Remarks:

Scientifically accepted method, but EPI Suite not validated for organic salts This QSAR program does not not fully meet the OECD Principles for (Q)SAR Validation (inter alia no internal cross-validation and no external validation was performed); for some classes rather small training sets were used as experimental basis; results can nevertheless be used as rough estimation

Justification for type of information:

QSAR prediction: migrated from IUCLID 5.6

Description of key information

In accordance with column 2 of REACH Annex IX and X, the toxicity testing to terrestrial organisms shall be proposed depending on the results of the chemical safety assessment.

Direct exposure to soil is not likely, since the substance is not intentionally applied to soil. Indirect exposure to soil is not likely e.g. via agricultural use of sewage sludge since calcium diformate is readily biodegradable. Adsorption to solid soil phase is not expected (log Koc < 3). In conclusion no testing is required. As a consequence, no tests on terrestrial organisms are provided.
