Geochemical regional surveys: comparative analysis of data from soils and stream sediments

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


Geochemical maps based on soils and on stream sediments were compared. It was found that the natural background for elements in the two media is quite similar. The same applies to their spatial patterns, except for P. The ratio stream sediment/soil element concentrations increases with increasing soil acidity for Ca, Cu, K, Ba, and also for Mn, Sr and Zn, suggesting that element mobilization under low pH is an important process controlling sediment composition.
