Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
The aquatic toxicity of sulphur trioxide is addressed/to be addressed by read-across from sulphuric acid. Read-across from sulphuric acid is justified based on the rapid reaction of sulphur trioxide with water to form sulphuric acid.
Adequate published studies are available to address the short-term and long-term toxicity of sulphuric acid to fish; studies are also summarised in the OECD SIDS (2001).
A short-term toxicity study has been conducted with Daphnia, an adequate published study is available to address the long-term toxicity of sulphuric acid to aquatic invertebrates.
An algal inhibition study has been conducted. Inadequate information is available to address the toxicity of sulphuric acid to microorganisms: a testing proposal is therefore included for this endpoint.
Additional information
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.
