Short-term toxicity to fish: 96-h LC50: >0.108 mg/l
(measured) (highest concentration tested) (OECD Guideline 203 (Fish,
Acute Toxicity Test)).
A 96-hour LC50 value of >0.108 mg/l has been determined for
the effects of the registration substance on mortality of Brachydanio
rerio (new name Danio rerio) based on geometric mean measured
It is likely that the test organisms were exposed to the parent
The water solubility limit of the test substance has been determined in
a separate study to be 0.02 mg/l.
A 96-hour LC50 of >100 mg/l and NOEC of ≥100 mg/l have also
been determined for the effects of the read-across substance,
trimethoxysilane (CAS 2487-90-3) on mortality of Oncorhynchus mykiss.
It is likely that the test organisms were exposed to the hydrolysis
products of the substance. Read-across from trimethoxysilane is not used
to fulfil any data-gap, but is used to demonstrate that presence of the
Si-H bond does not cause toxic effects. These data indicate that Si-H
further reactions with electrophilic compounds are not likely to occur
or do not affect short-term toxicity.
