24 mg/L

Additional information

Measured data were not available for dichloro(diphenyl)silane (80-10-4) for short term toxicity to aquatic invertebrates. Due to the rapid rate of hydrolysis, measured data for the hydrolysis product diphenylsilanediol (947-42-2) was considered appropriate to use to determine the toxicity of the substance. A 48-hour EC50 value of 24 mg/l has been determined for the effects of the test substance on mobility/mortality of Daphnia magna based on mean measured concentrations according to OECD guideline 202 (Wildlife international 2004b). The study is considered reliable and was selected as key. These values are supported by a QSAR calculated 48 hr LC50 of 17.9 mg/l.
