Description of key information

Soil photolysis followed the same pattern as observed under aerobic conditions, although much slower.

The main degradation products were IR7863 (max. 30.16% AR at 15 days) and IR7825(max. 38.57% AR at 15 days).

Non-extractable radioactivity residues reached a maximum concentration at 15 days (end of the study), with 6.75% AR.

Key value for chemical safety assessment

Half-life in soil:
39 d
