Description of key information

The calculated 96 h LC50 values  for representative substances within this  Category showed a short term toxicity to fish range of  19-27.4mg/l

Key value for chemical safety assessment

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. 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.

Therefore, the use of a QSAR to predict the ecotoxicity of representative components of these streams is an appropriate technique to use as part of a weight of evidence approach. The use of ECOSAR is appropriate for this Category as these streams falls within the applicability domain of the model.
