Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
In accordance with section 2 of REACH Annex XI, the study does not need to be conducted as it is technically not feasible to conduct aquatic toxicology studies because phosgene hydrolyse rapidly (half - life = 0.026 seconds). Any effects resulting from the unlikely introduction of phosgene to surface waters will be attributed to the formation of hydrogen chloride (HCl) and an associated drop in pH. The acute ecological effects of HCl on fish, invertebrates and aquatic plants have been extensively studied. Therefore, the key value is based on information related to HCl.

Additional information
Any effects from the unlikely introduction of phosgene to surface waters will be attributed to the formation of hydrogen chloride and associated drop in pH. The acute ecological effects of HCl on fish, invertebrates and aquatic plants have been extensively studied. Acute LC50 values for hydrogen chloride to fish varied from 4.92 to 282 mg/l.
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.
