Description of key information
Additional information
Only one valid data is available for the aquatic compartment (LC50(96h)=4.68 µg/L for O.mykiss). All the available data, even if quoted reliability 4, confirm this result and suggest that Phosphine is very toxic to aquatic organism, with toxicity threshold stricly below 1 mg/L.
As indicated by the current harmonised classification and labelling, phosphine is N R50, very toxic to aquatic organisms (29th ATP published as Directive 2004/73/EC). Indeed, considering that Phosphine is not stable in water the R53 phrase is not relevant for the substance.
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.
