  • TFM is over 50 times more toxic in water at pH 6.5 than at pH 9.5
  • TFM is expected to remain in solution in the lake system and persist for long periods of time… TFM is chemically and biologically very stable. An examination of its structure, i.e., aromatic, fluoro-containing, m-substituted phenol, shows that the compound possesses many of the chemical features known to impart persistence to organic compounds.
  • When TFM is used, amphibians have regularly been found dead in creeks immediately after treatment in Lake Erie watersheds and elsewhere in the Great Lakes.
EPA Registered: Yes
  • Registered use in: Canada, US

Food Tolerances: Approximately 400,000 pounds of TFM were put into streams, creeks, and lakes in the Great Lakes Basin between 1993-1997. Many of these areas are prime fishing areas. Yet, there are no tolerances for TFM in the US because EPA considers the use of this compound to be non-food.
