A study on possible use of (common nettle) plants as uranium (U, U) contamination bioindicator near phosphogypsum stockpile.

The aim of this study was to determine uranium concentrations in common nettle () plants and corresponding soils samples which were collected from the area of phosphogypsum stockpile in Wiślinka (northern Poland). The uranium concentrations in roots depended on its concentrations in soils. Calculated BCF and TF values showed that soils characteristics and air deposition affect uranium absorption and that different uranium species have different affinities to . plants. The values of U/U activity ratio indicate natural origin of these radioisotopes in analyzed plants. Uranium concentration in plants roots is negatively weakly correlated with distance from phosphogypsum stockpile.
