Description of key information
Additional information
The toxicity of the test substance on aquatic organisms was assessed for the standard aquatic trophic levels fish, Daphnia, algae and aquatic microorganisms. For Daphnia magna a short-term test has been performed in GLP compliance according to guideline OECD TG202, revealing an EC50 of 43.1 mg/L after 48 h.
The LC50 for green algae was determined in a guideline test (OECD 201) to be 65.5 mg/L. A QSAR analysis (OECD QSAR Toolbox (version 3.2.0.103) was used to predict a LC50 value of 130 mg/L of fish (Pimephales promelas).
These results demonstrates that daphnia is the most sensitive organism group when being exposed to Triacetonetriamine.
The toxicity to microorganisms was determined in a respiratory inhibition test with activated sludge according to OECD TG No. 209 in compliance to GLP. An EC50 value of 660 mg/L and an EC10 value of 370 mg/L was determined. The test substance has been shown to be not toxic up to a concentration of 180 mg/L to activated sludge of a municipal sewage treatment plant (NOEC= 180 mg/L).
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).
