Description of key information

The substance 3,5-diiodosalicylic acid is readily biodegradable in water but not readily biodegradable in sediment.

Key value for chemical safety assessment

Half-life in freshwater:
38 d
Half-life in freshwater sediment:
340 d

Additional information

The substance 3,5-diiodosalicylic acid is 50% biodegradable in water and sediment in 38 days and in 340 days respectively. This values indicates that 3,5-diiodosalicylic acid is readily biodegradable in water not readily biodegradable in sediment since the half life is more than the EPA criteria of >= 60 days (to qualify the chemical as persistent). Hence the substance is persistent in water but not in sediment.
