The EVISA Link database contains information about all aspects of speciation modelling:
- speciation modelling software
- modelling of species distribution in air, water, soils and sediments
- kinetic and/or thermodynamic models

If you are looking for something special, please go to the Link Database that will allow for more specific search.
