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.

A PNECsoil for ATMP can be determined using either test data or 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.
