Description of key information
Additional information
Short-term toxicity
Acute aquatic toxicity has been examined in fish, daphnia and alga (OECD TG 203, 202, and 201, respectively), in daphnia under static sealed/closed and largely open conditions, while for fish (semi-static) and alga (static) the test conditions were open.
The lowest acute toxicity value was obtained under closed test conditions of a daphnia study: LL50(48 h) = 22.4 mg/L (anthracene oil CS 06). Under open conditions, the corresponding values in daphnia were approximately 6 and 8 times higher: LL50(48 h) = 137 mg/L (anthracene oil CS 07) and 167 mg/L (anthracene oil CS 06).
These findings indicate that volatility of constituents in anthracene oil is substantial and that volatile components contribute to acute intoxication. It may be assumed that narcosis is the main underlying mechanism for the high intoxication by the volatile fraction.
All other toxicity data in fish and alga are significantly above 10 mg/L or 100 mg/L (based on loading):
Alga: EL50(72 h) = 25 mg/L (CS 07) and 48 mg/L (CS 06)
Fish: LL50(96 h) > 100 mg/L (CS 06)
Inhibitory effect micro-organisms:
A structure-related tar-oil caused no substantial inhibition of a mixed microbial population but at high nominal concentrations (EL50 = 670 mg/L, OECD TG 209).
Long-term toxicity
No data are available for anthracene oils.
Phenanthrene, selected as key marker substance, produced chronic toxicity in freshwater and marine organisms within its water solubility range: The lowest NOEC values identified were 11 µg/L (estimated, in fish), 13 µg/L (analytical, in daphnia) and 26 µg/L (analytical, in alga).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
