Transfers of trace elements into testing plants (radish, triticale, spinach) have been studied in pot experiments. The results have been processed by elementary statistics, factor analysis and multiple regression analyses. The results have proven the differentiated behavior of single elements. Mn, Cd, Co, Zn and Ni are characterized by both high effective and potential mobility, pH-dependent effective mobility and transfer into plants, adjustable by liming and transfer coefficients 0.01. The hazards of uptake rates depend upon the relative toxicity and uptake rates in relation to critical plant loads. Pb and Cu have a high potential mobility and high share of organic bonds. Be, As, Cr and V have a low relative effective and potential mobility and transfer coefficients 0.01.
