Description of key information

The purpose of this study was to investigate the long-term effects of the test item, after a single exposure, on nitrogen transformation activity of soil microorganisms, following the procedure described in the corresponding OECD 216 guideline and under GLP. The test item showed no significant adverse effect on the nitrogen activity of soil microorganisms up to the highest tested concentration over a 28-day period. The NOEC is therefore considered to be equal to or greater than 1000.0 mg test item/kg soil dry weight.

Key value for chemical safety assessment

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