Is contaminated unrecorded alcohol a health problem in the European Union? A review of existing and methodological outline for future studies.

Aims: Some European countries with high levels of unrecorded alcohol consumption have anomalously high rates of death attributable to liver cirrhosis. Hepatotoxic compounds in illegally produced spirits may be partly responsible. Based on a review of the evidence on the chemical composition and potential harm from unrecorded alcohol, the Alcohol Measures for Public Health Research Alliance (AMPHORA) project's methodology for identifying, analysing and toxicologically evaluating such alcohols is provided.

Salivary acetaldehyde increase due to alcohol-containing mouthwash use: a risk factor for oral cancer.

Increasing evidence suggests that acetaldehyde, the first and genotoxic metabolite of ethanol, mediates the carcinogenicity of alcoholic beverages. Ethanol is also contained in a number of ready-to-use mouthwashes typically between 5 and 27% vol. An increased risk of oral cancer has been discussed for users of such mouthwashes; however, epidemiological evidence had remained inconclusive.

The role of acetaldehyde outside ethanol metabolism in the carcinogenicity of alcoholic beverages: evidence from a large chemical survey.

Acetaldehyde is a volatile compound naturally found in alcoholic beverages, and it is regarded as possibly being carcinogenic to humans (IARC Group 2B). Acetaldehyde formed during ethanol metabolism is generally considered as a source of carcinogenicity in alcoholic beverages. However, no systematic data is available about its occurrence in alcoholic beverages and the carcinogenic potential of human exposure to this directly ingested form of acetaldehyde outside ethanol metabolism.

Chemical composition of vintage preban absinthe with special reference to thujone, fenchone, pinocamphone, methanol, copper, and antimony concentrations.

Thirteen samples of authentic absinthe dating from the preban era (i.e., prior to 1915) were analyzed for parameters that were hypothesized as contributing to the toxicity of the spirit, including naturally occurring herbal essences (thujone, pinocamphone, fenchone), methanol, higher alcohols, copper, and antimony.

Determination of volatile constituents in spirits using headspace trap technology.

The use of headspace adsorbent traps in combination with gas chromatography was evaluated for the determination of volatile constituents (i.e. higher alcohols and other congeners of alcoholic fermentation) in spirits.

Quantification of selected volatile constituents and anions in Mexican Agave spirits (Tequila, Mezcal, Sotol, Bacanora).

A large collection (n = 95) of Mexican Agave spirits with protected appellations of origin (Tequila, Mezcal, Sotol, and Bacanora) was analyzed using ion and gas chromatography. Because of their production from oxalate-containing plant material, all Agave spirits contained significant concentrations of oxalate (0.1-9.
