EC number: 265-182-8
CAS number: 64742-79-6
A complex combination of hydrocarbons obtained from a petroleum stock by treating with hydrogen to convert organic sulfur to hydrogen sulfide which is removed. It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C13 through C25 and boiling in the range of approximately 230°C to 400°C (446°F to 752°F).
Short- and long-term toxicity to soil macroorganisms except arthropods:
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are
intended for single substances and are not appropriate for the risk
assessment of this complex substance. For the purpose of risk
assessment, soil PNECs for hydrocarbon blocks have been derived using
aquatic PNECs and the equilibrium partitioning method (EqP) using
Long-term toxicity to terrestrial arthropods:
Long-term toxicity to terrestrial plants:
Short- and long-term toxicity to soil microorganisms:
Long-term toxicity to birds:
Newly hatched Mallard ducklings were fed on feed containing 0, 0.5 or 5%
No. 2 fuel oil for 18 weeks. Growth, mortality, behavioural,
histological and biochemical investigations were performed to determine
the effect of the test substance on the ducklings. Non mortality was
observed in ducklings fed no, 0.5 or 5% dietary oil. The growth NOAEL
for 18 week old mallard ducks was 5000 ppm. Growth, behavioural,
histological and biochemical effects were dose related. This study is
considered reliable as it is a non-GLP, non guideline study. It was
published in peer reviewed literature, it has minor restrictions in
design and/or reporting but is otherwise adequate for assessment.
