Additional information

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 representative structures.

Long-term toxicity to terrestrial 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 representative structures.

Long-term toxicity to terrestrial plants:

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 representative structures.

Short- and long-term toxicity to soil microorganisms:

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 representative structures.

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.
