[Determination of toxic element concentrations in flour and cereal products by mass spectrometry with inductively coupled plasma].

Systemic control and monitoring in the sphere of providing sanitary epidemiological welfare of population require routine procedures for determining toxic elements in variable foodstuffs. Their development is a pressing issue. Our research was to develop a procedure for determining concentrations of arsenic, cadmium, lead, mercury, aluminum and strontium in flour and cereal products by mass spectrometry with inductively coupled plasma.

[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. .

[Phthalate analysis in foods for young children using LC-MS method].

Phthalates are esters of phthalic acid, which are persistent organic pollutants of the environment. Phthalates are widely used as plasticizing additives in the production of polymer products for industrial, domestic, food and medical purposes. The ubiquitous presence of phthalates is confirmed by the results of studies of environmental objects, drinking water, and foodstuffs.

[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.

[Determination of phthalates in juice product by high-performance liquid chromatography/mass spectrometry].

The paper presents the research results obtained after determination of the persistent organic pollutants of the environment - phthalates in domestic juice products with the use of high-performance liquid chromatography/ mass spectrometry (HPLC/MS/MS) with application of solid-phase extraction as a method of sample preparation. Selective determination of phthalates in fruit and vegetable juices by HPLC/MS/MS method has been provided through parent and child ions' monitoring that are formed during ionization of the molecules of the studied compounds in the electrostatic spray of isomers on a reversed-phase column. The analysis of the samples of juice product revealed the presence of 11 phthalates out of 13 studied in concentration range from 0.
