Ethylene glycol is a colorless, odorless, sweet-tasting but poisonous type of alcohol found in many household products. The major use of ethylene glycol is as an antifreeze in, for example, automobiles, in air conditioning systems, in de-icing fluid for windshields, and else. People sometimes drink ethylene glycol mistakenly or on purpose as a substitute for alcohol. Ethylene glycol is toxic, and its drinking should be considered a medical emergency. The major danger from ethylene glycol is following ingestion. Due to its sweet taste, peoples and occasionally animals will sometimes consume large quantities of it if given access to antifreeze. While ethylene glycol itself has a relatively low degree of toxicity, its metabolites are responsible for extensive cellular damage to various tissues, especially the kidneys. This injury is caused by the metabolites, glycolic and oxalic acid and their respective salts, through crystal formation and possibly other mechanisms. Toxic metabolites of ethylene glycol can damage the brain, liver, kidneys, and lungs. The poisoning causes disturbances in the metabolism pathways, including metabolic acidosis. The disturbances may be severe enough to cause profound shock, organ failure, and death. Ethylene glycol is a common poisoning requiring antidotal treatment.

Lymphocytes from former uranium miners who finished work underground one or more decades ago were analysed with respect to possibly persisting genetic damage induced by their radiation exposure. A modified micronucleus-centromere test was used which determined the frequency of micronucleus-containing binucleate cells after cytochalasin B treatment and the percentage of centromere-free micronuclei, assessed with the help of immunofluorescence labeling of centromere protein B. Whereas the overall frequency of micronucleus-containing cells was not significantly elevated above the level found in a control group, former miners showed a greater percentage of centromere-free micronuclei, i.e. micronuclei containing only acentric fragments. Our results are in excellent agreement with those of an earlier uranium miner study and lend support to the assumption that genetic damage from alpha radiation can persist for many years after exposure, possibly due to genomic instability. The frequency of micronucleus-containing cells, but not the percentage of centromere-free micronuclei, significantly increased with time since last exposure in the mines. This can be attributed, at least in part, to the fact that miners who have finished working underground longer ago tend to be older, and there is an increase of the frequency of micronucleus-containing cells with age.

Abstract:The article summarizes contemporary scientific knowledge of depleted uranium effects on human health due to its use in military conflicts. The discussion covers cases of minimal risk due to external irradiation resulting from the storage and handling of depleted uranium ammunition and, in contrast, important toxicological and radio-toxicological risks of late effects resulting from the inhalation and ingestion of dust particles produced by the burning of the core of the anti-tank ammunition.
