The mobility of potentially hazardous trace elements of the whole set of 54 representative soil units was determined. The set comprises the main soil forms and types of loads (geogenic, fluvial anthropogenic) in variants with and without pH regulation (liming). Total content (HClO4 + HF + HNO3), potentially mobilizable (0.025M Na2EDTA) and mobile species (1M NH4NO3, 0.1M CaCl2) were set up in 178 samples. Factor analysis with a very narrow (only pH and trace elements content and absolute and relative values of its mobility), standardized (additionally clay and humus) and the most extended (additionally CEC, free oxides of Fe and Al) choice of variables proved the main features of the group of the following trace elements: Mn, Cd, Co, Zn, Ni (Be).
