Additional information

There are no data describing the long-term toxicity of the registered substance to terrestrial plants. However, data are available with D6 for toxicity to macroorganisms except arthropods and soil microorganisms.

A long-term (56 day) NOEC value of≥1000 mg/kg dry weight 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 has been determined for the effects of the test substance on nitrate formation rate (no effects at the highest concentration tested).

In addition, acute and chronic aquatic toxicity data are available with D6 or are read across from structural analogues. The data show no acute or chronic effects at the limit of solubility of the substance. Since the aquatic and terrestrial data available for D6 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.
