Abstrakt: The aim of work was to evaluate the influence of the grown locality on heavy metal intake (Zn, Cu, Cr, Co, Ni, Pb and Cd) from the soil to the soybean seeds. The research was realised in five different localities of Slovakia using the same soybean cultivar (Mentor). The total content of heavy metals and their mobile forms in individual soils was compared with the limit values according to Law 220/2004 and the European Commission (2006). In all soil samples the determined total content of Cd and in one locality also the Co and Ni content exceeded maximal allowed value given by the legislative. In all soil samples the determined mobile forms of Pb, and Cd exceeded the limit values (by 50% - 140%, 2% - 17%, respectively). The measured contents of heavy metals in soybean samples were compared with the limit values given by the the Food Codex of the Slovak republic and EU Commission Regulation No. 420/2011. Only Ni and Pb amounts in seeds of soybean highly exceeded the limit value given by legislative (200-500%, and 50-100%, respectively). Despite of high soil contents of Cd the investigated soybean seeds are from the point of these risky metal contamination safe. All other determined values of heavy metal contents are lower than hygienic limits. [ABSTRACT FROM AUTHOR]
