Description of key information

Additional information

This substance is not directly applied to soil and based on its intended use will not enter the terrestrial environment and therefore no testing of terrestiral organisms is required. The indirect exposure of soil to this substance via sewage sludge is also of no concern based on the material's high water solubility and predicted lack of adsorption. In accordance with section 9.4 of REACH Annex IX and X, further tests do not need to be conducted if direct and indirect exposure of the terrestrial compartment is unlikely. ECHA Chapter R.7B and R.7C guidance states that if the PEC/PNEC ratio is below 1, then no risk for the compartment is indicated, that the information available may be sufficient to conclude the assessment, and there is no need to perform further tests. In addition, ECHA Chapter R.7B guidance states that if the substance is not considered a PBT or vPvB candidate, then it is considered not necessary to conduct further testing on the compartment. Therefore, on the basis of a lack of potential exposure, and hence risk, and low risk demonstrated by the RCRs less than 1 based on EUSES modelling, it is considered that Acute Toxicity to Earthworms is inappropriate and indeed short term aquatic toxicity effects can be used as a worst case scenario for risk characterization of the terrestrial compartment should such characterization be required.
