Description of key information
Additional information
Experimental results were identified for the three trophic levels: algae (Thiebaud 1999), Daphnia (Thiebaud 2000) and fish (Drottar 1999). These studies had variable reliability of Kilmisch scores 1 and 2. The following sections detail the robust summaries for these studies in the appropriate sections.
The results from these studies and the biodegradation data indicate that 2-methylpropane-2-thiol will be classified as chronic category 2, under GHS, with the hazard phrase "toxic to aquatic life with long lasting effects". 2 -methylpropane-2 -thiol would be classified as R51/53 under DSD, with the risk phrases "toxic to aquatic organisms" and "may cause long term adverse effects in the aquatic environment".
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.
