Description of key information

No long term invertebrate toxicity data are available. The  chronic toxicity to Daphnia magna was predicted using the Petrotox model and the chronic NOEL was estimated at 0.51mg/l.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
0.51 mg/L

Additional information

The chronic toxicity to Daphnia magna 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 chronic toxicity NOEL (No Observed Effect Level) value for Daphnia magna is 0.51 mg/L based on mortality.
