Short-term toxicity to aquatic invertebrates:EC50 (24h) and EC50 (48h) > 350 mg/l for Daphnids (OECD TG 202)
The 48h acute toxicity
acid to Daphnia
magna was studied following the OECD guideline 202 under
Daphnids were exposed
during 48h to 11-aminoundecanoic acid at
nominal concentrations of 150 ; 250 ; and 350 mg/L .
concentrations (HLPC UV) were at T0 of 139.5 ; 255.4 and 350.8 mg/L and
at T48h of 152.5 ; 258.1 and 374.4 mg/L
In the test conditions no
immobilization of daphnids was observed after 24h nor 48h.
EC50 -24 and EC50
-48h > 350 mg/L
This study satisfies
the guideline requirements for an acute toxicity study with freshwater
This study is
classified as reliable without restrictions.
