Description of key information

The 96hr LC50 for both freshwater and marine water fish was calculated to be >300.82 mg/l based on the effect of the acetate ion.

Additional information

The studies by Beslagic (2005) and Zok (1995) are GLP compliant and follow standard guidelines. The test substance is only 50% potassium acetate. The remainder was predominantly water with no components likely to prejudice the study outcome in relation to assessing the activity of potassium acetate. The reported NOEC and LC50 were recalculated in order to report the effect concentrations based on the concentration of the acetate ion. The NOEC and LC50 were adjusted for the molecular weight of the acetate compared to the parent molecule and also the fact that the test substance is only 50% potassium acetate.
