| Popis: |
The transport behaviour of toxic metals in the subsurface is controlled by hydraulic processes and by the interactions between water and solid rock and soil materials by dissolution-precipitation, acid-base reactions, oxidation-reduction, complexation and adsorption-desorption. These processes, which have been discussed in a previous contribution (Matthess 1984a), are affected by natural organic substances. In this chapter only organo-complex formation, and sorption and desorption of toxic metals at solid organic substance affecting the mobility of toxic metals are considered. |
