, S, Zn) of the collected plant and soil samples were determined by ICP-MS and the obtained data were analyzed statistically. In soil, Ca, Fe, K and Zn values were in the optimal value whereas Al, Cu, Mg, Mn and Ni values were above the optimal values. This means that there is bioaccumulation of these heavy metals (Al, Cu, Mg, Mn and Ni) in the soil. Likewise, the concentrations of Ca, Cu, K, Mn and Zn in the plant were among the optimum values, while Al, Fe, Mg, and Ni ratios were higher than the quantification limit. The rate of these metals in the roots and other shoots of the plant are higher than in the soil. Our results showed that Senecio vernalis is a very good accumulator of Fe, Mg and Ni, and also the phytoextraction and phytoremediation ability of the plant is high.
