CAS number: 103-49-1
In order to test acute toxicity to invertebrates of the substance,
Daphnia Manga was exposed to the test solution of five nominal
concentrations of the test substance (2.5, 5, 10, 20 and 40 mg/L) and
blank control solution for a period of 48 h under static conditions.
Mobility and visible abnormalities were recorded at 24 h and 48 h. The
measured concentrations confirmed that deviation from the nominal
concentrations was less than 20 % (measured concentrations were in the
range 99.52 - 101.08 % of nominal concentrations). An EC50 of 9.7 mg/L
was determined. This toxicity study is realized according to OECD
Guideline 202 (Daphnia sp. Acute Immobilisation Test).
The study of Currenta (2011), investigating the acute toxicity of dibenzylamine in Daphnia magna according to OECD guideline 202, was considered as the key study for endpoint coverage. An EC50 of 9.7 mg/L (based on nominal test concentrations) was found after an exposure of 48 hours in a static test in freshwater.
