[Identification and chromatemass- spectrometry quantification of toxic chemicals (N-nitrosamines, phthalates) in baby foods].

Currently, assessing exposure to toxic chemicals detected in foodstuffs is a vital issue, especially regarding foods for babies and toddlers. The research was to identify and quantify toxic chemicals (N-nitrosamines, phthalates) in baby foods. .

[Comparative assessment of N-nitrosamines' contamination of baby's canned meat with vegetables and cereals by various methods in Russia and Vietnam].

The quality and safety of food, intended for baby in particular, is one of the global issues of our time. The group of carcinogenic N-nitrosamines is of especially dangerous. It is worth mentioning that currently there are no standards for their content in Vietnam.

[Development and application of gas chromatographymass spectrometry method for quantitive determination of volatile N-nitrosamines in smoked meat products].

The article presents the results of experimental studies on the development of highly sensitive and selective chromatography-mass spectrometry technique for the determination of 9 N-nitrosamines in food samples (sausage products) using distillation and an automatic solid-phase extraction system on Coconut cartridges for sample preparation. In the elaborated conditions of sample preparation (distillation and solid-phase extraction) and chromatography-mass spectrometric analysis, we achieved a high recovery and efficiency of the separation of nine N-nitrosamines. The quantitation limit was at level of 0.

Diagnostics of Early Changes in the Immune System Due to Low Concentration of N-Nitrosamines in the Blood.

The concentration of N-nitrosamines (N-nitrosodimethylamine and N-nitrosodiethylamine) was measured in blood samples from children after consumption of drinking water with high content of nitrates (main group) or water meeting health standards (reference group). N-nitrosodimethylamine level in the blood from children of the main group differed from that in the reference group by 2.6 times (0.

[Determination of N-nitrosodiphenylamine in meat canned food for children by the method of chromato-massspectrometry].

This study demonstrates the results obtained from the GC/MS experimental determination of low concentrations of N-nitrosodiphenylamine in meat canned baby food in the concentration range of 0.027-3.89 mg/kg.
