Description of key information
Toxicity of NExBTL renewable diesel (a UVCB substance of similar composition to the substance) toward micro-organisms (activated sewage sludge) was determined in a GLP compliant laboratory study according to OECD Guideline 209 (Activated sludge, respiration inhibition test). No effects on respiration were observed at the test concentration of 1,000 mg/L. These results are also supported by PETROTOX (version 4.01) which gave a predicted values of an LL50 and a EL10 of >1,000 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 1 000 mg/L
- EC10 or NOEC for microorganisms:
- 1 000 mg/L
Additional information
PETROTOX combines a partitioning model (used to calculate the aqueous concentration of hydrocarbon components as a function of substance loading) with the Target Lipid Model (used to calculate acute and chronic toxicity of non-polar narcotic chemicals). PETROTOX computes toxicity based on the summation of the aqueous-phase concentrations of hydrocarbon block(s) that represent a petroleum substance and membrane-water partition coefficients (KMW) that describe the partitioning of the hydrocarbons between the water and organism.
The model predicted an LL50 and a EL10 of >1,000 mg/L.
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).
