PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB
Justification:

Persistence Assessment

Based on the structure in Benzyldimethylamine no hydrolysable groups are present. The substance can thus be regarded as hydrolytically stable.

Benzyldimethylamine was shown to be 100 % inherently biodegradable after 13 days and to 70% within 7 days and thus fulfilled the criterion for inherent, ultimately biodegradability (BASF, 1987).

Thus, Benzyldimethylamine was not considered persistent.

Bioaccumulation Assessment

Benzyldimethylamine was determined to be none or not highly bioaccumulative. The BCF at a concentration of 500 µg/L is 2.1 to 6.4, and at a concentration of 50 µg/L the BCF is < 6.2 to 22 (MITI-Online, MITI-Buch, 1992).

Thus, Benzyldimethylamine was not considered bioaccumulative.

Toxicity Assessment

Based on the results of the toxicity assessment, Benzyldimethylamine does not fulfil the toxic criterion as the NOEC in Daphnia and algae was determined to be > 0.01 mg/l.
