Description of key information
The acute toxicity for daphnia was determined in a study according to EC-Method C.2 resp. OECD 202 (2004). The test medium was prepared according to OECD Guidance 23 (difficult substances) as water accommodated Fraction.
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
In a valid GLP study following Guideline EC-Method C.2 and OECD 202 (2004) the short term toxicity of phenothiazine to aquatic invertebrates, represented by Daphnia magna was determined.
According to the results of the test, the EC50(48 h)of the test item was determined to be 11.92mg/L(nominal). The corresponding NOEC (48 h)was 4.27 mg/L(nominal). The corresponding actual values based on the chemical analysis of the test item in the media were 0.154 mg/L for theEC50(48 h) and 0.0621mg/L for the NOEC (48 h). The substance is classified as very toxic to daphnia.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
