Geochemical processes in muddy and sandy tidal flat sediments
- 84 Downloads
Different approaches, such as element analyses of the bulk sediment and of the fine sediment fraction (<63 μm), sequential extraction techniques, correlation coefficient, and enrichment factor calculations, clearly demonstrate the differences in geochemical behavior of a muddy and a sandy sediment on the same tidal flat in the Scheldt estuary (Belgium). The geochemical processes in combination with the relatively large transport mobility of dissolved compounds due to the tidal action in the sediment, created compound specific vertical distribution profiles.
