Ethylene Glycol and Metabolite Concentrations in Fatal Ethylene Glycol Poisonings [PDF]
Journal of Analytical Toxicology, 2015 Ethylene glycol (EG) is used in antifreeze and other industrial products. It metabolizes to glycolic acid (GA) and oxalic acid (OX) that cause metabolic acidosis and are mainly responsible for the toxicity of EG. During 2010-2014, EG or GA was found in 25 postmortem cases in Finland.
