S-1 2003 SYMPOSIA TOPICS
   
  1. Diffusion and Diffusion-Controlled Processes in Porous Media
Diffusion processes in the gaseous, liquid and solid phases of porous media affect and often control chemical mobility and fate. For example, slow micro- and meso-scale diffusion can cause pronounced time-dependency (kinetics) in chemical sorption and biodegradation processes and will prolong remediation times at contaminated soil sites.

Transport-fate processes where diffusion plays a crucial role include (i) transport, degradation, sorption and emission of volatile organic chemicals, greenhouse gases and fumigants, (ii) aeration of soils, (iii) plant uptake processes, (iv) remediation of heterogeneous/structured porous media, (v) leaching of heavy metals and organic pollutants through soil liners, and (vi) heat transport in porous media.
This symposium (Division S1, co-sponsored by Divisions S2 and S3) is aimed at presenting state-of-the-art research on diffusion and diffusion-controlled physical, biological and chemical processes in porous media. Key subjects include but are not limited to (1) simultaneous diffusion and reactions of gaseous and dissolved compounds, (2) diffusion-controlled sorption processes, (3) diffusion effects on microbial processes, (4) measuring, describing, predicting and linking solute, gas and heat diffusivities, (5) spatial and time-scales of diffusion in the liquid, gaseous and solid phases, and (6) pore-scale diffusion processes and their effects on sorption and degradation.

Both oral and poster presentations will be featured. If you are interested in submitting a presentation to this symposium or for additional information, please contact Dr. Per Moldrup, Environmental Engineering Section, Department of Life Sciences, Aalborg University, DK-9000 Aalborg, Denmark; pm@bio.auc.dk.
