Description of key information
In a 96-hour study potassium allophonate was not toxic to Pimephales promelas (fathead minnow) at the highest concentration tested, 93.5 mg a.i./L.
Key value for chemical safety assessment

Fresh water fish
- Effect concentration:
- 93.5 mg/L
Additional information
A 96-hour study was performed using potassium allophonate on the fish fathead minnow (Pimephales promelas) according to Organisation for Economic Co-operation and Development (OECD) Testing Guideline 203 (ABC Laboratories, 2012b). The 96-hour No Observed Effect Concentration (NOEC) was 93.5 mg a.i./L based on lack of mortality and sublethal effects at all test concentrations. The estimated 24-, 48-, 72- and 96- hour LC50s were all >93.5 mg a.i./L, the highest concentration tested. Therefore, potassium allophonate is not toxic to P. promelas at the concentrations tested.
