Description of key information

Additional information

The aquatic toxicity of butylal was assessed in a fish test. In this test the 96h LC50 was between 46 and 100 mg/L test substance. With a QSAR calculation this dimension could be verified (23.4 mg/l). For the toxicity of butylal to invertebrates and algae no measured data are available. QSAR calculations predict effect levels to invertebrates and algae which are in the same range as the toxicity to fish.
