Description of key information
The following information is available for the short-term acute toxicity to fish endpoint:
Steger-Hartmann T. & Wendt B. (1998) Acute toxicity of di-n-butyltin oxide (ZK 26385) to the Zebra fish Danio rerio. Testing laboratory: Schering AG, Experimentelle Toxikologie. Report no.: IC19. Owner company: Schering AG Report date: 1998-12-11.
The Steger-Hartmann and Wendt study, as a stand alone study it is a relaibility 1, however as it is used for read-across purposes, the study has been assigned a reliability 2 (reliable with restrictions). The data presented is on the substance dibutyltin oxide.
Key value for chemical safety assessment
Additional information
From the Steger-Hartmann T. & Wendt B. (1998) study, a LOEC of 3.1 mg/L was determined.
Read-across from dibutyltin oxide to dibutyl dimethoxystannane concerning aquatic toxicity endpoints was considered appropriate as dibutyltin and octyltins are known to hydrolyse rapidly in water (as presented by Yoder 2003, under the data requirement hydrolysis), and form, in the case of dibutyltins, dibutyltin oxide.
Due to the similarity between these the test substance and registration substance, it is considered justified to read across to this study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
