NOEL (48 h) = 2 mg/L (Daphnia)

Key value for chemical safety assessment

Additional information

Two studies conducted according to OECD 202 guideline are available on the acute toxicity to Daphnia for hydrocarbons, C6-C7, n-alkanes, isoalkanes, cyclics, <5% n-hexane (Shell 1994, 1995). The acute toxicity, as measured by immobilisation to Daphnia, was evaluated in freshwater by using water accomodated fractions (WAFs). Under the conditions of these studies, the test substance, hydrocarbons, C6-C7, n-alkanes, isoalkanes, cyclics, < 5% n-hexane, produced acute toxicity to Daphnia at 3 mg/L (Shell 1994) and 10-22 mg/L (Shell 1995) based on nominal loadings of the test substance in water.
