Description of key 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 estimated 96-hr LL50 value for Onchorynchus mykiss, is 45.7 mg/L.
