The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Equilibrium Partitioning Method (EPM)

Due to its ready biodegradability the submission item belongs to the lowest “Soil hazard category 1” (according to ECHA R.7c, 2014, Table R.7.11-2, p 145) and thus the straight forward application of the EPM according to the TGD (ECB 2003, part II, p 112) is supported to assess the hazard and to derive the Predicted No Effect Concentrations (PNECs) for soils.

Effect data exist from non-standard studies and indicate the lower L(E)C50 of 52.7 mg/kg soil dw for terrestrial plant effects, while the nematode LC50 is reported to be 435 mg/kg soil dw.

The application of an assessment factor of 1000 according to ECHA R.10 (2008, Table R.10-10, p 41) to the lowest known L(E)C50 from terrestrial organisms, i.e. 52.7 mg/kg soil dw for plants would result in a 10 times higher PNEC than the one derived by EPM, which was therefore preferred over the actual non-standard test data for precautionary reasons.
