Description of key information

The effects of the test item on the metabolic activity of soil micro-organisms were determined according to OECD Guideline 216 in year 2013. The NOEC for nitrogen transformation in soil measured as nitrate on day 7 was determined to be < 4.12 mg/kg soil dry weight. The NOEC for nitrogen transformation in soil measured as nitrate on day 14 as well as on day 28 was 37.0 mg/kg soil dry weight. It was not possible to calculate EC25 and EC50 values due to concurrent stimulation as well as inhibition effects.

Key value for chemical safety assessment

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