Description of key information

EL50 (14 d) > 1000 mg/kg soil d.w. (germination in soil) (Lactuca)

Key value for chemical safety assessment

Additional information

A plant toxicity study is available for octane by Hulzebos et al. (1993). Lettuce (Lactuca sativa) seeds were exposed to soil treated with octane at concentrations of 1000 mg/kg (soil dry weight). Examination of germination on day 7 and 14 showed no effects. The authors also assessed germination in a nutrient solution containing octane. Here, octane did not show any effects up to the limit of solubility.

Further data are reported in Boyles (1976) on two other species, including the genera Daucus and Helianthus. However, the documentation on the samples and results is insufficient to rate this study for reliability.
