EC number: 265-198-5
CAS number: 64742-94-5
A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).
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 Onchorhynchus mykiss, is 1.1 mg/L.
Supporting data on Toluene and Ethylbenzene, two constituents in
Category J were used to support the QSAR prediction. Experiemental 96
-hour LC50s of 5.5 and 8.4 mg/L (for toluene and ethylbenzene,
respectively) have been reported.
