study was conducted to determine the acute toxicity of the read across
substance, C8-18 and C18-unsatd. MEA, to Daphnia magna
according to OECD Guideline 202, in compliance with GLP. Daphnia (20 per
group) were exposed to the read across substance (directly dispersed in
water) at concentrations of 0.10-10 mg/L for 48 h under static
conditions. Immobility was determined at 24 and 48 h. No analytical dose
verification was conducted. Under the study conditions, the nominal 48 h
EC50 and NOEC were 3.0 and 1.8 mg/L, respectively (Wetton, 1996).
