    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. The level at which an average consumer could detect acetaldehyde is still considerably lower than any toxicity.

    A product of alcohol metabolism that is more toxic than alcohol itself, acetaldehyde is created when the alcohol in the liver is broken down by an enzyme called alcohol dehydrogenase.

    At 50 ppm acetaldehyde, no irritation or local tissue damage in the nasal mucosa is observed. When taken up by the organism, acetaldehyde is metabolized rapidly in the liver to acetic acid. Only a small proportion is exhaled unchanged. After intravenous injection, the half-life in the blood is approximately 90 seconds.
