Description of key information

No negative effects on plants after exposure to MEA was observed.

Key value for chemical safety assessment

Additional information

In a publication by Bergmann and Eckert (1990) the effect of 2 -aminoethanol on the growth and development of barley and rye was investigated. The applied use rates resulted in a promotion of basal stem growth and an increased grain yield. In another publication by Bergmann et al. published in 1991 the effect of 2 -aminoethanol on the grain yield of barley, rye and wheat was evaluated. Again 2 -aminoethanol had a stimulating effect on grain production. Adverse effects due to the exposure to 2 -aminoethanol were not described.

 

Moreover, the test substance is not supposed to be directly applied to soil and an indirect exposure to soil is unlikely since the substance is readily biodegradable. For substances being considered as readily biodegradable, it can be assumed that they will be biologically degraded within the STP process. In special cases, if the substance is not entering the STP process but is readily biodegradable, it can be assumed that it will be rapidly biological degraded in the surface water. In both cases, a transfer to the soil compartment is unlikely.

In addition, the predicted no effect concentration (PNEC) for soil was derived from the PNEC for freshwater using the equilibrium partitioning method. Using this PNECsoil, the risk characterization revealed that the PEC/PNECsoil ratio (RCRsoil) is <1, indicating no need for further information and testing.

Therefore, no additional tests on terrestrial plants are provided.
