VDF is not expected to be readily biodegradable.
biodegradation screening studies have been performed for VDF, however
data is available for related gaseous materials (e. g. pentafluoroethane
vinylidine chloride). Results with these substances showed ≤ 5%
degradation indicating that transformation to metabolites in soil and
water may be considered very low (SIDS, 2005 and NITE, 1992). Based on
these structural analogues, VDF is not expected to be readily
biodegradable (see Annex 4 for the Reporting Format). In addition,
calculated data is available from the BIOWIN™ model (U.S. EPA, 2000) the
results indicate that VDF will degrade in water and soil (timeframe of
days to weeks). Validation of this model showed thatthe
prediction “ready biodegradable” is frequently not in agreement with
experimental data obtained by the MITI I test. Therefore it is
recommended to use the results of the BIOWIN™
in a conservative way. If the program predicts fast biodegradation, this
estimate should not be taken into consideration. However, if the program
predicts slow biodegradation this can be used as a confirmation of not
readily biodegradable (Pavan and Worth, 2006). Therefore
the results of the BIOWIN™ model were assigned as not reliable.
