Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Administrative data

Endpoint:
short-term toxicity to aquatic invertebrates
Type of information:
(Q)SAR
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:

Episuite is a well known QSAR software package that is widely used and accepted by both industry and regulatory authorities.
Trimethylvinylsilane is considered to be inside the applicability domain of the EpiSuite ECOSAR model since the following criteria are fulfilled (as described in the model's manual):
- The molecular weight of trimethylvinylsilane is within the molecular weight range of the training set
- Trimethylvinylsilane is within the log Kow range of the training set
