In the present work, we focused on monitoring the total content of heavy metals ( Cd , Pb , Cu , Cr ) in selected crops (spring barley, wheat, oilseed rape, maize and oats), grown on contaminated land in an iron-ore mining company in Spišská Nová Ves, plant Rudňany. Samples of plant material were collected at the stage of technological maturity with well-defined sampling points using the GPS. In mineralized samples we used the F - AAS on a VARIAN 240 FS performed analyzes to determine the content of heavy metals monitored. The results observed contents of risk elements point to a relatively high level of contamination of harvested agricultural production, which is used for food purposes. Exceeding the maximum levels was recorded fot Cd, Pb and Cr using the Codex Alimentarius. In the case of Cu, we exceeded HPL for each crop group recorded.
