Description of key information

Short term toxicity test was predicted using SSS QSAR in static condition using fresh water for 48 hrs.From that the EC 50 value for Daphnia magna for Undecenal was predicted to be 7.593779087 mg/l.
According to the CLP regulation the chemical was classified in chronic category 2 but as the chemical was readily biodegradable so the chemical was considered as not classified as per the CLP regulation.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
7.594 mg/L

Additional information

Various predicted data for the target chemical Undecenal were reviewed to summarize the following information: 

48 hrs aquatic toxicity study (SSS QSAR prediction model, 2016) was conducted to assess toxic effects of the test compound Undecenal (CAS no: 1337-83-3) and the results were predicted. The study was based on the effects of the test compound on Daphnia magna in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test compound Undecenal was estimated to be7.593779087 mg/l on the basis of mobility. 

  

48 hrs aquatic toxicity study (Danish QSAR prediction model, 2016) were conducted to assess toxic effects of the test compound Undecenal (CAS no 1337-83-3) and the results were predicted. The study was based on the effects of the test compound on the Daphnia magna in a static fresh water system. The predicted data suggests the effective concentration (EC50) for the test Undecenal was estimated to be3.146678mg/l on the basis of mortality. 

On the basis of results of various predictions for toxicity to aquatic invertebrates, it can be considered that the chemical was classified in chronic category 2 but as the chemical was readily biodegradable hence, the chemical was considered as not classified as per the CLP regulation.
