Tetrafluoroethylene (TFE) is a gas (B.P.
-76°C) of low water solubility. As consequence, exposure of the aquatic
environment, sediments and soil is unlikey. Further, an assessment of
the PBT status of Tetrafluoroethylene
(TFE) has been made using all
available data. This information suggets that that tetrafluoroethylene
does not meet the criteria for PBT/vPvB.
Tetrafluoroethylene is a gas (B.P. - 76°C) of low water solubility and
when released to the environment will enter almost exclusively the
ambient air. It has little tendency to paritition to biota or soil.
Because of its low sorption affinity, TFE is expected to be mobile in
soil. The most important degradation process occurs in the atmospheric
compartment. Consequently TFE will not be persistent in the aquatic
The estimated log Kow of TFE is 1.21, and
hence biocaccumulation is not expected. TFE is therefore considered not
The estimated acute effect concentrations are
much higher than the screening criterion of 0.1 mg/l. It can therefore
be expected that TFE is not toxic towards aquatic organisms. The chronic
effect concentrations for invertebrates, fish and algae are likely to be
much higher than the defined criterion of 0.01 mg/l. TFE is not
classified as mutagenic or toxic for reproduction, and because the
substance is a gas with short atmospheric lifetime chronic exposure of
mammals is unlikely. However, TFE is classified as carcinogenic in
experimental animals by a non-genotoxic mechanism (category 1B according
to Regulation 1272/2008 and category 2 according to Directive
67/548/EEC). Therefore, by the screening criteria TFE can be considered
The overall conclusions, of the PBT
assessment are that the criteria for PBT / vPvB are not met, and that
TFE can be considered to be not PBT/vPvB.
