Description of key information

Zetzsch (1991) estimates half life of the test substance on basis of the reaction constant with OH radical. The formation of OH radicals is followed in the time by analytical monitoring (capillary GC, detection limit 1 ppb).

Key value for chemical safety assessment

Half-life in air:
1 d

Additional information

The experimental data from Zetzsch (1991) is supported with 2 literature averages (Staples et al. 1997 and Tukker 1998) giving a half life in air for DEHP of 1 day.
