EC number: 292-607-4
CAS number: 90640-86-1
Distillate from the fractional distillation of coal tar of bituminous coal, with boiling range of 240°C to 400°C (464°F to 752°F). Composed primarily of tri- and polynuclear hydrocarbons and heterocyclic compounds.
No experimental data is available for the
substance distillates (coal tar),
heavy oils (anthracene oil high (> 50 ppm) BaP, AOH)
itself, but data have been identified for the closely
structure-related tar oil creosote (for read-across compare to CSR
Chapter 5.3.4. and Chapter 7.1.). For this substance, the
NOEC(28 d, collemboles) was estimated to be nominally 3.5 mg/kg soil dw,
recalculated to standard soil (3.4 % organic matter) (Bruhnke 2007). No
corresponding toxicity value for earthworm is available. Creosote caused
only transient inhibitory effects on the activity of soil microorganisms
at concentrations as high as 1000 mg/kg soil dw (nominal) (Scheerbaum
In addition, information is available for the
marker substance phenanthrene that is used to characterise the
terrestrial toxicity of AOH.
Chronic toxicity data for phenanthrene in
soil are available for annelids, collembola, plants, crustaceans, and
microbial processes. The data obtained on collembola (Sverdrup et al.,
2001, 2002) are the lowest toxicity values that are considered as
sufficient robust. Four EC10 values for Folsomia fimetaria in sandy loam
soil are available (Sverdrup et al. 2002. The difference between the
four values is the ageing of phenanthrene in the soil. The geometric
mean of these EC10 values is 18 mg/kg dw (see also EU 2008).
