Remarks:
No study performed. Based on a classification scheme and an estimated Koc value of 1, indicates that glyoxylic acid is expected to have very high mobility in soil. By analogy to other aliphatic acids, biodegradation is expected to be an important degradation process for glyoxylic acid in soil. Volatilisation of glyoxylic acid from moist soil surface is not expected to be an important fate process since the anion will not volatilize. Glyoxylic acid may volatilize from dry soil surfaces based upon its vapor pressure of 1 mm Hg at 25°C.
