ABSTRACT By using 1,4-dioxane as the sole source of carbon, a 1,4-dioxane-degrading microorganism was isolated from soil. The fungus, termed strain A, was able to utilize 1,4-dioxane and many kinds of cyclic ethers as the sole source of carbon and was identified as Cordyceps sinensis from its 18S rRNA gene sequence. Ethylene glycol was identified as a degradation product of 1,4-dioxane by the use of deuterated 1,4-dioxane-d 8 and gas chromatography-mass spectrometry analysis. A degradation pathway involving ethylene glycol, glycolic acid, and oxalic acid was proposed, followed by incorporation of the glycolic acid and/or oxalic acid via glyoxylic acid into the tricarboxylic acid cycle.

Ethylene glycol poisoning is not uncommon in India. The ill effects are primarily caused by its toxic metabolites: glycolic acid and oxalic acid. A 70-year-old female presented to our hospital with ataxia after ingestion of ethylene glycol. The reported case describes the management of ethylene glycol poisoning using oral ethyl alcohol as an alternative to the recommended intravenous ethyl alcohol and fomepizole that are not available for use in India. The need for high degree of clinical suspicion, targeted investigations, and early instigation of treatment is of prime importance in cases of ethylene glycol poisoning as it can lead to long-term complications or even death.

Organic substances of simple composition, like marsh-gas, ethylene, alcohol, and acetic acid, are deserving of most careful study, not merely on account of their being repre­sentative members of numerous and important classes of bodies, but also because they form connecting links between the compounds of inorganic chemistry and the more complicated forms of organic nature. Glyoxylic acid belongs to this class of bodies, because it bears the same relation to oxalic acid that sulphurous acid does to sulphuric acid, and because it stands to glycolic acid as common aldehyde, C 2 H 4 O, does to alcohol, C 2 H 6 O. These relations suggested the experiments which will be described in the following pages.

The ozonation of maleic acid in aqueous solution (pH 3) leads to the formation of glyoxylic acid and formic acid which are oxidized to the stable endproducts oxalic acid and CO2 in the further course of the reaction.With fumaric acid besides the double bond cleavage (75%) an anomalous ozonolysis is observed leading to the formation of the unstable intermediate mesoxalic acid semialdehyde which is oxidized to mesoxalic acid.In both cases 45% of the organic carbon appear as CO2 after the complete elimination of the initial compounds. The specific ozone consumption in our experiments was 4 mmol O3 per mmol of acid.On account of the quantitative follow up of the oxidation products the reaction mechanisms are discussed. The oxidation of glyoxylic acid, formic acid, oxalic acid and mesoxalic acid as pure substances by ozone gives qualitatively the same results as in the mixtures.

Glyoxylic acid contains one atom of oxygen less than oxalic acid, and may be considered as glycolic acid minus two atoms of hydrogen. It therefore bears to these two acids the same relation that oil of bitter almonds does to benzoic acid and benzylic alcohol. On another occasion it has been shown to possess other properties in common with hydride of benzoyl.

Abstract In this study, the removal of salicylic acid (SA) in water by ozone (O3) and ultraviolet/ozone (UV/O3) processes was investigated. Results showed that more than 50% of SA (10 mg/L) could be effectively removed after 1 min during these two processes. However, the UV/O3 process was much more effective than the O3 process for SA mineralization, and the total organic carbon reduction after 30 min was 69.5% and 28.1%, respectively. In the two processes, the optimum pH value for SA removal was 4.3, while that for SA mineralization was 10.0. Both bicarbonate and dissolved organic carbon significantly inhibited SA removal during the two processes. Eleven oxidation byproducts were detected in O3 process, but only four byproducts were observed in UV/O3 process. Three hydroxylation aromatic products were identified as the initial byproducts during SA degradation. Glyoxylic acid monohydrate, glycolic acid, and oxalic acid were accumulated in O3 process but not observed in UV/O3 process. Oxalic acid was the only detected small molecular byproduct in UV/O3 process, and it could be further mineralized, thereby indicating that UV/O3 had a greater potential for degrading both SA and its reaction byproducts.
