Description of key information

Soil microorganisms: Nitrogen transformation test. 

Key value for chemical safety assessment

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

Additional information

A study to assess the long-term effects of the test material after a single exposure on nitrogen transformation activity of soil microorganisms was performed in accordance with OECD No 2.16

The study was performed on one soil with a limit test concentration of 1000 mg bromide/kg soil with a 28 day incubation period.

The test material showed no significant effect on the nitrogen transformation activity of soil microorganisms at a test concentration of 1000 mg bromide / kg over a 28-day period.

The test material can be considered to have no long-term effect on nitrogen transformation in soil.
