Summary In order to investigate elemental composition of celery, and to quantify the influence of sulfur-containing N-fertilizers on the trace element uptake, a field trial with celery was carried out on marsh soil polluted with municipal wastes. The research yielded the following results: Compared to leaves at harvest time, bulbs showed significantly lower concentrations of Mo, S and Sb, but higher contents of B, Br and Cr and Cu. Since the acidifying effect of the fertilizers was suppressed by the free calcium carbonate in the soil, no significant changes in concentrations of cationic trace elements were detected in plants fertilized with ammonium sulfate compared to those which received urea or calcium ammonium nitrate. On the other hand, in these plants the conspicuous increase in total sulfur was accompanied by a significant decrease in concentrations of up to 30% for B, Br and Sb, 50% for As, 60% for Se and 80% for Mo. According to these results, in plant production on contaminated soils certain plant parts may be marketable due to their low tendency to accumulate toxic elements, and furthermore it may be feasible to reduce the contents of some of these elements in plants by the use of sulfur-containing fertilizers.
