✦ Synopsis

A study was carried out of the accumulation of 45 elements in the fine-grained fraction (< 63 p,m) of the surface stream sediments of the Elbe (Labe) River. The metal contents in the sediments, compared to the geochemical background concentrations, were highest for Ag, Cd, Cu, Hg, Zn, Pb and As. Statistical factor analysis was employed to identify seven types of components in sediments with different sedimentological and.geochemical character. The eigenvalues of the first seven factors explained 85% of the total variance. Most of the contaminants in the bottom sediments appear to be bonded to hydrated Fe and Mn oxides and to particulate loading. Possible pollution sources were found by cluster analysis.

## Abstract The advective transport of algal cells into the interstices of the hyporheic zone of the River Elbe was spatially and temporally heterogenous. Even deep sediment layers were reached by large phytoplankton species. Therefore, it is suggested that (i) the advective interstitial transport
