Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no ecotoxicological data available for any of the streams in Category J.

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 following short-term LL50s were estimated using the PETROTOX model:

Short-term toxiticity to fish: 96-hr LL50 value for Onchorhynchus mykiss = 1.1 mg/L.

Short-term toxicity to invertebrates: 48-hr LL50 value for Daphnia Magna = 1.99 mg/L.

Toxicity to algae: 72 -hr LL50 value for Pseudokirschneriella subcapitata = 0.79 mg/l

Toxicity to microorganisms: 3 -hr LL50 value for activated sludge = 28.99 mg/l
