The average concentration of titanium in the alluvial soils of central Vistula was: 0.29% (ranging from 0.05-0.49) and from the Żuławy area 0.42% (ranging from 0.29-0.50), while in the clay fraction of all soils was: 0.43% (ranging from 0.29-0.49), respectively. The investigated soils contain natural amounts of titanium which can be accepted as a geochemical background. The element content correlates with the amount of particles < 0.02 and < 0.002 mm, Corg and Fe. Titanium showed little mobility in the gley soil-forming process andthebioaccumulation of the element in the humus horizons was not observed.
