Materials and methods

Principles of method if other than guideline:
No specific studies concerning transport between environmental compartments were available or performed on Glyoxylic acid 50 %.
However, literature data showed that there is a possible presence of Glyoxylic acid in water, soils, plant tissues (see chapters 3.3.2, 3.7, 3.8, 4.8, 4.9). No study performed.

Results and discussion

Applicant's summary and conclusion

Conclusions:
No specific studies concerning transport between environmental compartments were available or performed on Glyoxylic acid 50 %.
However, literature data showed that there is a possible presence of Glyoxylic acid in water, soils, plant tissue. 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°).

If released into water glyoxylic acid is not expected to absorb to suspended solids and sediment based upon its estimated Koc.
If released to soil or water glyoxylic acid is expected to biodegrade.
If released to air, an estimated vapor pressure of 1 mm Hg at 25°C indicates glyoxylic acid will exist solely as vapor in the ambient atmosphere. Vapor-phase glyoxylic acid will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals.
