In Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), it is suggested, that "in the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment. In particular for substances that have a high potential to adsorb to soil or that are very persistent, the registrant shall consider long-term toxicity testing instead of short-term.These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely."

For ammonium carbamate there are no appropriate data on terrestrial toxicity available for a derivation of PNECsoil. The substance however, exhibits low potential for adsorption and is not bioaccumulative. Furthermore, results of aquatic tests revealed only little harmful effects of ammonium carbamate, and by thereby suggesting little hazardous potential towards soil organisms. Therefore, the equilibrium partitioning method has been used to assess the hazard potential of ammonium carbamate towards soil organisms.
