JUSTIFICATION FOR DATA WAIVING
According to Annex IX REACH regulation, section 9.4, the equilibrium partitioning method was used to assess the hazard to soil organisms. The use in terrestrial applications is performed with 13 % solution of substance in water. The solution of desired concentration is prepared by mixing 180 g with 1 litre of water. For 1 hectare of soil, 0,6 litres of 13 % solution is used. Calculated PEC(soil) = 0,0072 mg/kg with density of soil 2500 kg/m3 according to ECHA Guidance on information requirements and chemical safety assessment. Calculated PNEC(soil) = 0,009052 mg/kg. Therefore, the risk characterisation ratio (RCR) of PEC(soil) to PNEC(soil) is below 1. The risks associated with terrestrial applications are well controlled.
