On the grounds of the
physico-chemical properties of CTFE and the results on environmental
fate obtained from EQC Fugacity III Model (EQC
Fugacity III Model, v.2.02, May 2003)
Moreover, the Guidance
on Information Requirements and Chemical Safety Assessment Chapter R.7a:
Endpoint Specific Guidance, Appendix R.7.1-4 indicates that substances
with a Henry's Law constant of around 1 hPa m3/mole rapidly volatilize
The substance profile
itself indicates the difficulty to properly test CTFE and provide
meaningful results of its biodegradation in aqueous systems as well as
in sediment and soil. Nevertheless
a further assessment based on
Quantitative Structure Activity Relationships (QSARs) has been however
order to evaluate the biodegradation hazard profile of CTFE, the BIOWIN
v.4.10, EPI Suite v.4.0 model has been applied.
The prediction of the
BIOWIN model suggests that CTFE is not ready biodegradable.
