EC number: 292-605-3 | CAS number: 90640-84-9 A complex combination of hydrocarbons produced by the distillation of coal tar and boiling in the range of approximately 240°C to 280°C (464°F to 536°F). Composed primarily of acenaphthene, naphthalene and alkyl naphthalene.

Additional information
No experimental data is available for creosote oil, acenaphthene fraction (wash oil) itself. Thus, information from two constituents of wash oil, the marker substance acenaphthene (see Chapter 7.1.) and the substance fluorene, is used as substitute in order to characterise long-term effects on aquatic invertebrates of wash oil.
The 7-d EC10 values concerning mortality are available for acenaphthene (marker substance) and fluorene as basic component of wash oil. The data based on measured concentrations were determined on the freshwater water flea Ceriodaphnia dubia in a semi-static test system (Bisson et al., 2000). The EC10 value of fluorene is somewhat lower (factor of ca. 0.6) than the EC10 of acenaphthene. At the same time, fluorene is present in wash oil in distinctly lower concentrations (5% compared to 15% of acenaphthene). The higher concentration of acenaphthene in wash oil is considered to counterbalance its somewhat lower toxicity. Therefore, acenaphthene is assessed to better represent the long-term toxicity of wash oil to aquatic invertebrates compared to fluorene. The EC10 of acenaphthene will serve as key value for chemical safety assessment.
No values for marine invertebrates are available.
