Description of key information

The adsorption/desorption test does not need to be conducted as based on the physico-chemical properties, the substance can be expected to have a low potential for adsorption (log Kow is 2.1). Therefore, the organic carbon-water partitioning coefficient (Koc) was calculated from the log Kow using the equation from EUSES (non-hydrophobics QSAR, because the log Kow < 3). The calculated Koc value is 129 L/kg (log Koc = 2.1). This predicted value is used in the assessment. Further studies on transport and distribution of Lyral in the environment are not available.
