The Koc of glyoxal was measured to be 2.1 (log Koc = 0.32) (BASF, 1996). This indicates no significant potential for adsorption to soils or sediments.

Henry's Law Constant

The Henry's Law Constant of glyoxal at ambient temperature (15-25 °C) is = 3.38E-04 Pa*m³*mol-1 (Betterton & Hoffmann, 1988). This indicates that the compound will not evaporate into the atmosphere.


Following the Mackay Level I calculations, glyoxal will preferentially distribute into the water (ECT, 2008).
