Table 4.1.6: Degradation rates

Degradation rate in water:

Hydrolysis half-life: <12 seconds at 25°C and pH 7, for the removal of parent (measured). No significant biodegradation of the silanol hydrolysis product is expected.

Degradation rate in sediment:

No data are available regarding degradation in sediment

Degradation rate in soil:

No significant degradation in soil is expected for the silanol hydrolysis product

Degradation rate in air:

Half-life for reaction with hydroxyl radicals in air: 58.1 days for parent, 1.5 days for silanol hydrolysis product (predicted).
