The registrant considers it justified to omit the bioaccumulation study
for this endpoint based on a lack of environmental exposure. However, in
order to allow the CHESAR software to function correctly an indicative
value of Log BCF = 3.031 has been used in the Chemical Safety
Assessment. Given the limitations of the predictive software the
registrant considers that this result must be regarded with some caution.
There are no experimental results on bioaccumulation of MMT[EHTG]
available. The Log BCF of MMT[EHTG] has been estimated by the BCFBAF
v3.01 sub-model resident within EPIWEB v4.1 as 3.031.
Similarly, employing the Base-line BCF model (Dimitrov et al., 2005) the
estimated log BCFmax and log BCFcorr values were determined for
MMT[EHTG] and equalled 1.61 and 0.97 respectively. The BCFcorr value
derived using the Base-line BCF model is indicative of a low potential
for bioaccumulation of the molecule.
Taken together, the BCFBAF and Base-line BCF models are indicative of a
low potential for bioaccumulation of MMT[EHTG].
Terrestrial exposures are not anticipated. MMT[EHTG] has a low potential
MMT[EHTG] does not accumulate in organisms.
Predictions made using the above-mentioned models rely on the Log Kow as
predicted by EPISUITE, which is considered to be higher than the
experimetally determined value and thus indicative of a worst case
