Additional information

Biodegradation in water: screening tests:

The substance diiodohydroxyquinoline is 50% biodegradable in water in 38 days (half-life). This value indicates that diiodohydroxyquinoline is readily biodegradable in water since the half life is less than the threshold criteria of >= 60 days (to qualify the chemical as persistent).

Hence, it can be concluded that the substance diiodohydroxyquinoline is not persistent in water.

Biodegradation in water and sediment: simulation tests:

The substance diiodohydroxyquinoline is 50% biodegradable in water and sediment in 38 days and in 340 days respectively. This values indicates that diiodohydroxyquinoline is readily biodegradable in water while is not readily biodegradable in sediment according to the threshold criteria of >= 60 days (to qualify the chemical as persistent).

Hence, it can be concluded that the substance diiodohydroxyquinoline is not persistent in water while it is persistant in sediment.

Biodegradation in soil:

The substance diiodohydroxyquinoline is 50% biodegradable in soil in 75 days (half-life). This value indicates that diiodohydroxyquinoline is not readily biodegradable in soil since the half life is more than the threshold criteria of >= 60 days (to qualify the chemical as persistent).

Hence, it can be concluded that the substance diiodohydroxyquinoline is persistent in soil.
