Control by the accuracy of the results of studies for the lead content in samples applying the microwave laboratory system PLP-01M

Abstract

The article presents the analysis of the study results of samples for lead content by their determination on the atomic absorption spectrometer “Kvant-2AT”, taking into account the use of the microwave laboratory system PLP-01M and while the sample preparation in accordance with GOST 26929 “Raw materials and food product. Sample preparation. Mineralization to determine the content of toxic elements”. A fundamentally new method of the sample preparation is used in the microwave laboratory system PLP-01M. The decomposition was carried out in a closed system, i.e. sealed fluoroplastic vessels under the influence of high temperature, pressure and microwave field. The microwave field was created by a special generator-magnetron in the operating chamber of the furnace. According to the assessment results of the operational control of the measurement procedure applying samples for the lead control when the microwave laboratory system PLP-01M was introduced in the laboratory; the analysis procedure was found satisfactory.

An assessment of a nutritionally appropriate diet for adolescents’ nutrition

“…A modern human is exposed to numerous stresses associated with an intensive lifestyle, the impact of aggressive factors of man-made habitat [1][2][3][4][5][6], high rates of urbanization, etc. This led to the need to correct a considerable part of the lifestyle, as well as approaches to nutrition.…”

Heavy Metal Contamination of Natural Foods Is a Serious Health Issue: A Review

“…Cobalt (Co), copper (Cu), nickel, iron (Fe), manganese (Mn), zinc (Zn), molybdenum (Mo), and selenium (Se) are vital for living organisms, but can cause serious health complications if consumed above the safe limit [5][6][7][8][9][10]. Other metals such as arsenic (As), cadmium (Cd), chromium, and lead (Pb) are not essential for human health and can cause serious health complications even at low concentrations [11][12][13][14][15][16][17][18][19][20]. Under specific industrial and ecological conditions, metals constitute an important class of toxic substances.…”
