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.
A study was performed
to assess the effects of N,N-Dimethylbenzylamine on the reproductive
output ofDaphnia magnaSTRAUS under semi static conditions. The
study was conducted in accordance with Council Regulation (EC)
No 440/2008, Method C.20 Daphnia magna Reproduction Test (2008), which
equals in all relevant parts to the OECD Test guideline 211 (Daphnia
magna Reproduction Test; adopted: Oct. 03, 2008). Young female Daphnia,
aged less than 24 hours at the start of the test, were exposed to a
range of concentrations, nominally 0.1, 0.316, 1, 3.16 and 10 mg/L of
N,N-Dimethylbenzylamine dissolved in water. After a 21d-exposure period,
the total number of living offspring produced per parent animal alive at
the end of the test was assessed. The reproductive output of the Daphnia
exposed to the test item was compared to that of the control in order to
determine the Lowest Observed Effect Concentration (LOEC) and the No
Observed Effect Concentration (NOEC) according to Williams Multiple
Sequential t-test Procedure). Additionally, the survival of the parent
Daphnia and the time to production of first brood was determined using
Fisher`s Exact Binomial Test with Bonferroni Correction.

The results are expressed in terms of
time-weighted mean measured concentrations. Effective concentrations
ranged from 70.0% to 88.2% of the nominal values in the freshly prepared
media and from 68.4% to 84.1% in the media after 48 hours, or 72 hours
The hardness of the dilution water
used ranged from 14.2°dH to 15.8°dH (= 253.5 – 282.0 mg/L CaCO3)during
