Additional information

The long-term effects of oil shale thermal processing residue to aquatic invertebrates were evaluated in a long-term test (21 d) with Daphnia magna according to the OECD 211 and GLP. The 21‑day NOELR was determined to be 1.0 mg test item/L for the reproduction rate and 32 mg test item/L for the survival of the adult test animals, respectively.
