is a hydrocarbon UVCB, meaning that its composition is variable and the
exact proportions of individual components are not known. Hence,
derivation of a PNEC using conventional methods of applying assessment
factors to toxicity data are not appropriate. Instead, the hydrocarbon
block method is used for environmental risk assessment (see REACH
guidance, R7, app.13-1). See Product Library tab in “assessment report.
PetroRisk information excel” spreadsheet attached to Section 13 for PNEC
values. Aquatic PNECs for hydrocarbon blocks have been derived using the
HC5 statistical extrapolation method and the target lipid model using
representative structures. Given the large database of organisms
included in the target lipid model, an assessment factor of one has been
applied to the HC5. Therefore, it is not possible to identify a single,
representative PNEC for this complex substance.
Aliphatics (≤2% aromatic) are
not classified for the environment.
