ABSTRACT

Diethylene glycol monobutyl ether may be released to the environment via a wide variety of effluents at sites where it is produced or used as a solvent or intermediate. Diethylene glycol monobutyl ether is not expected to undergo hydrolysis or direct photolysis in the environment. The complete miscibility of diethylene glycol monobutyl ether in water suggests that volatilization, adsorption and bioconcentration are not important fate processes. This is supported by the estimated Henry's Law constant, which indicates that volatilization of diethylene glycol monobutyl ether from natural waters and moist soil should be extremely slow. A low estimated log BCF suggests diethylene glycol monobutyl ether should not bioconcentrate among aquatic organisms. A low Koc indicates diethylene glycol monobutyl ether should not partition from the water column to organic matter contained in sediments and suspended solids, and it should be highly mobile in soil.
