Toxicity to aquatic algae and cyanobacteria

Description of key information
A sample of diesel fuel was tested in an acute algal toxicity study using the WAF methodology and following OECD Guideline 201. The 72 -hour EL50 (loading rate resulting in 50% decrease in growth of algae) was 10 mg/L. The NOEL was 3 mg/L.
Supporting PETROTOX (version 4.01) modelled values are available. The model predicted the LL50 of the substance for P. subcapitata to be 3.40 mg/L and EL10 0.17 mg/L.
Key value for chemical safety assessment
Additional information
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.
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).
