The effect of sewage sludge application on the accumulation of Hg in plants was investigated in model pot experiments. Three soils and four crops were tested in the experiment. Hg was determined by atomic absorption spectrometer AMA-254. The highest Hg content was found in barley straw and in poppy seeds, the lowest in barley grain. Hg concentration increased by 55% on average of all growing crops in the subsequent planting period when compared to the first one.
