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.
