100 mg/kg soil dw

Additional information

Studies of the effects on terrestrial organisms need not be conducted if direct and indirect exposure of the soil compartment is unlikely. It is proposed that testing is waived as, although the substance has a high Kow of 8.30 and a high potential to adsorb to soil, it is readily biodegradable indicating that it will not remain in the environment.

Data are available on two structural analogues, phthalate esters with linear alcohol chain lengths of C6 -8 and C6 -10. These have been tested for their effects of seedling emergence and seedling growth on three non-target plant species representing three plant families according to OECD test guidelines. All tested species showed no phytotoxic effects at the tested concentration compared to the control. The LC50 for seedling emergence and the EC50 for growth of Triticum aestivum, Lepidium sativum and Brassica alba were therefore observed to be greater than 100 mg/kg dry soil.
