EC number: 297-648-1 | CAS number: 93685-99-5 Oil shale waste is produced by thermal processing in a fluidized bed process at 800°C from mining exhausted oil shale. Oil shale waste consists essentially of Al2O3, CaO, CaSO4, Fe2O3 and SiO2.
Short-term toxicity to aquatic invertebrates

Description of key information
No short-term invertebrate test was conducted, because a long-term aquatic toxicity study on invertebrates is available.
Key value for chemical safety assessment
Additional information
As according to column 2, Annex VII of Regulation (EC) No 1907/2006 a short-term invertebrate test does not need to be conducted if a long-term aquatic toxicity study on invertebrates is available. The long-term invertebrate test showed a 48 h EL50 > 100 mg/L for the mortality of adult Daphnia magna exposed to water accommodated fractions of oil shale, thermal processing waste, which indicate no harmful acute toxic effect of burnt oil shale to aquatic invertebrates.
