Description of key information

(96-hour) LC50: >245mg/l mortality Danio rerio, reliability 2 (read-across from CAS 78-10-4).

Key value for chemical safety assessment

Additional information

There are no reliable data for the substance. However a 96-hour LC50 value of >245 mg/l and a NOEC of ≥245 mg/l have been determined for the effects of the structurally analogous substance, tetraethyl orthosilicate (CAS 78 -10 -4), on mortality of Danio rerio (tested as: Brachydanio rerio).

This read-across study is considered to be reliability 1 (reliable without restrictions); however the read across of the results is considered to be reliability 2 (reliable with restrictions).
