Description of key information

Studies investigating toxicity to terrestrial plants are scientifically unjustified and therefore not required for potassium formate on the basis that direct and indirect exposure of the soil compartment is unlikely.

Although data is not required for this endpoint, a reliable study is available which investigated the root length of Allium cepa exposed to potassium formate for 4 days, showing a nominal EC50 value of 50 mg/L (Joutti et al., 2003).

Key value for chemical safety assessment

Additional 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 potassium formate 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.
