Description of key information
Additional information
Short-term toxicity to fish:
A LC50 of 37.8 mg/L in 96 hours was determined in a test with Fathead Minnow in the presence for benzyldimethylamine (Geiger, 1986). This value is further supported by additional short term toxicity to fish studies.
Short-term toxicity to invertebrates:
The acute toxicity of benzyldimethylamine to aquatic invertebrates (Daphnia magna) was tested according to EU method C.2 'Acute Toxicity for Daphnia' (2008). No toxic effects against Daphnia magna were observed during 48 hours exposure at a limit test concentration of 100 mg/L (Currenta, 2010).
Long-term toxicity to invertebrates:
The long-term toxicity of benzyldimethylamine on aquatic invertebrates was tested in a study according to EU Method C.20 and OECD Guideline 211 in Daphnia magna. Based on the results a NOEC (21d) of 0.789 mg/L was determined for effects on reproduction and a NOEC (21d) of > 8.073 mg/L for effects on mortality.
Toxicity towards aquatic algae:
The acute toxcity of benzyldimethylamine to Algae (Desmodesmus subspicatus) was tested according to EU method C.3 'Alga Inhibition Test' (2009) yielding an ErC50(72 h) of 1.34 mg/L and NOEC(72 h) of 0.24 mg/L (Currenta, 2010).
Toxicity to microorganisms:
The effects of benzyldimethylamine to the population growth of Pseusomonas putida was determined according to Bringmann and Kühn (DIN 38412, part 8, 17 h). Benzyldimethylamine revealed an EC10 of 534 mg/L and an EC50 of 749.6 mg/L (BASF, 1987).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
