It was found that layer of these sediments had thickness of approx. 4 m and materials contained therein were enriched in organic matter, including humus. These sediments contained a huge amount of mechanical deposits which were dominated by building rubble that formed of 3-meter continuous rubble layer within the anthropogenic layer.}, abstract={Building rubble enriched materials in calcium carbonate and caused their alkalinisation even to level pHKCl=8.7. These deposits caused also a very clear increase of lead and zinc contents, clear increase of copper content and slightly enrichment of materials in cadmium. Not confirmed the effect of mechanical deposits on nickel content.}, abstract={The maximum content of Zn, Cu, Pb and Cd were respectively: 685, 146, 716 and 1.7 mg?kg-1. These amounts were higher than acceptable level for I group of grounds: seven times in respect of lead, twice in case of zinc according Regulation of Minister of Environment from 1 September 2016 [Dz.U. 2016 nr 0 poz. 1395].}, type={artykuł}, title={Zawartość metali ciężkich w osadach antropogenicznych z obszaru starego miasta Szczecina = Content of heavy metals in anthropogenic sediments from area of old town Szczecin}, keywords={grunty miejskie, osady antropogeniczne, zanieczyszczenia mechaniczne, uziarnienie, pH, materia organiczna, metale ciężkie, urban grounds, anthropogenic sediments, mechanical deposits, texture, organic matter, heavy metals}, }
