Description of key information

The results 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. 

Key value for chemical safety assessment

Additional information

Two publications are used as weight of evidence approach.

The results 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, macro-invertebrates, Callitriche sp., Lemna sp., and Impatiens capensis) was very low (low ppb range for microbial communities and low ppm range for oligochaetes and jewelweed).
