Additional information

In accordance with column 2 of REACH Annex IX in the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. As the substance does not indicate high adsorption (log Koc <3) and is not persistent nor very persistent; and there is no indication that the substance is very toxic (EC/LC50 <1 mg/L for algae, daphnia or fish), the substance belongs according to REACH Guidance R.7C Table R.7.11-2 to soil hazard category 1. However, although the exposure assessment (see Chapter 9) based on PNECsoil(screen) does not indicate the risk for terrestrial compartment, the RCR to soil compartment is close to 1, further testing is proposed for terrestrial toxicity: the toxicity of the test item to earthworms was already studied according to OECD 207 guideline (no mortality was observed even at the highest concentration tested of1000 mg/kg dry weight substrate), toxicity to terrestrial plants and soil microorganisms are thus proposed.
