Nonitalics compounds are stabilizers. Italics compounds are chlorinated solvents; these are listed for comparison to show
whether the stabilizer is likely to evaporate with the solvent or remain behind in the soil where it can be leached down to
groundwater. Data for 1,4-dioxane are shown in boldface.

“MITI Probability,” also called “Inherent Biodegradability,” is determined by the Modii ed MITI Test, an activated sludge
assay of biochemical oxygen demand, from the Chemicals Inspection, and Testing Institute, Japan (OECD, 1981). MITI
probability values are included in BIOWIN output.
