Description of key information

EC50 (3 h) > 10000 mg/L based on respiration rate (according to OECD 209)

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 was conducted according to the guideline "EG L133 Teil C" and equivalent to OECD 209. Activated domestic sludge was used for the test. Test duration was 3 h (Bayer AG, Kemira, 1999). The resulting EC50 (3 h) was > 10000 mg/L based on respiration rate. 

Thus, for Blankophor TP 0306, no effects on algae are expected.
