Potential of endogenous formation of volatile nitrosamines from Nigerian vegetables and spices.

چکیده
Nitrosatability of dried Nigerian vegetables and spices was investigated under simulated gastric conditions. N-Nitroso-dimethylamine (NDMA) was the only volatile nitrosamine found above the preformed level except in ugwu where N-nitroso-piperidine (2.3 ppb) was also detected. The lowest NDMA value of 0.4 ppb was found in bitterleaf while onions had the highest level (14.7 ppb) of nitrosation. The results suggest that, under endogenous conditions, nitrosation of these foodstuffs could be an important contributory factor in cancer aetiology.

Volatile N-nitrosamines were detected in the urine of male volunteers with gas-liquid and high-pressure liquid chromatography interfaced to the thermal energy analyzer. Of 50 samples from normal males, 10 contained nitrosodimethylamine (0.02 to 0.10 micrograms/liter), 6 contained nitrosodiethylamine (0.02 to 3.10), 9 contained nitrosomorpholine (0.006 to 0.67), and none contained nitrosodibutyl...
متن کاملVolatile N-nitrosamine formation after intake of nitrate at the ADI level in combination with an amine-rich diet.
Formation of nitrite from ingested nitrate can result in several adverse health effects and implies a genotoxic risk as a consequence of endogenous formation of carcinogenic N-nitroso compounds. We studied the formation of volatile N-nitrosamines after intake of nitrate at the acceptable daily intake (ADI) level in combination with a fish meal rich in amines as nitrosatable precursors. Twenty-f...
متن کاملPublic Health Implications of Antibiotic-Resistant Bacteria Associated with Suya Spices in Nigeria
Background: The emergence and re-emergence of antibiotic-resistant foodborne bacteria call for concerted efforts, especially in developing countries. Spices have been employed traditionally to improve the aroma and flavour of foods; however, they could serve as reservoirs for the spread of potential pathogenic organisms. This study aims to investigate the public health implications of antibiot...

A hydrmetallurgical study based on the extraction of Zn and Pb from a Nigerian sphalerite mineral leached with 4 M hydrochloric acid has been undertaken. Triphenylphosphite (TPP) has proved to be very effective for the extraction of zinc. With 2 M TPP and at ambient temperature of 25±2°C; 35.71% and 66.7% of Pb and Zn were extracted, respectively, into the organic phase within 60 min. The recov...
