Group parameters for organo-halogens

These group parameters have been extensively used in water analysis. AOX was developed in Germany especially for drinking water analysis and was 

The breakdown of high AOX values is even more complicated. There is no extract left for further investigation because all of the active carbon is combusted and the polarity range of AOX is much larger than GC-MS. This is a good argument to prefer EOX over AOX for soil analysis.
