Ocena zawarto?ci rt?ci w poziomach powierzchniowych i podpowierzchniowych intensywnie u?ytkowanych rolniczo gleb aluwialnych / Assessment of total mercury content in the surface and subsurface horizons in intensively used agricultural alluvial soils

摘要

One of the major factors determining hazard for humans, animals and plants is the increased content of trace elements in the environment. The aim of this study was to evaluate the content of mercury in surface and subsurface horizons of alluvial soils intensively used for agriculture in aspect of relationship between soil components and Hg amount bound by the soil. The results showed that there was no mercury contamination and dominant component binding this element in analyzed soils was clay fraction. The determined concentrations of mercury were close to the geochemical background level.
