Description of key information

Based on read across, the 96 hour LL50 is >1000 mg/l WAF.

Key value for chemical safety assessment

Additional information

Wetton (1998) tested the toxicity of alkenes, C20 - 24 to Oncorhynchus mykiss in an OECD 203 test. Due to the low solubility of the test substance test organisms were exposed to water accommodated fractions (WAF) and exposure concentrations were expressed as a loading rate. The test was conducted as a limit test with a single exposure concentration of 1000 mg/l WAF. No mortality was observed at this loading rate, so the 96 hour LL50 >1000 mg/l WAF.
