“…The stabilization of metals was assessed using toxicity levels characteristic of the leaching procedures associated with municipal solid waste treatment, and revealed values lower than a quantified limit, therefore characterizing this biochar as safe for disposal. Phytoremediation experiments on mixed Cd, Pb, and Zn contaminated sludge and soil with the biomass of B. rapa in the presence of an EDTA chelating agent showed a similar trend [145]. After pyrolysis, most of the metal content was concentrated in the solid product: 98.8% for Pb, 97.9% for Cd, and 97.5% for Zn.…”

The genus Brassica is recognized for including species with phytoaccumulation potential and a large amount of research has been carried out in this area under a variety of conditions, from laboratory experiments to field trials, with spiked or naturally contaminated soils, using one- or multi-element contaminated soil, generating various and sometimes contradictory results with limited practical applications. To date, the actual field potential of Brassica species and the feasibility of a complete phytoextraction process have not been fully evaluated. Therefore, the aim of this study was to summarize the results of the experiments that have been performed with a view to analyzing real potentials and limitations. The reduced biomass and low metal mobility in the soil have been addressed by the development of chemically or biologically assisted phytoremediation technologies, the use of soil amendments, and the application of crop management strategies. Certain issues, such as the fate of harvested biomass or the performance of species in multi-metal-contaminated soils, remain to be solved by future research. Potential improvements to current experimental settings include testing species grown to full maturity, using a greater amount of soil in experiments, conducting more trials under real field conditions, developing improved crop management systems, and optimizing solutions for harvested biomass disposal.

“…Sonuç olarak, bu çalışmada Cd ile kirlenmiş topraklarda, toprağı herhangi bir yere taşımadan yerinde kanolayla yapılacak fitoremediasyon çalışmasının oldukça etkin olacağı ortaya konmuştur. Model çözeltilerle hazırlanan toprakta gerçekleştirilen çalışmaların uygulanabilirliğini araştırmak üzere aynı bitkilerle gerçekleştirilen çalışmada da yine kanolanın arıtım için en uygun bitki olduğu belirlenmiştir [29]. Ülkemizde, ağır metallerle kirlenmiş sahaların temizlenmesinde bu çalışmadaki yönteme benzer bir yolun izlenmesi hem maliyet hem de atıktan faydalı ürünler elde edilmesi açısından çok önemli katkılar sağlayacaktır.…”
