Toxicity to terrestrial arthropods
Administrative data

Description of key information
In accordance with column 2 of REACH Annex IX and X, the toxicity testing on terrestrial arthropods does not need to be conducted as direct and indirect exposure of the soil compartment is unlikely. The reaction product and its constituent substances show a low bioaccumulative (low log Kow ) potential. Hence, a relevant distribution into soil and a considerable exposure of soil macroorganisms is not expected. There are however, 7 toxicity studies with terrestrial arthropods reported for the major constituent (LAS) of the substance to register (Marlon ARL).
Key value for chemical safety assessment
- Short-term EC50 or LC50 for soil dwelling arthropods:
- 82 mg/kg soil dw
- Long-term EC10, LC10 or NOEC for soil dwelling arthropods:
- 41 mg/kg soil dw
Additional information
The 21-day EC10 for springtails exposed to LAS in a range of soil types ranged from 82 - 205 mg/kg soil dry weight
The 21-day EC10 for mites exposed to LAS in soil was 100 mg/kg soil dry weight
The 10-week NOEC for mites exposed to LAS in soil was 320 mg/kg soil dry weight
The 8-week EC10 for springtails exposed to LAS in soil was 41 mg/kg soil dry weight
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
