Description of key information
72-hour NOELR was calculated to be 3.2 mg test item/L.
Key value for chemical safety assessment
Additional information
The influence of oil shale thermal processing residue on the growth of the freshwater green algae Pseudokirchneriella subcapitata was assessed in a static dose-response test according to OECD guideline 201 and GLP. The 72-hour EL50 value was calculated to be 82.7 mg test item/L and the 72-hour NOELR was calculated to be 3.2 mg test item/L.
