CAS number: 68478-10-4
A complex combination of hydrocarbons obtained by the distillation of debenzenized light steam-cracked naphtha. It consists predominantly of cyclic olefinic and aromatic hydrocarbons having carbon numbers predominantly in the range of C8 through C16 and boiling in the range of approximately 130°C to 300°C (226°F to 572°F).
Although this endpoint can be waived
experimental data are available, so are reported here. The reported
results show that benzene has a low to moderate bioaccumulation
potential when considering data for individual organs. The highest
available BCF for whole fish were <10 for Leuciscus idus
measured by Freitag et al. (1985) and 11 for Clupea harrengus
measured by Eldridge and Echeverria (1978). These values are very
similar to the BCF of 13 calculated based on the measured log Kow of
2.13 using the equation recommended in the Technical Guidance Document
(Veith et al., 1979).
The measured log Kow of 2.13 indicates that
benzene does not exceed the screening criteria for bioaccumulation
stipulated in ECHA’s Guidance on information requirements and chemical
safety assessment - Part C: PBT Assessment (2008c). Therefore, benzene
is not considered to be bioaccumulative (B) or very bioaccumulative (vB).
