The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No relevant toxicity studies are available. However, as sediment RCRs are lower than 1 and log Kow/log Koc < 3, no toxicity testing is proposed for this compartment.

The EPM strategy applied to sediment follows the rules set out in the integrated testing strategy (ITS) detailed in R.7.8.12, Chapter R.7b of the ECHA Guidance on information requirements and chemical safety assessment (v1.2, Nov. 2012, pp.138-139). No adequate toxicity study is available for the evaluation of the toxicity of heptanol to sediment organisms. Therefore, the freshwater and marine sediment PNECs were derived from their respective aquatic PNECs, using the EPM. The RCRs estimated with those PNECs are lower than 1 for both compartments and no further testing is therefore required to cover the risk for both sediment compartments. This information is presented in the CSA. It has to be noted that both n-octanol/water partition coefficient (log Kow) and adsorption coefficient (log Koc) are inferior to 3. Consequently, a chemical safety assessment for the sediment compartment was not mandatory, as stated in R., Chapter R.7b of the ECHA Guidance on information requirements and chemical safety assessment (v1.2, Nov. 2012, p.140): “The main property of a substance that triggers the assessment for the sediment compartment is the potential to adsorb or bind onto sediment. As trigger value for a sediment assessment, a log Kow of 3 is proposed”. The chemical safety assessment indicates an acceptable risk (all RCRs < 1) for both sediment compartments (both freshwater and marine).
