Description of key information
Additional information
Abiotic degradation:
Based on estimation with the QSAR model AOPWIN (v1.93), the substance using its SMILES notation FC(F)(F)C=CCl undergoes in air rapid degradation after reaction with hydroxyl radicals (ozone could not be estimated). The DT50 values after reaction with hydroxyl radicals are 1.782 days for the cis-isomer and 1.571 days for the trans-isomer (based on 24-hour time frame and 0.5E+06 OH radicals/cm3, default settings in AOPWIN). The DT50 values after reaction with ozone are 91.6 days for the cis-isomer and 45.8 days for the trans-isomer (at 7E+11 mol/cm3). The half-lives in the air are not used in the risk characterisation because it is not an experimental value. The rapid phototransformation in the air is supported by a publication (Andersen et al. 2008), which shows the atmospheric lifetime of the substance by reaction with OH radicals is approximately 26 days.
Based on a complete lack of hydrolysable groups, the substance may be expected to be hydrolytically stable. An estimated half-life at 20 °C of >1 year may be used for assessment.
Biotic degradation:
The biodegradability of the substance was determined in a screening study in accordance with OECD TG 301D. After the 28 day exposure period, the cumulative percentages biodegradation did not exceed 1% indicating that the substance is not readily biodegradable. Studies on biodegradation in water, sediment and soil were not performed. Based on the characteristics of the substance (gaseous at room temperature with a vapour pressure of 1065 hPa and a Henry's law constant of 4.64E+03 Pa*m3/mol) the stability of the substance in water, sediment and soil is to be considered as not relevant.
Bioaccumulation:
No bioaccumulation is expected in fish based on the log Kow of 2.2. Based on the physical state of the substance at room temperature (gaseous), the substance is not expected to be surface active or ionisable at environmental pH (pH 4-9). The BCF in aquatic organisms was estimated using the Veith relationship: log BCF = 0.85·log Kow - 0.70 (applicable for substances with log Kow ≤6). This results in an estimated BCF for fish of 14.8 L/kg w.w.
Transport and distribution:
The substance can be expected to have a low potential for adsorption based on the log Kow of 2.2. The substance at room temperature is gaseous. The substance is not expected to be surface active or ionisable at environmental pH (pH 4-9). The organic carbon-water partitioning coefficient (Koc) was calculated from the log Kow using the non-hydrophobics QSAR in EUSES: log Koc = 0.52·logKow + 1.02). The calculated Koc value is 146 L/kg (log Koc = 2.16). This predicted value is used in the assessment.
The Henry's law constant is calculated in EUSES using the substance's molecular weight of 130.5 g/mol, the experimentally determined vapour pressure of 1065 hPa (at 19.93 °C) and the water solubility of 1900 mg/L (at 20 °C). The Henry's law constant at environmental temperature (12 °C) is calculated to be 4.64E+03 Pa·m³/mol. Based on this value, the substance is expected to volatilise rapidly from water.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
