Endpoint:
toxicity to soil microorganisms
Type of information:
experimental study planned
Justification for type of information:
The REACH Regulation provides some adaptation possibilities (Column 2 of Annex IX):
1) These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely: the direct or indirect exposure of the soil compartment cannot be excluded.
2) In the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment: some information and some data are not available because the substance is inorganic.
Because of previous considerations, an experimental study was planned.

The substance is not an agrochemical. According to ECHA Guideline R.7c, the OECD 216 method is would be reccommended because for most non-agrochemicals the nitrogen transformation test is considered sufficient as nitrate transformation takes place subsequent to the degradation of carbon-nitrogen bonds.
