Toxicity to soil macroorganisms except arthropods
Administrative data
- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Type of information:
- experimental study planned
- Study period:
- To be confirmed.
- Justification for type of information:
- ECHA communication number TPE-D-2114551772-46-01/D provided for a draft decision requesting this study to be conducted. The registrant does not intend to challenge this request, and hence this test is included as a proposal for transparency. The testing will be undertaken in accordance with the requirements of the final decision and the dossier duly updated.

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 222 (Earthworm Reproduction Test (Eisenia fetida/Eisenia andrei))
- Version / remarks:
- The Earthworm Reproduction Test (test method: OECD TG 222), the Enchytraeid Reproduction Test (OECD TG 220) and the Collembolan Reproduction Test in Soil (OECD TG 232) are appropriate to cover the information requirement for long-term toxicity on terrestrial invertebrates (ECHA Guidance R.7.11.3.1). OECD 222 is selected as appropriate to address the requirements as an appropriate test.
