The constant selling race results in need for improving the quality of nutrition products among in-house food and pharmaceutical processing industries, which is an all-important key to success on the consumer market. This requires constant improvement of the product producing technologies. The topical problem of quality is the presence of heavy metals and nitroso compounds in the products. The research aimed at studying the changes in the heavy metal concentration levels (including Zn, Cu, Pb) in tomato products at their thickening has been conducted at the national University of Food Technologies. On the basis of the received results the relationship between the lead, copper, zinc, nitrosocompounds and the solid substances’ amount has been established. The conducted research allowed us to ascertain the fact that the amount of heavy metals and nitroso compounds in raw materials for the concentrated tomato products to be ofhigh quality must not exceed the values of 18…35 % of the limiting concentration.

The analysis of literature sources shows that the type and material from which the packaging is made has an important place in the system of factors which influence on the storage of feed products and also prevents reducing the quality of raw materials and finished products. Therefore, the purpose of our research is the technological justification of changing the quality indexes of premix samples with salts of trace elements of different chemical nature in the process of storage. For the solution of the tasks, common zootechnical and statistical methods of the research were used. The use of premixes in feeding pigs is based on the fact that they should be used taking into account the biogeochemical properties of the region for which they are calculated. Foods depending on regional properties have a special biochemical composition and excess or lack of individual substances should be offset by the composition of premix. Ignoring this provision necessarily leads to the inappropriate use of BAR, the misbalance of the diet in relation to the physiological needs and inefficiency of the industry. In turn, it requires the purchase and conservation of products for the period of use. Various chemical structures and structures of BAR during the storage process react differently and change qualitative indexes, which leads to a decrease in the productive activity of active substances. It was determined that the humidity of premixes varied within the limits of 12.0-13.0 %, which exceeded the normative, but was not critical, the highest acidity had premix with sulfuric acid salts (6.9 units), the least - premix with lysates (5.7 unit). According to the results of the study, positive qualitative responses were found for the presence of vitamins A, D and B2, macro- and micronutrients: potassium, magnesium, copper, zinc, cobalt, iodine. The above facts of changes in the properties of premixes in the process of storage must be taken into account when providing technological bases for feeding pigs in order to obtain high gains and the quality of manufactured products. Key words: premix, micro-and macro elements, combined fodders, fodder mixes, chelating compounds, feeding, using, pigs' livestock.

The relationship between the civilisation illnesses and incorrect nutrition can be considered as demonstrated. The functional foods having one or several nutritional- biological advantage can contribute to the healthy nutrition and to improving the quality of life. Beside the healthy nutrition it is an another important requirement that the food does not contain pathogens or substances of chemical and biological origin namely it has to be safe. In this publication the foods of animal origin were investigated in the point of view of public health hazards arising during their production and processing.The contamination and infection of food raw materials, the consequence of chemical substances getting in or developing it the food, the judgement of food deviring from genetically modified or cloned animals are discussed.

Medicinal plants are sources of nutrients, may contain one, two or more active ingredients that can provide certain medicinal properties in a living organism. Such plants include milk thistle, which is gaining popularity. Today, the quality of medicinal raw materials is relevant, because milk thistle has a high intensity of accumulation of various toxicants. Recently, this plant has been grown in field crop rotations, the soils of which are contaminated with various toxicants, including heavy metals. Therefore, there is a need to study the intensity of heavy metal contamination of milk thistle, grown in agricultural crop rotations. Milk thistle has biologically active substances, macro- and microelements in the most accessible and digestible form and is one of the factors of the positive effect of its use in medicine, pharmacology, food industry, animal husbandry and crop production. Toxic substances have a negative impact on the quality of medicinal raw materials, can accumulate in plants due to man-made pressure on the environment. These toxicants, entering the human and animal body, can interact with proteins, nucleic acids, change the activity of enzymes, disrupt their biological and transport properties, which can ultimately lead to negative consequences. The influence of mineral fertilization of milk thistle on the intensity of copper accumulation in its leaf mass and seeds has been studied. It was found that when feeding milk thistle with mineral fertilizers, there is an increase in leaf mass and copper seeds. In particular, for the use of ammonium nitrate - 1.25 and 1.4 times; superphosphate simple - 1.14 and 1.2 times; potassium chloride - 1.16 and 1.2 times; mixtures of NPK fertilizers - 1.53 and 1.1 times. Key words: heavy metals, intensity, copper, mineral fertilizers, milk thistle, concentration, danger coefficient, accumulation coefficient.

It is well-known that melliferous bees are the most sensitive indicators of ecologic conditions of natural environment. Researches in recent years show that bees and bee products can accumulate selectively some heavy metals, radioactive substances, pesticides and other polluters. Scales of heavy metals accumulation on the territory of Ukraine, as toxins of technologic origin unfortunately increase. Environmental pollution by heavy metals leads to their accumulation in plant and animal raw materials and production, consequently their quality decreases. It was proved that apiary accommodation in heavy metal polluted territories leads to their accumulation in pollen, honey bee-comb and wax. But the questions concerning study of peculiarities of sources, ways of pollution and heavy metals content in bee products are not enough lightened, and that was the purpose of our work. Generalized we present in literature information and results of our researches about the use of bees and bee products in quality of bioindicator contamination of environment by heavy metals. Dependence of content of heavy metals is set in the organism of bees in relation intensity of greening to contamination of environment. It is marked on the necessity of lead through of systems research in relation to determination of content of heavy metals in fabrics of bees and bee products with the purpose of search of new methodological approaches for authentication these toxicant of objective environment of contamination and him apimonitoring. Methodological elements of the researches of regularities of heavy metals and lipids content in the tissues of different anatomic sections of the organism and bee products were elaborated.

Mosaic sludge is sewerage from mosaic industrial activities such as cutting, polishing and grinding. This sludge mostly will be disposed directly to landfill and some of it was discharged in drainage system without proper treatment. Therefore, in this study, mosaic sludge from the mosaic industry were reused and incorporated into fired clay brick in order to provide alternative disposal method, producing adequate quality of brick as well as minimizing the heavy metal leachability to the environment. First, X-Ray Fluorescence (XRF) was conducted to determine the heavy metal concentration from two types of mosaic sludge. The results indicate that the highest element concentration in mosaic sludge (BS and PS) shows that Barium is the highest with 3253ppm and 3260ppm. On the raw sludge, the lowest obtained in BS and PS is Cesium with 14ppm and 17ppm. SPLP and TCLP also conducted in this study and the results show that, even though the element such as ferum (Fe) and cadmium (Cd) was not detected in XRF but in SPLP and TCLP, it shows that these two elements exist in clay, BS and PS with low concentration. In term of properties, compressive strength was conducted by incorporating 0%, 1%, 5%, 10%, 20% and 30% bodymill and polishing sludge into fired clay brick. The results show that compressive strength of BS brick was stronger than PS brick. Lastly, Static Leachate Test (SLT) was conducted to measure the long term leachability of heavy metals from different percentages of mosaic sludge brick. In SLT result, ferum (Fe) shows the highest value of heavy metal concentration among other elements. The results for control brick, BS brick and PS brick show the same pattern and far from the limit set by USEPA.

Biophile microelements (copper, zinc, manganese, iron, nickel) and heavy metals (lead, cadmium) in the aerial part of Artemisia frigida Willd. and Artemisia jacutica Drob. of Russian (areas of the Republic of Buryatia) and Mongolian flora was presented in this paper. The quantitative content of the elements in the samples collected in 2008, 2015–2018 was studied using atomic absorption method performed on a SOLAAR M6 after preliminary decomposition by dry mineralization, and inductively coupled plasma atomic emission method (ICP) on a Profile Plus spectrometer after decomposition of samples in the MARS 6 microwave system. The content of the same elements in the aerial part of the same species of Artemisia varied in a wide range, which was consistent with the literature data. In addition, the Principle component analysis of the elemental composition of A. frigida and A. jacutica was presented in this paper. The biplot showed the impact of forest fires that took place on the territory of Buryatia in 2015. So this year was characterized by a high concentration of lead, cadmium, nickel, copper and iron in studied samples. Also, the biplot showed the elements content versus plant species. In general, the content of toxic (lead, cadmium, nickel) and vital elements (copper, zinc, iron, manganese) was within the normal concentration. Therefore, the aerial part of A. frigida and A. jacutica of Buryatian (Russia) and aimaks (Mongolia) flora can be considered as promising plant raw materials for using in medical practice.

Annotation. The Voronezh region is traditionally the most important area of crop production and farming. The purpose of the study was to study the contamination by heavy metals of medicinal vegetable raw materials of the Voronezh region on the example of the grass of the five-plant desert collected in urban and agro-ecological systems, which experience different anthropogenic effects. The accumulations of heavy metals (lead, mercury, cadmium, nickel, copper, zinc, cobalt, chromium) and arsenic were studied, in 51 samples of five-layer desert grass. Comparing the data on heavy metal content in the upper soil layers of the region and the content of these elements in the grass of the five-layer desert, it can be assumed that there are significant physiological barriers to the accumulation of ecotoxicants in the generative organs of the plant, which is particularly noticeable for elements such as lead, mercury, arsenic, cadmium, cobalt and chromium. The five-point desert is able to selectively concentrate some heavy metals entering the active centers of enzyme systems (such as copper and zinc) if their environmental content is below some vital level; With a significant content of these elements in soils, the plant also physiologically blocked their entry into the leaves. Thus, for a five-layer desert under anthropogenic load conditions, an edaphotype is formed as a result of the action of selection under conditions of man-made pollution of the external environment and the manifestation of adaptation to these conditions. The results of studies have shown that the grass of the five-plant desert is able to accumulate toxic elements from soils, which is important in planning the places of production of medicinal vegetable raw materials and assessing its quality.
