Terrestrial toxicity

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.
