Özet
Kirletilmiş toprakların fiziksel ve kimyasal yöntemlerle kirliliklerinin giderilmesi, ekonomik olarak yüksek maliyetlere neden olduğundan bunlara alternatif daha doğal ve ekonomik uygulamalar vardır. Çevredeki canlıların hayatlarına önemli boyutlarda toksik etki oluşturan ağır metaller, en birincil ve tehlikeli maddelerden birini oluşturmaktadır. Ağır metal toksisitesinin temizlenmesinde ve kirli toprakların kirliliğinin gideriminde fitoremediasyon tekniği uygulanmaktadır. Bu çalışma Cr ağır metali ile kirletilmiş toprakların fitoremediasyon tekniği ile temizlenmesinde kullanılabilirliği araştırılmıştır. Fitoremediasyon yöntemi kullanılarak krom ağır metali ile kirletilmiş topraklarda mısır bitkisinin hiperakümülatör bitki olup olmadığı incelenmiştir. Krom ağır metalinin çözünürlüğünü artırmak amacıyla topraklara farklı miktarlarda şelat verilerek, mısır bitkisinin Cr elementini temizleme başarısı değerlendirilmiştir. Deneme tesadüf blokları deneme planına göre kontrollü şartlarda 3 tekrarlı, 3 kontrol saksısı ve 5 şelat dozunda (0, 10, 20, 40, 80 mmol/kg) 18 saksıda yürütülmüştür. Saksılardaki topraklara 30 mg/kg CrO3 verilerek 30 gün inkübasyona bırakılmıştır. Saksılara 150 mg/kg N, 100 mg/kg P, 125 mg/kg K ilavesi mısır tohumlarının ekimleri ile beraber uygulanarak ihtiyacına göre sulamaları yapılıp gelişimlerine bakılmıştır. Bitkilerin büyüme sürecinde hasat yapılarak gövde ve kök aksamında krom içeriği sırasıyla kontrol 2,81 mg/kg iken 80 mmol/kg EDTA şelatı uygulanan dozda 31,46 mg/kg bulunmuştur. Bu durum istatiksel olarak % 5 düzeyinde önemli olduğu tespit edilmiştir. Bitkinin kök aksamında krom içeriği ise kontrolde 18,57 mg/kg olarak tespit edilirken en yüksek şelat uygulanan dozda ise 34,95 mg/kg olarak bulunmuştur. Bu araştırma ile Cr(VI) ile kirletilmiş toprakların temizlenmesinde ekonomik ve uygulanabilir bir yöntem olan fitoremediasyon yönteminde mısır bitkisinin hiperakümülatör bitki olduğu ortaya konulmuştur.
Removal of contaminated soils by physical and chemical methods, as they cause high costs. There is more natural and economic applications alternative to these. One of the most primary and dangerous substances create, significant dimensions to the lives of living beings heavy metals forming toxic effects. Phytoremediation technique is used to cleaning of heavy metal toxicity and removes the pollution of polluted soils. This study was carried out the usability with the phytomediation technique of the soil contaminated with Cr metal. Using the phytoremediation method, it is investigated whether corn plant are hyperacumerator plants in soils contaminated with chromium heavy metal. In order to increase the solubility of the chromium heavy metal, chelate is given to the soil in different amounts and the success of cleaning the Cr element of corn plant has been evaluated. Cr element was given to soil and phytoremediation were determined using corn plant. In order to increase the content of phytoremediation, chelate is given to soil in different amounts and the success of cleaning the Cr element of corn plant has been examined. Trial random blocks according to the trial plan, the experiment was carried out in 18 pots with 3 replicates and 5 chelate doses (0, 10, 20, 40, 80 mmol/kg) in controlled conditions according to the trial plan according to full chance. 30 ppm CrO3 was given to the soil in pots and incubated for 30 days. 150 mg/kg N, 100 mg/kg P, 125 mg/kg K is added to the pots corn seeds are applied together with the planting according to the needs of the irrigation has been made. In the growth process of the plants by harvesting, respectively the chromium content of the stem and root parts was 2,81 mg/kg, while 80 mmol/kg of EDTA chelate was 31,46 mg/kg. This was statistically significant at 5 % level. The chromium content of the plant was determined as 18,57 mg/kg in the control, whereas the highest chelate was 34,95 mg/kg. In this research, it has been shown that corn plant is a hyper accumulative plant in phytoremediation method which is an economical and applicable method for cleaning soil contaminated with Cr(VI).
