    The content of heavy metals in the alluvial formations of mountain torrent
    (2011) Florencka, Natalia
    This article presents the content of chosen heavy metals agglomerated in the sediment of bed sand-bank of the mountain torrent, taking into account the fraction volume (amount). Material was taken from several surveying points on the 1.1 km of stream length. Analyzed sediment was characterized by changeability of granulation and abundance of heavy metals. The highest content of chromium, copper, cadmium, nickel, lead and zinc was denoted in the finest fractions ( 0.025 mm), whereas the lowest amount of zinc, chromium and copper was stated in the deposit with diameter 0.5 [formula] 0.25 mm. High nickel concentration was stated in investigated alluvial material (III class of contamination), significantly higher than geological background of the sediments in Poland.
