90 percent of the TFA we consume comes from food sold in ordinary grocery stores, according to the Swedish National Food Agency's survey. New studies also show the substance's negative health effects.
The acceptable daily intake for humans is therefore being lowered from 0.05 mg/kg to 0.014 mg/kg.
TFA is the most common PFAS substance in the environment, according to the Geological Survey of Sweden. Several pesticides break down into the substance, as do most refrigerants used in air conditioning.
