As a heavy metal, cadmium has strongly toxic effects on plants and can induce oxidative stress. It is absorbed by the roots and transported to the stems and leaves. The aim of the study was to evaluate the effect of various concentrations of cadmium on the metabolic activity of Beta vulgaris and assess the dependence of these processes on the content of metal in the plants. To demonstrate the effect of cadmium on metabolism, protein and photosynthetic pigment content, lipid peroxidation, and the activity of enzymes specific for oxidative stress in roots and shoots were measured. Seeds of B. vulgaris were treated with different concentrations of Cd supplied via a CdCl2 solution: 0 (control), 200, 300 and 400 mg/dm3. Results of the present study revealed increased GPOX activity as cadmium concentration rose, while SOD activity was stimulated by a low Cd concentration (200 mg/dm3) and reduced by high levels of Cd. Based on the present findings, it can be concluded that GPOX in B. vulgaris played a more important role in ROS scavenging than SOD did and was able to reduce the level of lipid peroxidation in plants. Cadmium, in the concentration range used, did not show any significant effect on protein or photosynthetic pigment content.

Metale ciężkie w częściach nadziemnych i podziemnych buraków ćwikłowych (beta vulgaris) w otoczeniu zbiornika unieszkodliwiania odpadów poflotacyjnych „ Żelazny Most”

W pracy zawarto zagadnienia związane z analizą obecnego wpływu składowiska odpadów Żelazny Most na zawartość metali ciężkich w burakach ćwikłowych uprawianych w ogródkach przydomowych położonych we wsiach Tarnówek i Komorniki. Z przeprowadzanych analiz zawartości Cu, Zn, Pb, Cd wynika, że spożywanie części nadziemnych i podziemnych buraków ćwikłowych może negatywnie wpływać na stan zdrowia mieszkających tam ludzi.

The work included issues related to the analysis of the current impact of the tailings pond Żelazny Most on the content of heavy metals in red beets grown in home gardens located in the villages of Tarnówek and Komorniki. Analyzes of the contents of Cu, Zn, Pb, Cd show that consumption of the above- and underground parts of rot beet may adversely affect the health of people living there.
