Additional information

TFAH reacts violently with water and is instantaneously degraded in TFA which is the relevant substance for risk assessment and classification & labelling purposes.

No bioaccumulation studies obtained from established experimental protocols are available for TFA. The substance is expected to have a low potential for bioaccumulation.

However, the results of publications data indicate a low level of incorporation of TFA by natural microbial communities and thus their potential to serve as a point for TFA to enter into the food web. Overall incorporation of radioactive TFA in aquatic organisms spanning a range of trophic levels (microbial communities, oligochaetes, macroinvertebrates, Callitriche sp., Lemna sp., and Impatiens capensis) was very low (low ppb range for microbial communities and low ppm range for oligochaetes and jewelweed).
