Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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

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.
