Additional information

ATMP-xNH4will dissociate into ATMP and ammonia when it is released into soils where water is present.

ATMP and ammonia will therefore be treated separately for the purposes of deriving PNECs for soils.

Ammonia is highly soluble in water and does not accumulate in soils or in organisms. Test data for the derivation of PNECs for ammonia for the protection of soil-dwelling organisms are therefore not required.

There are no test data that can be used to derive a PNECsoil for ATMP. A PNECsoil can however be determined from the PNECaquatic by equilibrium partitioning. Any requirements for further testing will be determined on the basis of the outcome of the risk assessment conducted under Annex I.

ATMP-xNH4 will dissociate into ATMP and ammonia when it is released into soils or food where water is present. Ammonia is highly soluble in water and does not accumulate in soils or in organisms. It is therefore not necessary to obtain test data for setting a PNECsoil for ammonia. Therefore the RCR has been based on ATMP.
