dandelion - Opis:
- Some trace elements, because of their high capacity for bioaccumulation, can pose a threat to the adequate development and growth of plants, animals and humans, which concerns mostly mercury (Hg) and its compounds that characterize by strong toxic properties. The aim of the research was to compare the Hg content in the Arenosols of arable fields (food plots), referred to as hunting plots, as well as in the soils of neighbouring forests. Research was performed in the Szubin Forest District (northern Poland). To assess the effect of mercury on the environment, we used dandelion (Taraxacum officinale) as a bioindicator. The samples were collected from the soil profiles from 8 hunting plots and 8 woodland areas in close vicinity of these plots. Mercury was assayed with the atomic absorption spectrometry applying the AMA 254 analyser. The mercury contamination factor (CF) and the potential ecological risk index (Er) values were determined with the local Hg value of the geochemical background (5.7 µg/kg). Assuming such very low Hg concentration as the reference value for the parent material of the soils, the mean CF value points to a considerable anthropogenic mercury accumulation in the surface horizons. The soils of hunting plots as well as forest soils are not contaminated with mercury. The total Hg content falls within the natural content level and reaches in the mineral horizons – from 3.5 to 20.7 µg/kg, while in the litter layer – from 60.3 to 166.7 µg/kg. The mercury bioconcentration factor (BCF) and translocation factor (TF) values point to a clear accumulation in the aboveground parts of dandelion. We found a significantly positive correlation between the content of mercury and organic carbon as well as the clay fraction. The mercury content in the soils under study varies and it depends on the soil origin and the effect of anthropogenic factors. In the forest soils of the Pomorze and Kujawy Province the mercury content of the geochemical background is relatively low. The areas of the Szubin Forest District do not undergo an excessive anthropopressure and sources of Hg depositions in soil surfaces can be the deposition of mercury from air.
