If released to the atmosphere, vapour phase MMT(2-EHTG) will be degraded
by photochemically induced hydroxyl radicals, with a half-life of ca.
9.4 hrs. A Henry’s Law constant of 4.598E-06 atm m3/mol predicts that
MMT(2-EHTG) will volatilise only minimally from surface water;
half-lives from a model river or lake are 350 hours and 168.6 days,
respectively. Based on Level III distribution modelling it is estimated
that the majority of MMT(2-EHTG) released to the environment will
partition into soil (65.7 %) and sediment (17.4 %), with a somewhat
smaller amount in water (16.5 %).
The MMT (2 -EHTG) has shown to be readily biodegradable. It is expected
to rapidly degrade once introduced into the environment.
Modeling results show that MMT(2 -EHTG) has a low potential for
