Abstract

 The content and profile distribution patterns of Cu, Ni and Zn in Histosols of headwater peatlands were studied in the valley of Kamienna Creek – left bank tributary of Słupia River. The soils were sampled every 10 cm up to mineral bed. The content of metals was analyzed with microwave plasma atomic emission spectrometry method after digestion of samples in a mixture of concentrated HNO3 and 30% H2O2. The content of Cu ranged from 6.0 to 14.4 mg·kg-1, Ni from 4.3 to 31.8 mg·kg-1 and Zn from 2.4 to 67.5 mg·kg-1. The observed contents were within natural for organic soils in Poland. Three factors play a predominant role in the shaping the contents and profile distribution patterns of Cu, Ni and Zn in the investigated soils – 1) contribution of organic matter and mineral fractions in peat mass, 2) the influence of past and contemporary plant communities, which is realised especially by metals uptake by roots and their return to the soil as components of litterfall, throughfall and stemflow, and 3) permanent, one-way flow of groundwaters through soils, which is especially intense in horizons located above mineral bed. This flow, on the one hand can lead to enrichment in ionic forms of metals, but on the other hand can contribute to the leaching of their labile forms. Vertical distribution patterns of Cu, Ni and Zn in the investigated soils suggest predominance of leaching over enrichment.
