Description of key information

The NOEC based on nominal test concentrations is 3.2 mg/kg dw. Taking also the potential loss of test substance into account a NOEC of 0.6 mg/kg dw was derived.

Key value for chemical safety assessment

Long-term EC10, LC10 or NOEC for terrestrial plants:
0.6 mg/kg soil dw

Additional information

The seedling emergence/growth test with three plant species resulted in a 21 day NOEC of 3.2 mg/kg dw (nominal concentration). Taking also the potential loss of the substance during the experiment into account a time average NOEC of 0.6 mg/kg dw (assuming a first order rate degradation during 21 day experiment) is estimated based on the neutral soil DT50 value of 66 hours.
