Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 rainbow trout (Oncorhynchus mykiss) under semi-static conditions in a 96-hour acute test (OECD 203). The test was undertaken using water accommodated fractions. The 96hr LL50was determined to be 65 mg/L.

Supporting PETROTOX (version 4.01) modelled values are available. PETROTOX predicted the 96-h LL50of the substance for Oncorhynchus mykiss to be 8.03 mg/L.

Key value for chemical safety assessment

Additional information

Composition information, derived using two dimensional gas chromatography, has been used in conjunction with the PETROTOX model to calculate this endpoint. 

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.
