Short-term toxicity to aquatic invertebrates
Administrative data

Description of key information
The toxicity to Daphnia magna was determined in a GLP-compliant guideline study (OECD 202). The EC50 (48 h) was estimated to be 43.1 mg/L based on the nominal concentrations of the test substance.
Key value for chemical safety assessment
Fresh water invertebrates

Additional information
The toxicity of the Triacetontriamine (TAT) on aquatic freshwater invertebrates was determined in a static test with Daphnia magna according to guideline OECD 202 (2004), in compliance to GLP. The study was performed over a period of 48 h with 5 concentration levels of the test substance. An influence of the pH value on the effect level could be excluded by additional testing of the highest test concentration of the test and control groups with a neutralized pH.
The effect level EC50 (24 h) was assessed to be 78.5 mg/L and the EC50 (48 h) was assessed to be 43.1 mg/L based on the nominal test concentration. The NOEC was calculated to be 12.5 mg/L. The EC50 (48 h) is used in the chemical safety assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
