Description of key information

On the basis of read across, acute toxicity is not expected at the limit of solubilty.

Key value for chemical safety assessment

Additional information

Experimental data are not available for icos-1 -ene. In the absence of data for icos-1 -ene, data have been read across from category members with a lower carbon number.

Drottar and Swigert (1995) tested the toxicity of tetradec-1 -ene and Douglas and Halls (1993) tested the toxicity of hexadec-1 -ene to Oncorhynchus mykiss in an OECD 203 test. Due to the low solubility of the test substances test organisms were exposed as 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 1000mg/l WAF. No mortality was observed at this loading rate, so the 96 hour LL50 is >1000mg/l WAF.

These results indicate that we would not expect icos-1 -ene to exhibit acute toxicity to fish at exposure concentrations up to its limit of solubility.
