Samenvatting

A novel Diffusive Gradients in Thin Film (DGT) probe is developed consisting of a diffusive AgI gel layer and a back-up microchelex resin gel layer. 2D high resolution images of sulphide and trace metals were determined respectively on the AgI gel by densitometric analysis and on the microchelex resin layer with Laser Ablation (LA)-ICPMS.
The validity of the analytical procedures used for the determination of sulphide and trace metals has been investigated: low RSDs on replicate measurements, linear trace metal calibration curves between the LA-ICP-MS signal and the true trace metal concentration in the resin gel and a good agreement of the sulphide results obtained with the AgI resin gel and with other analytical methods were found.
The method was applied on anoxic sediment pore waters in an estuarine and a marine system. Simultaneous remobilisation of sulphide and trace metals was observed in the marine sediment
