Table 4.1.5. Degradation rates

Degradation rate in water:

Hydrolysis half-life: approximately 30 h at pH 7 and 20-25°C, for removal of parent (predicted). No significant biodegradation expected for the silanol hydrolysis product.

Degradation rate in sediment:

No data are available regarding degradation in sediment

Degradation rate in soil:

No data are available regarding degradation in soil.

Degradation rate in air:

Half-life for reaction with hydroxyl radicals in air: 0.6 days (calculated) for parent.

Half-life for reaction with hydroxyl radicals in air of silanol hydrolysis product: 0.8 days (calculated).
