( ) between brackets: number of daphnia observed trapped at the surface of the test solutions. These organisms were reimmersed into the respective solutions before recording of mobility.
48-hour EC50: >3.75 mg/l (nominal) (highest concentration tested) has been determined for effects of 1-methyl-N,N',N''-tris(1-methylpropyl)silanetriamine (CAS 37697-65-7) on mobility of Daphnia magna, in compliance with OECD guideline 202.
A 48-hour EC50 value of >3.75 mg/l (nominal) (highest concentration tested) has been determined for effects of the read-across substance 1-methyl-N,N',N''-tris(1-methylpropyl)silanetriamine (CAS 37697-65-7) on mobility of Daphnia magna. No effects were observed in the test. In view of the rapid hydrolysis rate of the test substance and the test preparation methods, it is likely that the Daphnia would have been exposed to the hydrolysis products of the test substance.
It should be noted that the nominal concentration of 3.75 mg/l tested was considered higher than the maximum soluble concentration in test medium, therefore there is no gap between maximum soluble concentration and the highest test concentration.
See the ecotoxicological discussion for further details on the test substance and justification of read-across.
