Additional information

A chronic toxicity study on Ceriodaphnia dubia is available for the ethylamine (CAS 75-04-7). This GLP study was conducted according to EPA Guideline 1002.0 (1989). The 7-d NOEC was determined to be 3.2 mg/L (mean measured concentration, test item purity 100%, Arkema, rep. no.: 94 -7 -5335, 1994). In this semi-static study the test solutions were renewed every 24 h. Analysis of the stability of the test concentrations resulted in measured concentrations which were in agreement with the nominal concentrations over the 24-h renewal period.
