Description of key information

NOEC (21 d) = 10 mg/L for Daphnia magna based on reproduction (according to OECD 211)

Key value for chemical safety assessment

Additional information

As no study is available for Blankophor TP 0306 (CAS 32257 -57 -1), read-across is performed to a study conducted with the structural analogue CAS 16470 -24 -9. This GLP-study on daphnid (Daphnia magna) was conducted according to OECD 211. Daphnids were exposed in a dose-response test under semi-static conditions for 21 days (Bayer AG, Kemira, 1992). The resulting NOEC (21 d) was 10 mg/L based on reproduction. The LOEC (21 d) was 31.6 mg/L based on reproduction. For Blankophor TP 0306 comparable NOEC/LOEC-values are expected.
