There are no data describing the long-term toxicity of the registered substance to terrestrial plants. However, data are available with L4 for toxicity to macroorganisms except arthropods and soil microorganisms.
A long-term (56 day) EC10 value of >1000 mg/kg dry weight, based on nominal, and equivalent to >400 mg/kg based on arithmetic mean concentration, has been determined for the effects of the test substance on reproduction of Eisenia fetida (no effects at the highest concentration tested).
A 28 day EC10 value of >100 mg/kg dry weight, nominal, has been determined for the effects of the test substance on nitrate formation rate.
In addition, acute and chronic aquatic toxicity data are available with L4. The data show no acute or chronic effects close to or above the limit of solubility of the substance. Since the aquatic and terrestrial data available for L4 all show no effects at the highest concentrations tested, in accordance with ECHA guidance, these tests are adequate for terrestrial risk characterisation and no further terrestrial toxicity tests are required. Therefore, the requirement for an OECD TG 208 study with the registration substance is waived, and no further testing is required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority.
