Toxicity to soil macroorganisms except arthropods
Administrative data
- Endpoint:
- toxicity to soil macroorganisms except arthropods: long-term
- Remarks:
- No long-term data are considered to be needed , since substance is biodegradable and not adsorptive.
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment

- Eisenia fetida
- Animal group:
- annelids
- Details on test organisms:
- no data available
Study design
- Study type:

- Details on test conditions:
- Glass jars were used as test containers. 750 g of artificial soil which had been treated with one of the test chemicals (or a control with no chemicals) were placed in each jar. Ten E. fetida each with live weights of approximately 1 mg were added to each jar. There were four replicates of each chemical and dose.
