Περίληψη | Macroscale (transport and redox fronts) and microscale (mass
transfer, surface adsorption, precipitation and dissolution reactions) processes
influence the natural restoration time of heavy metal contaminated soils. The
objective of this work was to estimate the characteristic times of the various
macroscale and microscale processes that occur in heavy metal contaminated
sites and evaluate the recovery times of natural restoration. A mathematical
model developed to describe the fate, speciation and transport of heavy metals
in porous media was used to simulate the leaching of heavy metals in column
studies. The characteristic times of all the processes affecting the fate and
transport of heavy metals were determined. The leaching of heavy metals
attached to intra-granular sites was determined to be the slow mass transfer
process that controls the mobility of heavy metals in contaminated soils. The
concentration of metals (such as cadmium) at residual levels exceeded the
regulatory standards. Natural restoration of heavy metal contaminated soils to
regulatory levels may only be achieved over the span of generations. | en |
