Results and discussion

Any other information on results incl. tables

The fraction of organic carbon contained in the sample of sediment were ca. 1.5 %. 
A Kd of 0.013 was observed for o-toluidine, therefore the Koc can be calculated to 0.87. 
These results indicate a low sorption potential of o-toluidine onto the organic phase of soil or sediments.
