Applicant's summary and conclusion
- Conclusions:
- Discussion
A cut off value for logKoc of 3 is applied for adsorption potential of non-ionising substances (section R7a of the ECHA Guidance on information requirements). Paraffin Diesel Fuel components have estimated log Koc > 3. These values indicate that Diesel Fuel components are likely to be adsorbed onto soil and sediment and are not likely to leach to the ground water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
