Formaldehyde (HCHO) is the simplest and most common aldehyde. At normal ambient temperatures it is a colourless gas with a pungent odour. It boils at - 21 OC and melts at - 92OC. Formaldehyde occurs naturally and is an important industrial chemical. In the indoor environment it
This suggests that formaldehyde levels normally encountered in indoor air, not exceeding 0.2 mg/m 3, are not expected to increase internal organ exposure.
1 sty 2011 · In total, 132 samples (26%) contained formaldehyde with an average of 0.27 mg/L (range 0–14.4 mg/L). The highest incidence occurred in tequila (83%), Asian spirits (59%), grape marc (54%), and...
Mean concentrations of formaldehyde in a variety of alcoholic beverages ranged from 0.01 mg L -1 in white spirits to 0.69 mg L -1 in brandies. ...
Formaldehyde (HCHO) is of greatest importance, due to its prevalence in the indoor environment and its known health impacts (WHO, 2010). The presence of volatile organic compounds (VOCs) and...
5 lut 2024 · Alcoholic beverage samples (N = 236) were collected and analyzed for formaldehyde by liquid chromatography-tandem mass spectrometry. The highest average concentrations were detected in fruit wines (1.71 µg/g), followed by wines (1.15 µg/g), cheongju (0.95 µg/g), soju (0.85 µg/g), takju (0.64 µg/g) and beers (0.61 µg/g). We assessed the ...
Sources that influence indoor levels of formaldehyde can be divided into two broad categories: combustion and off-gassing. Combustion sources include cigarettes and other tobacco products, and open fireplaces.
