12.2 Persistence and degradability

Four pure cultures of bacteria, isolated from either soil or activated sludge, were unable to utilize 1,2-dimethoxyethane as a carbon source(1).

12.3 Bioaccumulative potential

An estimated BCF value of 0.4 was calculated for 1,2-dimethoxyethane(SRC), using a measured log Kow of -0.21(1) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms will be low(SRC).
