Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Members of this category are gases at standard temperature and pressure, therefore conducting an aquatic ecotoxicity test is technically difficult and based on exposure estimates the test may not be relevant. Therefore, the use of a QSAR to predict the ecotoxicity of representative components of these streams is an appropriate technique for aquatic toxicity. In addition, it is difficult to assess the toxicity of UVCB streams using standard test methods. Instead, it is more appropriate to consider the toxicity of representative components of these streams.
The use of ECOSAR is appropriate for this Category as these streams falls within the applicability domain of the model. The calculated 96 hour LC50 values for representative substances within this Category showed a short term toxicity to fish range of 19 - 27.9 mg/L These values have been used in the PBT assessment of this category.
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.
