The aquatic toxicity was estimated using the
Petrotox computer model (PETROTOX-UDM_ver3.01-2006-01438-01-E), 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 hydrocarbon substance and
membrane-water partition coefficients (KMW) that describe the
partitioning of the hydrocarbons between the water and organism. The
hydrocarbons, C14-C16, n-alkanes, isoalkanes, <2% aromatics, estimated
protozoan, Tetrahymena elliotti, 48-hr EL50 value is
>1000 mg/L based on growth inhibition.
.The registered substance is a complex
petroleum UVCB whose constituents have variable physicochemical
properties. Therefore, a modeling framework is needed to account for the
bioavailability of the constituents in the mixture, which was then used
to predict the toxicity of the substance as a whole. The target lipid
model (TLM) and HC5, have been applied and modeled data are considered
fit for purpose.
Detailed information covering the
calculation model, compositional data used as input, validity,
applicability and adequacy of the result are attached in section 13.2 of
The hydrocarbons, C14-C16, n-alkanes,
isoalkanes, <2% aromatics, estimated protozoan 48-hr EL50 value
is >1000 mg/L based on growth inhibition of Tetrahymena elliotti.
