Toxicity to microorganisms
Administrative data
Link to relevant study record(s)
Description of key information
No toxicity studies have been carried out on microorganisms with registration substance. PETROTOX model v 4.01 predicted an LL50 of >1,000 mg/L and a EL10 of 0.95 mg/L.
QSAR predictions on toxicity to microorganisms of HFO have also been provided to support the read-across from HFO to registration substance.
Key value for chemical safety assessment
Additional information
The aquatic toxicity was estimated using the PETROTOX computer model, which 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 of >1,000 mg/L and a EL10 of 0.95 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
