12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated in fish for methyl methanesulfonate(SRC), using an estimated log Kow of -0.7(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl methanesulfonate can be estimated to be 12(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl methanesulfonate is expected to have very high mobility in soil.
