Description of key information

Additional information

Test data are only available for short-term toxicity to terrestrial plants. A NOEC of ≥100 mg/kg d.w. has been determined for the effects of the test substance on emergence of Triticum aestivum, Lepidium sativum and Brassica alba seedlings. 17-day EC50 values for effects on growth of the three species were 29, 94 and >100 mg/kg d.w. respectively.

Further testing for toxicity to terrestrial organisms is not considered necessary because:

- The substance hydrolyses rapidly and its hydrolysis product has a Log Kow < 3, therefore, partitioning to the terrestrial compartment is expected to be minimal.

- PNECsoil has been calculated from PNECfreshwater on the basis of the equilibrium partitioning method; the risk characterisation ratio (RCR) based on PNECsoil is <1.
