Description of key information
It is considered that Uronium hydrogen sulphate and its degradation products (urea and sulfate salts) are not toxic to birds through long term exposure.
Key value for chemical safety assessment
Additional information
According to Section 9.6.1 of REACH Regulation 1907/2006, a long-term or reproductive toxicity study in birds is required. However, such a study is not justified for uronium hydrogen for the following reason:
Given the extensive use of urea products and sulfates as fertilisers and chemical treatments of soils, it is considered that urea sulfate and its degradation products (urea and sulfate salts) are not toxic to birds through long term exposure.
Testing of toxicity to birds is scientifically unjustified.
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.
