Absztrakt (kivonat)
Romania has large natural possibilities through Western Plain, diligence and skill of residents in cultivation and processing of specific and quality horticultural products. In the world there are few areas where the climate, soil and diversity of spontaneous and cultivated flora can provide quality natural food products, with high nutritional value. The experimental results obtained for the heavy metal concentrations in the black currants cultivated on soils close to the C.E.T. Timisoara ash storage reveal higher concentrations for these elements. Higher concentrations for the toxic heavy metals (Cd, Pb) and for the potential toxic heavy metals (Zn, Cu) were identified in some vegetables, especially for leaf vegetables and for the root vegetables. Although some heavy metals were identified in higher concentrations, close to the toxic limits or higher, the mean values for these concentrations in the vegetables were in the range of normal limits. This fact demonstrate that the pollution of this areal is incipient and forward cannot be affirm that the heavy metal pollution process is evident, but this phenomenon could be amplified in the case of a prolonged anthropic impact, and without the specific agro-pedo-ameliorative measures. The classification of the non-polluted and polluted regions is achieved by multivariate analysis (PCA-principal component analysis) of the data using especially the Fe, Mn, Zn, and Cu concentration values for the first and second principal components, and Zn and Fe concentration values for the third principal component.
