N-nitrosodimethylamine in Spanish beers

Food and Chemical Toxicology, 1996
A survey of 21 beers produced in Spain during 1994 was conducted to assess contamination with volatile N-nitrosamines. N-Nitrosodimethylamine (NDMA), the only volatile N-nitrosamine detected, was found in 52% of Spanish beers at or above the detection level (0.05 microgram/kg).

Reduction of N-Nitrosodimethylamine with zero-valent zinc

Water Research, 2013
N-Nitrosodimethylamine (NDMA) is known as the disinfection by-product and the pollutant in the source water. Reduction with zero-valent zinc (Zn(0)) was investigated as a potential technology to treat NDMA. The results showed that Zn(0) was effective for NDMA reduction at initial pH 7.0.

N-Nitrosodimethylamine in beer

Food and Cosmetics Toxicology, 1980
Abstract Commercially-available bottled and canned beer was analysed for volatile nitrosamines using a chemiluminescence detector. N -Nitrosodimethylamine, the only volatile nitrosamine found, was detected in 23 of 25 samples analysed. The range of levels was 0–14 ppb (μg/kg) while the mean was 5·9 ppb.

N-nitrosodimethylamine in human blood

Food and Cosmetics Toxicology, 1980
Abstract Whole blood from 38 healthy persons (19 males and 19 females) was analysed for volatile nitrosamines. N-Nitrosodimethylamine was detected in blood samples from 97% of the individuals tested at a mean value (±1 SD) of 0·6 ± 0·4 ng/ml.

Atmospheric reactions of N-nitrosodimethylamine and dimethylnitramine

Environmental Science & Technology, 1984
The major atmospheric reactions of N-nitrosodimethylamine (NDMA) and dimethylnitramine (DMN) have been investigated in an approx.3500-L environmental chamber utilizing in situ long-path Fourier transform infrared spectroscopy. Rate constants for the reactions of OH radicals with NDMA and DMN were measured relative to that for dimethyl ether at 298 ...

Exposure to n-nitrosodimethylamine in a leather tannery

Food and Cosmetics Toxicology, 1979
Abstract N-Nitrosodimethylamine (NDMA) was detected in the atmosphere of a leather tannery at levels of up to 47 μg/m3. As far as we know this is the highest occupational exposure to this potent animal carcinogen yet discovered. NDMA was detected in all the air samples taken at different sites in the tannery on three visits in 1978. The highest level

Insight into the formation of N-nitrosodimethylamine in metformin products

Journal of Pharmaceutical and Biomedical Analysis, 2021
An effective analytical method for the quantification of N-nitrosodimethylamine (NDMA) using a liquid chromatography coupled with tandem mass spectrometry was developed and applied to a process optimization study of the production of metformin film coated tablets in order to identify the key factors behind the NDMA formation in metformin products.

N-Nitrosodimethylamine in dried dairy products

Food and Cosmetics Toxicology, 1980
Abstract Commercially available non-fat dried milk and dried buttermilk were analysed for volatile nitrosamines using a chemiluminescence detector. N-Nitrosodimethylamine, the only volatile nitrosamine that could be confirmed to be present by mass spectrometry, was detected in eight out of nine samples analysed.

N-nitrosodimethylamine in German beer

Food and Chemical Toxicology, 1989
A total of 514 beer samples (called 'first samples'), produced in Baden-Württemberg, FRG, between October and December 1987, were analysed for their N-nitrosodimethylamine (NDMA) content. In 302 of the samples NDMA was not detected (less than 0.2 microgram/kg), 191 contained indeterminable traces of NDMA (0.2-less than 0.5 microgram/kg) and 21 samples ...
