EC number: 931-338-5
CAS number: 90622-77-8
Incubation time (h)
study was conducted to assess the acute toxicity of the test substance,
C12-18 and C18-unsatd. MEA, to Zebra fish (Danio rerio) according to
OECD Guideline 203 and ISO Method 7346/2 under semi static conditions.
The fish (10 per dose) were exposed to the test substance (directly
dissolved in test medium) in a concentration range of 11-90 mg/L for 96
h and immobility was determined at 96 h. No analytical dose verification
was conducted. Under the study conditions, the 96 h LC0, LC50 and LC100
were 11, 31 and 90 mg/L, respectively (Gode, 2001).

study was conducted to determine the acute toxicity of the read across
substance, C8-18 and C18-unsatd. MEA, to Rainbow trout (Oncorhynchus
mykiss) according to OECD Guideline 203 and EU Method C.1, in compliance
with GLP. Based on the results of a range-finding study, fish (10 per
group) were exposed to an aqueous dispersion of the test substance at a
concentration of 3 mg/L, the highest attainable concentration due to
limited water solubility, for 96 h under semi-static conditions. The
substance was previously dissolved in tetrahydrofuran and a solvent
control was run in parallel with the negative control and the test
substance groups. No analytical dose verification was conducted. Under
the study conditions, the nominal 96 h LC50 and NOEC were >3 and 3 mg/L,
respectively (Wetton, 1996).
