31 Ιουλ 2019 · Aldehydes, which are present within the air as well as food and beverage sources, are highly reactive molecules that can be cytotoxic, mutagenic, and carcinogenic. To prevent harm from reactive aldehyde exposure, the enzyme aldehyde dehydrogenase 2 (ALDH2)...
17 Αυγ 2022 · Based on the growing importance of exhaled aldehydes in breath research, this article provides a narrative review of the potential use of exhaled aldehydes as biomarkers for lung diseases.
Chronic exposure of humans to high levels of acrolein is considered unlikely because of its extreme irritation. At levels below those that cause olfactory or respiratory damage (~1 ppm), prolonged exposure to acrolein is intolerable, causing individuals to leave the contaminated environment.
Other than that, it contains inorganics VOCs viz. nitric oxide (10–50 ppb), 10 nitrous oxide (1–20 ppb), 10 ammonia (0.5–2 ppm), 11 carbon monoxide (0–6 ppm), 9 hydrogen sulphide (0–1.3 ppm) 12 etc. and organic VOCs such as acetone (0.3–1 ppm), 13 ethanol, isoprene (∼105 ppb), 14 ethane (0–10 ppb), methane (2–10 ppm), pentane ...
Abstract. Aldehydes are carbonyl compounds found ubiquitously in the environment, derived from both natural and anthropogenic sources. As the aldehydes are reactive species, therefore, they are generally toxic to the body.
23 Νοε 2019 · Aldehydes and volatile organic compounds (VOCs) are chemicals categorized with boiling points from 50–100 °C to 240–260 °C; therefore, they can be found indoors in the gaseous phase. Formaldehyde is a dominant aldehyde found indoors.
