Description of key information

DT50 = 137 days

Key value for chemical safety assessment

Half-life in soil:
137 d

Additional information

The degradation of the test item in soil was investigated under aerobic standard conditions at 20 °C and a soil moisture of 40 % of the maximum water holding capacity. The application rate was 140 ug/kg soil.

The soil was extracted with acetonitrile + water and the extracts were analysed separately by high-performance liquid chromatography (HPLC) and mass spectroscopy (LC-MS).

The test item was degraded in soil. The DT-50 value (half-life) in the soil "Monheim 3" was calculated to be 137 days following first order reaction kinetics.
