Description of key information

laboratory half-life (20 °C): 9.1 day (median, n=11)
field half-life: 8.2 days (median, n=13)

Key value for chemical safety assessment

Additional information

Half-life values have been determined in several laboratory and field studies. The experimental data have been re-modelled using ModelManager software using Simple First Order (SFO) and First Order Multi-Compartment (FOMC) kinetics.

The re-modelled half-lives, superceding those described in the original test reports, ranged between 2.3 and 38.4 days. Out of 11 soils the new median of the laboratory half-lives was 9.1 days. Out of 13 soils the new median of the field half-lives was 8.2 days. The kinetics data used for the evaluation were obtained by testing either the R-enantiomer or the racemate.
