Buğday bitkisi ve toprağındaki bazı eser elementlerin bileşimi

Öz

Çinko, bakır, nikel ve mangan bitkiler için temel besin maddelerindendir. Ancak, bitkide aşırı birikmeleri tüketim sonrasında insan sağlığı açısından önemli risklere ve sorunlara yol açabilmektedir. Ayrıca, bitkilerde krom, kadmiyum ve kurşun elementlerinin birikmesi insan sağlığı üzerinde toksik etkiye sahip olabilir. Bu çalışmada, buğday bitkilerinde ve toprakta Cu, Cr, Cd, Ni, Mn, Zn, ve Pb eser elementlerinin konsantrasyonlarının belirlenmesi amaçlanmıştır. Şehir merkezinden alınan toprak örneklerinde ortalama eser element seviyeleri Mn 556.9 mg kg-1, Ni 62.45 mg kg-1, Cr 24.98 mg kg-1, Zn 40.75 mg kg-1, Cu 17.25 mg kg-1, Pb 7.65 mg kg-1, Cd 1.63 mg kg-1 olarak ve köylerden alınan toprak örneklerinde ortalama eser element seviyeleri Mn 418.7 mg kg-1, Zn 48.53 mg kg-1, Ni 32.34 mg kg-1, Cu 15.93 mg kg-1, Cr 13.7 mg kg-1, Cd 1.033 mg kg-1 olarak belirlenmiştir. Buğday örneklerinde Cd, Cr ve Pb konsantrasyonları tespit edilmemiştir. Buğday örneklerindeki ortalama Cu (4.462 mg kg-1), Mn (30.03 mg kg-1) ve Zn (20.39 mg kg-1) konsantrasyonları ise toprak örneklerine göre düşük seviyelerde belirlenmiştir. Topraktan bitkiye eser elementlerin taşınması sürecinde, bitkiler aynı koşullarda yetiştirilse bile bitkide biriken eser element seviyelerinde farklılık gösterebilmektedir.

Composition of some trace elements in wheat plant and soil

Öz

Zinc, copper, nickel, and manganese are essential nutrients for plants. However, excessive accumulation in the plant can lead to significant risks and problems in terms of human health after consumption. Also, the accumulation of chromium, cadmium and lead elements in plants can have a toxic effect on human health. This study aimed to determine the concentrations of copper (Cu), chromium (Cr), cadmium (Cd), nickel (Ni), manganese (Mn), zinc (Zn), and lead (Pb) trace elements in wheat plants and soil. Mean trace element levels in soil samples taken from the city center Mn 556.9 mg kg-1, Ni 62.45 mg kg-1, Cr 24.98 mg kg-1, Zn 40.75 mg kg-1, Cu 17.25 mg kg-1, Pb 7.65 mg kg-1, Cd as 1.63 mg kg-1 and the average trace element levels in soil samples taken from villages Mn 418.7 mg kg-1, Zn 48.53 mg kg-1, Ni 32.34 mg kg-1, Cu 15.93 mg kg-1, Cr 13.7 mg kg-1, Cd 1.033 mg kg-1 was determined. Cd, Cr, and Pb concentrations were not detected in wheat samples. Average Cu (4.462 mg kg-1), Mn (30.03 mg kg-1), and Zn (20.39 mg kg-1) concentrations in wheat samples were determined at lower levels compared to soil samples. In the process of transporting trace elements from the soil to the plant, even if the plants are grown under the same conditions, the trace element levels accumulated in the plant may differ.
