Description of key information

Experimental data are only available for 1 category member, tetradec-1-ene. The 14 day NOEC and LOEC for barley shoot growth was 10026ug/g and 25195ug/g. The 14 day NOEC for barley root growth was 31428µg/g.

Key value for chemical safety assessment

Additional information

Visser (2003) investigated the effects of tetradec-1 -ene on the root and shoot growth of barley following a non-standard method. Natural soil was exposed to tetradec-1 -ene in the field. Samples of soil were collected over time and used to test the toxicity of the test substance to barley in laboratory bioassays. The collected soil samples were analysed for physico chemical parameters and the concentration of the test substance. Barley was exposed to the soil samples and the effects on shoot and root length and weight recorded. No effects on root length were observed at any test concentration. A dose response effect was observed for shoot growth. The 14 day NOEC and LOEC for barley shoot growth was 10026ug/g and 25195ug/g. The authors also note that barley plants grown in the field on the exposed soil showed no effects on growth at 10026ug/g but were extremely inhibited at 25195ug/g dry weight.
