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 of trimethoxysilane is not used
to fulfil any data-gap, it is used only to demonstrate that reaction of
the Si-H bond does not cause toxic effects. This data indicates that
Si-H further reactions with electrophilic compounds are not likely to
occur or do not affect short-term toxicity.
