Description of key information

Data from a study conducted according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test) are available.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for terrestrial plants:
84.6 mg/kg soil dw

Additional information

Toxicity to terrestrial plants

The obtained results were considered to be valid for the AAPBs.

Short-term toxicity

In a study (limit test) conducted according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test), Triticum aestivum, Brassica alba and Lepidium sativum were exposed to a nominal concentration of 100 mg Coco AAPB/kg soil. A 17 d-NOEC ≥100 mg dry residue/kg soil d.w. nominal (= 84.6 mg a.i./kg) was determined for all three plant species in respect to emergence and growth. Analytical monitoring was not performed.

Long-term toxicity

As recommended in R.7.11.3.1 data obtained from the OECD 208 Guideline study have been used as estimates of chronic toxicity as they cover a sensitive stage in the life-cycle of a plant. The determined NOEC of 84.6 mg/kg (a.i. nominal) was used for PNEC derivation. In addition according to REACH Regulation (Annex X, 9.4, column 2), a study on long-term toxicity on terrestrial organisms does not need to be conducted if no direct or indirect exposure of soil is to be expected. Based on the uses of the test substance, soil is not the target compartment and therefore exposure of soil is expected to be low and furthermore the test substance proved to be readily biodegradable. Therefore additional testing is considered not necessary.
