Toxicity to soil macroorganisms except arthropods.001
Administrative data
- Purpose flag:
- key study
- Study result type:
- read-across from supporting substance (structural analogue or surrogate)
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- Not all information necessary is given, no results per
concentration given, no analytical monitoring and no GLP.
Despite these shortcomings, the results can be used.
