Abstract

The concentration levels of ten different heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn) were investigated in the soils and the edible parts of six different cultivated plants (Brassica oleracea var. capitata, Portulaca oleracea, Vitis vinifera, Raphanus sativus, Phaseolus vulgaris, and Vigna unguiculata subsp. unguiculata) from the Isparta region in southern Turkey, where volcanic soils are present. The heavy metal content of the samples was determined by ICP-AES (Inductively Coupled Plasma Atomic Emission Spectrometer) and plant translocation factors (TF) were also calculated. Both soil and plant samples had significant differences in heavy metal concentrations. The mean heavy metal contents in soil samples decreased in the order of Fe>Mn>Zn>Cu>Pb>Mo>Ni>Cr>Cd>Co. The concentrations of Cd and Pb exceeded their respective permissible limits in soil samples; however, their accumulation in plants was lower due to the physical and chemical properties of the soils, which prevented their translocation to the plants. The TF values of Mo are highest in all plants except P. oleracea and the Mn concentration is highest in P. oleracea. Comparisons of the present results to those of others in related literature indicated that only Mn was above

土耳其南部火山地区一些栽培植物可食用部分和培养基样品中的重金属积累

研究了6种不同栽培植物(芸苔、马齿苋、葡萄、莴苣、菜豆和荆芥)土壤和可食部位10种重金属(Cd、Co、Cr、Cu、Fe、Mn、Mo、Ni、Pb和Zn)的浓度水平。来自土耳其南部的伊斯帕塔地区，那里有火山土壤。采用电感耦合等离子体原子发射光谱仪(ICP-AES)测定了样品中的重金属含量，并计算了植物转运因子(TF)。土壤和植物样品中重金属含量差异显著。土壤样品中重金属平均含量依次为Fe>Mn>Zn>Cu>Pb>Mo>Ni>Cr>Cd>Co。土壤样品中Cd、Pb含量均超过允许限量;然而，由于土壤的理化性质，它们在植物体内的积累量较低，阻碍了它们向植物的转运。除马鞍草外，所有植物中Mo的TF值最高，Mn浓度在马鞍草中最高。与其他相关文献的结果比较表明，只有Mn高于

期刊介绍： Cessation. Ekoloji is an international journal that focuses on papers that report results from original research on all disciplines engaged in the field of environmental research. We welcome articles that cover the entire spectrum of environmental problems and environmental pollutants, whether chemical, biological or physical. Its coverage extends to all environmentally related issues: air and water pollution, solid waste, noise, recycling, natural resources, ecology and environmental protection. It includes articles on basic and applied environmental pollution research, including environmental engineering and environmental health. All types of pollution are covered, including atmospheric pollutants, detergents, fertilizers, industrial effluents, metals, mining wastes, oil, pesticides, plastics, radioactive materials and sewage. It also includes research papers on ecological and environmental issues such as climate change, biodiversity. The primary criteria for publication are scientific quality and ecological/environmental significance. The journal will be read and contributed to by biologists, applied ecologists, environmental scientists, natural resource specialists, environmental engineers, environmental health specialists, agro-ecologists, veterinaries, agricultural engineers, landscape planners and designers. The journal welcomes full "research papers" and short "research notes", only in the English language.
