Description of key information
Additional information
Adsortion/desorption tests results show that TFA is poorly absorbed to the soil and is considered as a mobile organic compound in the majority of soils investigated. The Kd ranged between 0.17 to 20 L/kg for organic and mineral soils (the organic horizon exhibiting greater retention) giving a geometric mean of 0.94 L/kg (SD=4.86, n= 20).
The Henry's Law constant (KH) for trifluoroacetic acid, 0.009 Pa.m3.mol-1, was calculated by the average of two measured values 8950 and 5800 mol.kg-1.atm-1 at 25°C reported in two valid peer reviewed studies.With such a value and because trifluoroacetic acid is totally miscible with water and has a log Kow value of 0.79 at 25°C, the preferred environmental compartment will be water, rather than air, ground or biota.Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
