Description of key information

The OECD 216 toxicity to soil microrganisms (Nitrogen transformation test) determined a NOEC of 1000 mg ai /kg soil dw with a structural analogue substance.

Key value for chemical safety assessment

Long-term EC10 or NOEC for soil microorganisms:
1 000 mg/kg soil dw
