72-hour EC50: >2.5 mg/l and NOEC 2.5 mg/l (nominal) (highest concentration tested) have been determined for effects of 1-methyl-N,N',N''-tris(1-methylpropyl)silanetriamine (CAS 37697-65-7) on growth rate of Pseudokirchneriella subcapitata, in compliance with OECD guideline 201. An EC50 value of >2.5 mg/l and a NOEC of 0.19 mg/l have also been determined for effects on yield of Pseudokirchneriella subcapitata.
A 72-hour EC50 value of >2.5 mg/l and a NOEC of 2.5 mg/l (nominal) (highest concentration tested) have been determined for effects of the read-across substance 1-methyl-N,N',N''-tris(1-methylpropyl)silanetriamine (CAS 37697-65-7) on growth rate of Pseudokirchneriella subcapitata. An EC50 value of >2.5 mg/l and a NOEC of 0.19 mg/l have also been determined for effects on yield of Pseudokirchneriella subcapitata. In view of the rapid hydrolysis rate of the test substance and the test preparation methods, it is likely that the algae would have been exposed to the hydrolysis products of the test substance.
It should be noted that the nominal concentration of 2.5 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.
