- Conclusions:
- The most sensitive endpoint was a IC25 (reduction of dry root mass) 73mg/kg in coarse soil
- Executive summary:
The data reported here was taken from Environment Canadas fact sheet on soil quality guidelines for benzene (2004). We have been unable to obtain the original study report, so have not been able to assess the reliability of this study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
