CAS number: 64741-56-6
A complex residuum from the vacuum distillation of the residuum from atmospheric distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly greater than C34 and boiling above approximately 495°C (923°F).
Long-term toxicity to soil macroorganisms
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
Long-term toxicity to terrestrial plants:
Short- and long-term toxicity to soil
Long-term toxicity to birds:
accordance with Column 2 of REACH Annex X, studies on long-term or
reproductive toxicity to birds do not need to be conducted due to the
existence of a large mammalian dataset.
