Description of key information

Table. Degradation rates

Degradation rate in water:

Hydrolysis half-life: 1.1 hours at pH 7 and 20-25°C (predicted), for removal of parent. No significant biodegradation of silanol hydrolysis product expected.

Degradation rate in sediment:

No significant biodegradation of silanol hydrolysis product expected.

Degradation rate in soil:

No significant biodegradation of silanol hydrolysis product expected.

Degradation rate in air:

Half-life for reaction with hydroxyl radicals in air: 5.7 days for parent; 1.5 days for silanol hydrolysis product (predicted).
