toxicity to soil microorganisms
Type of information:
experimental study planned (based on read-across)
Study period:
After approval by ECHA
Justification for type of information:
See IUCLID Sections 6.0 and 6.3 (CSR Sections 7.0 and 7.2) for discussion and justification of read-across.
according to
OECD Guideline 216 (Soil Microorganisms: Nitrogen Transformation Test)
Principles of method if other than guideline:
The registrants recommend that the stability of test substance concentrations in the soil under realistic test conditions must be explored as part of method development. Subsequent, toxicity testing is subject to satisfactory results from the stability studies.

Description of key information

Key value for chemical safety assessment

Additional information

An OECD TG 216 study is proposed with the read-across substance, silsesquioxanes, phenyl (CAS 70131-6-0). See IUCLID Sections 6.0 and 6.3 (CSR Sections 7.0 and 7.2) for further discussion.
