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 the substance, although having a high Kow of 9.74 and a high ability to adsorb to soil, it can be regarded as readily biodegradable indicating that it will not remain in the environment.

This is supported by data available on two structural analogues, phthalate esters with linear alcohol chain lengths of C6 -8 and C6 -10. The acute toxicity of these substances to the earthworm eisenia foetida was determined during a 14 day exposure period according to EEC Methods. No mortality occurred at the tested limit concentration of 1000 mg/kg dry soil and the 14 day LC50 was > 1000 mg/kg dry soil. These have also been tested for their effects on 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.
