Abstract

Cadmium (Cd), lead (Pb) and zinc (Zn) contaminations of soils are a serious worldwide problem thataffects human health and environmental quality. Phytoremediation, use of green plants to remove, sequester ordetoxify contaminants, offers an environmentally friendly alternative solution for soil remediation. The effect ofcanola (Brassica napus L.) and a biodegradable chelate, ethylenediamine dissuccinate (EDDS), were tested onremediation of multi metal (Cd, Pb, and Zn) contaminated soil. In the pot experiment, plants were grown for twomonths on five soil mixtures obtained by mixing an uncontaminated soil sample with 0, 25, 50, 75, and 100% ofmultiple metal contaminated soil. The biomass of the plants were weighed, and the uptakes of Cd, Pb and Zn inthe shoot were determined using ICP-MS. The addition of multi metals to the soil led to the increase of multimetal contents in plants. Consequently, the dry weights of the plants were increased with EDDS treatments in25 and 50 % multi-metal doses compared to the control treatment. EDDS has significantly increased the uptakeof metals (Cd, Pb, and Zn) from the soil and their accumulations in shoots of the plants. The Cd concentrationof plant was higher than the hyperaccumulation limit of Cd (>100 mg kg-1) with EDDS treatment in 25 and 50%multi-metal doses (141 and 174 mg Cd kg-1, respectively) except for Zn and Pb concentrations.

Özet

Toprakların kadmiyum (Cd), kurşun (Pb) ve çinko (Zn) ile kirlenmesi insan sağlığını ve çevre kalitesini etkileyen dünya çapında ciddi bir sorunudur. Fitoremediasyon, bitki kullanılarak kirleticilerin uzaklaştırılması, giderilmesi veya detoksifiye edilmesi yöntemi, toprakların ıslah edilmesinde çevre dostu alternatif bir çözüm sunar. Bu çalışmada, biyo-bozunabilir bir şelat olan etilendiamin disüksinatın (EDDS) kanola (Brassica napus L.) ile çoklu-metal (Cd, Pb ve Zn) ile kirlenmiş bir toprağın fitoremediasyonu üzerindeki etkisi araştırılmıştır. Saksı denemesinde, kanola bitkileri çoklu metallerle kirlenmiş toprağın temiz toprakla karıştırılmasıyla elde edilen beş toprak karışımı (%0, %25, %50, %75 ve %100) toprakta iki ay süreyle yetiştirilmiştir. Bitkilerin biyokütleleri tartıldı ve yeşil aksamın Cd, Pb ve Zn alımları ICP-MS kullanılarak belirlenmiştir. Toprağa çoklu metallerin eklenmesi, tüm bitkilerde çoklu metal içeriklerinin artmasına neden olmuştur. Sonuç olarak, kontrole kıyasla bitkilerin kuru ağırlıkları % 25 ve % 50 çoklu metal dozlarında EDDS uygulaması ile artmıştır. EDDS, topraktan metallerin (Cd, Pb ve Zn) alınmasını ve bitkinin yeşil aksamında birikmesini önemli ölçüde artırmıştır. Bitkinin, Zn ve Pb konsantrasyonları hariç EDDS uygulaması ile Cd konsantrasyonu % 25 ve % 50 multimetal dozlarında sırasıyla 141 ve 174 mg Cd kg-1’e ulaşmıştır. Bu değer Cd hiperakümülasyon sınırından (
