Abstract

Globalno onečišćenje okoliša teškim metalima, posebice kadmijem (Cd), predmet je brojnih istraživanja usmjerenih na pronalaženje što učinkovitijeg rješenja uklanjanja onečišćivača iz okoliša. Fitoremedijacija se pojavljuje kao nova, zelena tehnologija za in situ remedijaciju, a identifikacija autohtonih biljaka s fitoremedijacijskom potencijalom od iznimne je važnosti. U ovom je radu ispitan fitoekstrakcijski potencijal autohtone sorte kelja (Brassica oleracea var. sabauda) i kupusa (Brassica oleracea var. capitata) te promjena razine glukozinolata pri različitim udjelima kadmija (ω= 5 i 10 mg kg-1 suhe tvari tla). Određene vrijednosti za bioakumulacijski faktor (BF5mg Cd /kg =3,99 i BF10 mg Cd /kg =2,74 za kelj; BF5mg Cd /kg =4,62 i BF10 mg Cd /kg =4,22 za kupus) i translokacijski faktor (TF5 mg Cd /kg =10,68 i TF10 mg Cd /kg =10,68 za kelj; TF5mg Cd /kg =18,38 i TF10 mg Cd /kg =6,13 za kupus) te velika količina biomase upućuju da ispitivane sorte kelja i kupusa mogu biti razmatrane kao vrste s potencijalom za fitoekstrakciju onečišćenih tala kao i na potencijalan rizik po ljudsko i životinjsko zdravlje uslijed konzumacije kelja i kupusa kultiviranih na poljoprivrednim područjima s prekomjernom količinom prisutnog kadmija.

Abstract (english)

Global environmental pollution by heavy metals, especially by cadmium (Cd), attracted research efforts in finding of effective solution for the contaminated sites restoration. Phytoremediation has become an important environmental technology for in situ remediation. Thus, identification of autochthonous plant species with phytoremediation potential has received great attention recently. In this work the phytoextraction potential of autochthonous kale (Brassica oleracea var. sabauda) and cabbage species (Brassica oleracea var. capitata) and changes in glucosinolates levels in plant response to different cadmium concentrations (ω = 5, 10 mg kg- 1 of dry soil) were studied. The bioaccumulation factor values (BF5mg Cd /kg =3,99 and BF10 mg Cd /kg =2,74 for kale; BF5mg Cd /kg =4,62 and BF10 mg Cd /kg =4,22 for cabbage), translocation factor values (TF5 mg Cd /kg =10,68 and TF10 mg Cd /kg =10,68 for kale; TF5mg Cd /kg =18,38 and TF10 mg Cd /kg =6,13 for cabbage) and an increase in biomass indicated that studied kale and cabbage cultivars can be considered as the species with phytoextraction potential. The results also indicate a possible health risk to human consumption of kale or cabbage grown on the contaminated area.
