Description of key information

ATMP-xNH4 will dissociate into ATMP and ammonia in the route of administration in oral exposures (food), therefore the two substances must be assessed separately.
A NOAEL of 886 mg/kg bw/day has been determined for ammonium sulfate in a 13-week repeated-dose feeding study with male rats (diarrhea).
The value is equivalent to 228 mg/kg bw/day (ammonia).
14-day LC50 values of >565 mg/kg bw have been determined for the effects of the test substance on mortality of Mallard Duck (Anas platyrhynchos) and the Bobwhite Quail (Colinus virginianus) following dietary exposure.

Key value for chemical safety assessment

Additional information

ATMP-xNH4will dissociate into ATMP and ammonia when it is released into soils or food where water is present. ATMP and ammonia will therefore be treated separately for the purposes of deriving PNECoral.
