Description of key information

96-h LC50:  >746 mg/l, B. rerio (read-across)

Key value for chemical safety assessment

Additional information

There are no data for the registered substance. However, a 96-hour LC50 value of >746 mg/l has been determined for the effects of the structurally analogous read-across substance, trimethoxypropylsilane (CAS 1067-25-0), on mortality of Brachydanio rerio (new name: Danio rerio). The result was obtained under semi-static exposure conditions and it is likely that the test organisms were predominantly exposed to the hydrolysis products of the substance; propylsilanetriol and methanol.

An LC50 value of >100 mg/l has been obtained for propylsilanetriol using an appropriate calculation method (ECOSAR v.1.11).
