Table 1. Test results
Table 2. Results of analysis of test media
Short-term toxicity to
invertebrates: 48-hour EC50 >100 mg/l
(nominal) (highest concentration tested) (OECD Guideline 202 (Daphnia
sp. Acute Immobilisation Test)). The observations in this study are
attributed to the exposure of test organisms to the hydrolysis products
in the test system. The result may be expressed in terms of
concentration of the hydrolysis product: 48-hour EC50 >85
mg/l as 3-chloropropyl(methyl)silanediol.
A 48-hour EC50 value
of >100 mg/l has been determined for the effects of the registration
substance, 3-chloropropyl(dimethoxy)methylsilane (CAS 18171-19-2, EC
242-056-0) on mobility of Daphnia magna based
on nominal test concentrations. Due to the rapid hydrolysis rate of the
test substance it is very likely that the test organisms were exposed to
the hydrolysis products of the substance rather than the parent
substance. The results may be expressed in terms of concentration of the
hydrolysis product, 3-chloropropyl(methyl)silanediol, by applying a
molecular weight correction: (MW of silanol = 154.67 / MW of parent =
182.72) * [CONCENTRATION OF PARENT = >100] = >85 mg/l.
