Abstract research on white mustard as indicator plants were carried out in the eighth year of the long term heavy metal load experiments (Al, As, Cd, Cr, Cu, Hg, Pb, Zn) initiated in 1994 at Károly Róbert College. According to the results mercury, arsenic, and lead could not be found in the green sprouts of the plant in 2002. Hg and As quickly altered in the soil into a non-absorbable form. Lead, as indicated in previous research, remained in the roots of the plant and did not translocate into the plant organs. Data shows that the enrichment of Cd was significant. In the case of total element content we were able to prove a significant connection between the total zinc, copper, cadmium and chrome concentration of the soil and the corresponding metallic content of the plant. No significant connection could be proven between the total element content and the element content of the harvested plant with the exception of cadmium. While analysing the absorbable element content we found significant correlation between the soil’s element content and the element content of the rape sprouts in the case of aluminium and chrome. The absorbable element content and the plant’s element content at harvest did not show any significant correlation. Of the fenological and agronomical features we only examined the germinative-power (number of stems) and height. Data indicating toxicity were found only in the case of cadmium and chromium where all three treatments significantly reduced the number of mustard stems in the plots. Of the treatment combinations it was only the quality of the metals that significantly influenced the number of stems, significance could not be shown in the effects of the doses. We came to similar conclusions while examining the height of the mustard plants.
