14 cze 2024 · Chronic and prolonged exposure to large amounts of acetaldehyde can cause serious impairment of body function. This is because this toxin damages many key tissues and organs and is a carcinogen. The oesophagus, large intestine, pancreas and liver are particularly susceptible to carcinogenic effects.
21 gru 2021 · Acetaldehyde is an aliphatic aldehyde that exists at room temperature as a colorless gas with a fruity, pungent odor. It is miscible with water, ether, benzene, gasoline, solvent naphtha, toluene, xylene, turpentine, and acetone. It is very flammable and is unstable in air (Akron 2009, HSDB 2009).

Acetaldehyde is the main metabolite of ethanol and this reaction is catalysed by alcohol dehydrogenases (ADH). Five ADHs have been characterized in humans, two of which (ADH2 and ADH3), are known to be polymorphic.
Acute (short-term) exposure to acetaldehyde results in effects including irritation of the eyes, skin, and respiratory tract. Symptoms of chronic (long-term) intoxication of acetaldehyde resemble those of alcoholism.
Although the levels produced by this process are minute acetaldehyde has an exceedingly low taste/odor threshold of around 20–40 ppb and can cause an off-taste in bottled water. [69] The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity.
Page 18, lines 9-11: “Acetaldehyde is an intermediary in the normal catabolism of deoxyribose phosphate and various amino acids. A quantitatively much more important source of acetaldehyde in the body, however, is its formation through the action of alcohol dehydrogenase on ingested ethanol.”
