  • Distribution of Cd, Pb, Zn, Mo and S in juvenile and mature Brassica napus L. var. napus
    Romih, Nadja ...
    The study was conducted at three locations in the Savinjska region of Slovenia, where soil is contaminated with heavy metals due to the zinc industry (Cinkarna Celje). In Ponikva the soil to a depth ... of 30 cm contains 0.8 mg kg-1 Cd, 32.2 mg kg-1 Pb and 86 mg Zn kg-1, in Medlog 1.4 mg kg-1 Cd, 37.4 mg kg-1 Pb and 115 mg kg-1 Zn and in Skofja vas 10.9 mg kg-1 Cd, 239.7 mgkg-1 Pb and 1356 mg kg-1 Zn. The pH at the selected sites was between 7.3 and 7.6. In the beginning of September 2006 two hybrids of Brassica napus L. var. napus, PR45 D01 and PR46 W31 suitable for production of biodiesel obtained from Pioneer Seeds Holding GmbH, were sown. After 96 days juvenile and after 277 days mature plants were collected. Parts of plants (root, shoot and seed) were separated and Cd, Pb, Zn, Mo and S determined by ultra-trace ICP-MS. We compared the uptake of Cd, Pb, Zn, Mo and S in different parts of juvenile and mature plants of the two different hybrids, TF (translocation factor), BAF (bioaccumulation factor) and PP (phytoextraction potential) were calculated. The mature hybrid PR46 W31 had higher shootžroot ratio and higher PP for metals (Cd, Pb and Zn) and lower PP for the micronutrient (Mo) and macronutrient (S) on the polluted site. The study demonstrated the potential use of oilseed rape on multiply polluted soils for production of 1st and 2nd generation biofuels. The potential restoration of degraded land could also disburden the use of agricultural land.
