Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

toxicity to soil microorganisms
Data waiving:
other justification
Justification for data waiving:
the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
Justification for type of information:
In accordance with column 2 of REACH Annex IX, the toxicity to microorganisms study does not need to be performed as the substance is highly unlikely to have any contact (exposure to) soil, either directly or indirectly.

Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , study for effects on terrestrial organisms and plants  need not be conducted if: - These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.

Key value for chemical safety assessment

Additional information

No terrestrial  toxicity data are reported forO-isobutyl ethylthiocarbamate. Given the low potential for O-isobutyl ethylthiocarbamate reaching the terrestrial compartments (EQC modelling results), the lack of persistence (ready biodegradability under aerobic conditions) or bioaccumulation (BCFWIN modelling results), and the low likelihood of the  chemicalpartitioning to soil and sediments (EQC modelling results), the lack of ecotoxicity data is not considered a deficiency
