Application of Redox Chemical Information to Predict Degradation Rates

4 Application of Redox Chemical Information to Predict Degradation Rates 

One conclusion from Fig. 15.3 is that our idea to use easily measurable parameters to predict in-situ degradation rates is not principally wrong. However, this survey has demonstrated that existing methods applied in the field studies do not provide a quantitative approach to model degradation rates. One of the major reasons that our attempt failed is the lack of reliable data. Most data sets were incomplete with respect to the relevant redox chemical parameters. In some cases not even the pH was specified 

A critical point, of course, is the reliability of degradation rates which we took from the literature. It appears that they were to some degree corrected for dilution and also groundwater transport models were applied to calculate these rates. Yet, this was not always clear and also in this case a standard procedme should be applied to make data comparable.
