Additional information

Based on the low logKow of trifluoromethanesulfonic acid, it is expected to have a low potential for adsorption onto soil and sediment (i.e. the substance has a logKow below 3).

For the calculation in the CSA, the equation of the TGD (Sabljic and Günsten, 1995) is applied to derive the logKoc value of the substance from its log Kow value. As no specific class is available for Trifluoromethanesulfonic acid in the proposed equations (e.g. no sulfonic acid class), the equation for "nonhydrophics" is selected as follows:

LogKoc = 0.52 * logKow + 1.02 = 0.52 * 0.3 + 1.02 = 1.176

[LogKoc: 1.176]
