Purpose. Determine the content of heavy metals in the grain of spring barley varieties of different application as affected by the duration of storage. Methods. In the years 2018–2020, 11 spring barley varieties of different applications were studied: grain ‘Stalker’, ‘Vodohrai’, ‘Vzirets’, ‘Ahrarii’, ‘Shchedryk’; universal ‘Enei’; malting ‘Kozak’, ‘Dokuchaievskyi 15’, ‘Etyket’, ‘Helios’, ‘Sviatohor’. The content of chemical elements in the grain (cadmium, lead, mercury, arsenic, copper, zinc) was determined in the dynamics: immediately after harvest, after 7, 14, 21 and 28 days. Results. In the studied varieties of spring barley, the lead (Pb) content in the grain varied immediately after threshing and after 7 days ranged from 1.01 to 1.12 mg/kg. Reduction of the studied element after 14 days was observed in all varieties. In particular, the lead content was 1.03 mg/kg in ‘Shchedryk’, 1.01 mg/kg in ‘Stalker’, 1.00 mg/kg in ‘Vzirets’, 0,78 mg/kg (the lowest) in ‘Vodohrai’, and 1.12 mg/kg (the highest) in ‘Ahrarii’. Studies have shown that the most sensitive to cadmium (Cd) grain variety of spring barley was ‘Vzirets’ with the content of 0.09 mg/kg immediately after threshing and on the 7th day of storage; on the 14th, 21st and 28th days, the content was 0.08 mg/kg. The content of cadmium in malting barley grain immediately after threshing and after 7 days was 0.08 mg/kg in ‘Sviatohor’, and 0.09 mg/kg in all other varieties. On the 14th day, the accumulation remained unchanged in varieties ‘Dokuchaievskyi 15’, ‘Etyket’, ‘Helios’, ‘Sviatohor’; insignificant decrease was noted in ‘Kozak’ (0.07 mg/kg). After the storage for 21 and 28 days, the cadmium content was 0.07 mg/kg in ‘Sviatohor’ and ‘Kozak’, and 0.08 mg/kg in all others. Conclusions. The lowest cadmium content was determined in variety ‘Shchedryk’. Immediately after threshing and after 7 days of storage it was 0.05 mg/kg, and on the 14th, 21st and 28th days it decreased to 0.03 mg/kg. Immediately after threshing and after 7 days, the mercury content of the varieties varied from 0.07 to 0.03 mg/kg. After 14, 21 and 28 days, the following values were determined: in ‘Vodohrai’ 0.06 mg/kg, in ‘Stalker’ and ‘Vzirets’ 0.05 mg/kg, in ‘Ahrarii’ 0.04 mg/kg, ‘Shchedryk’ 0.3 mg/kg. Depending on the varietal characteristics and duration of storage, the highest content (14.05 mg/kg) was determined in ‘Ahrarii’, and the lowest (12.55 mg/kg) in ‘Shchedryk’. The study of the ‘Enei’ variety of spring barley of universal application allows us to note that the accumulation of heavy metals, as affected by the duration of storage, did not differ significantly from the grain varities.

ABSTRACTIn muscle and livers of steers given a diet with sodium monensinate a significant decrease in cadmium content was observed. The concentration of manganese, copper, zinc, lead and iron in the analysed organs varied inconsistently. It seems from the results that, in tissues, monensinate influences the metabolism not only of monovalent cations but of polyvalent cations as well.

Total number of 104 canned soft drinks collected from several regions in Turkey were analysed. The purpose of this study was to determine the levels of heavy metals in the drinks commonly consumed in Turkey. Quantitative determination of heavy metals: arsenic, copper, zinc, cadmium, and lead in all samples was carried out by ICP-OES (Inductively Coupled Plasma-Optical Emission Spectrometry) method. The mean levels (± SE) of arsenic, copper, zinc, cadmium, and lead were found to be 0.037 ± 0.002 mg/kg, 0.070 ± 0.009 mg/kg, 0.143 ± 0.012 mg/kg, 0.005 ± 0.0003 mg/kg, and 0.029 ± 0.002 mg/kg, respectively, in soft drinks. Our data revealed that arsenic, copper, zinc, cadmium, and lead mean levels found in all soft drinks, collected from several regions in Turkey, were within the Turkish Food Codex (TFC) values.

Wood biofuel ash is a complex and heterogeneous mixture of inorganic crystalline and amorphous minerals together with organic matter. Biofuel ash is usually enriched with K, P, Ca and Mg, which are essential macronutrients for plant growth. Currently, a large proportion of biofuel ash is disposed of in landfills. However, ash processed into granular products can be used as a stand-alone or additional mineral fertilizer in agriculture. The aim of the research is to determine the chemical composition of biofuel ash and evaluate its suitability for the production of ash granules; also to evaluate the yield of spring barley grain and straw fertilized with bulk and granular biofuel ash, and the correlation between the yield and the amount of K2O applied by different fertilization products. The experiment was carried out in 2017–2018. Concentrations of heavy metals (Cr, Pb, Ni, Cd) and microelements (Zn and Cu) in wood biofuel ash did not exceed the permissible norms, and from them it was possible to produce fertilization products (ash granules) and use them in a vegetation experiment. During the experiment, it was found that the fertilization products significantly (P < 0.05) increased the yield of grown spring barley grains and straw in both years of the study, and the performed correlation regression analysis was positively strong in both years of the study (P < 0.01). The yield of spring barley increased with the increase of K2O content in fertilizer products.

Environmental pollution, especially by chemical substances, is one of the most powerful factors in disrupting components of the biosphere. Currently, the biosphere receives a lot of pollutants. Among them are significant heavy metals. Among the chemical elements, heavy metals are the most toxic. The danger of increasing the content of heavy metals in the soil and heavy metals in the atmosphere is associated with active absorption and accumulation of plants, which not only negatively affect their active actions, but also threaten human and animal health. The danger of metals is that they have a cumulative effect and retain these toxic properties for a long time. In connection with the task of studying the gene pool of cultivated plants in the conditions of technogenic pollution, the study of metal resistance of barley varieties was carried out in order to identify promising forms for growing in the East Kazakhstan region, as well as breeding donors that collect the minimum amount of pollutants. The results obtained allow us to suggest donors resistant to heavy metals that can be used in breeding and genetic research. Barley is a concentrated product for animals, as the composition is rich in starch and protein. Barley seeds, along with amino acids, protein, lysine and tryptophan, which cannot be replaced by another substance, are preserved better than in other crops. Barley in Kazakhstan ranks second after wheat. The East Kazakhstan region is favorable and in demand for growing barley. However, the damage to the vessels by heavy metal affected the commissioning of the product. The most effective way out of this is to prevent the genetic and physiological effects of the genes of these tolerant (hardy) species. Genotype identification is a new and unexplored area of invention for products that grow against heavy metals in plants.

Contamination of the food chain with heavy metals has become an urgent problem in recent years due to their potential accumulation in biosystems and is related to increased anthropogenic impact. This study assessed the levels of cadmium, lead, copper and zinc in cattle from the Novosibirsk, Krasnozersk, and Maslyanino regions of the Novosibirsk region and the Tselinny region of the Altai region. The aim of the study is to assess the influence of the ecological and geographical factors on the content of heavy metals in the spleen of Hereford gobies. Spleen samples were taken from 31 clinically healthy Hereford bulls aged 16-18 months. Sample preparation was carried out in accordance with GOST 26929-94 and 30178- 96. The determination of the chemical composition of the samples was carried out by atomic absorption spectrometry with flame and electrothermal atomization. The median values for the content of copper, zinc, lead and cadmium in the spleen of bull calves bred in Krasnozersky, Maslyaninsky, Novosibirsk and Tselinny regions were in the range of 1.6-1.8; 21.0-22.4; 0.06-1.45; 0.01-0.09 mg / kg. The phenotypic variability of the level of copper and zinc was relatively low, while that of lead and cadmium was high. The influence of the ecological and geographical factor was characteristic only for the level of cadmium. Significant differences in the concentration of cadmium in the spleen in animals raised in the Maslyanino region from those bred in the Krasnozersk and Novosibirsk regions were revealed. For copper, zinc and lead reference intervals were calculated - 0.60-2.92; 17.2-26.0; 0.019-0.218 mg / kg, respectively. They can serve as a rough guideline for Hereford cattle bred in the Krasnozersk, Novosibirsk, Maslyanino districts of the Novosibirsk region and the Tselinny district of the Altai region.

The paper present result of research on the intensity of the absorption of cadmium from the soil by plants barley. The object of the study were plant spring barley varieties Peas in various stages of development. Сadmium was added to the soil (dark-grey podzolic) as a CdCl2·2,5H2O in the concentration of 3, 15 and 30 mg Cd+2 per kg of the soil. Сadmium is one of the heavy metals which occur in the environment as a result of antropogenic activities. The best solution for maintaining non-contaminated soils and plants is to remove the sources of Cd in the environment. Given that that is essentially impossible at this time, further research needs to determine how soil and plant factors affect Cd availability on polluted soils. Of all non-essential heavy metals, Cadmium (Cd) is perhaps the metal that has attracted the most attention in soil science and plant nutrition due to its potential toxicity to humans, and also its relative mobility in the soil-plant system. The Cadmium is for plants completely unnecessary element. Of particular concern for humans are the high concentrations of Cd in grain. Established that the Cadmium content in barley amended as follows: underground faction > vegetative biomass fraction > generative fraction (control and on the variant of contamination of soil in a dose 3 mg Cd+2 per kg of the soil) and underground faction > generative fraction > vegetative biomass fraction (on the variants of experience 5 and 10 maximum possible concentration of Cd+2). Сadmium absorbed most intensive barley in the flowering stage. Cadmium is characterized by subzero migratory ability in theorgans of barley. Roots are the main accumulators of this heavy metal. Every stress conditions are signal for a plant to initiate in its cells a number of different biochemical processes (e.g. changes of cytoplasm pH, changes of electrostatic potential of cell membranes, flow of ions). It is set that getting a clean straw and clean grain ispossible only on the variants of experien-ce 1 maximum possible concentration of Cd+2 and on control. The effect of сadmium and other heavy metals on plants depends not only on its form, but also on the presence and concentration of other elements and substances, the plant species and its developmental stage are also important. Several soil conditions, such as the pH value, calcium level, content of organic substances, particulaly humus etc., are decisive for the exchangeable and water soluble, available сadmium for plants.

Abstract Introduction: Hard antlers of deer are unique bioindicators of environmental metal pollutions, but sampling methods presented in the literature are inconsistent. Due to the specific growth pattern of antlers and their histological structure, sampling methods described in the literature were reviewed, the suitability of using mixed samples of both antler layers as element bioindicators was assessed, and the codified method of antler sampling used for bioindication was described. Material and Methods: Lead, cadmium, mercury, arsenic, copper, zinc, and iron in trabecular and cortical parts of hard antlers of red deer (Cervus elaphus) were determined using different methods of atomic absorption spectrometry (depending on the element). Results: Mean mercury content in trabecular bone (0.010 ±0.018 mg/kg) was 5 times higher than in cortical bone (0.002 ±0.003 mg/kg). Mean iron concentration was approximately 15 times higher in trabecular (239.83 ±130.15 mg/kg) than in cortical bone (16.17 ±16.44 mg/kg). Concentrations of other analysed elements did not differ statistically between antler layers. Conclusion: In mixed antler samples, concentrations of mercury and iron depend on the particular antler layer contents. This therefore warrants caution when comparing results across studies and specification of the sampling methodology of antlers is highly recommended.
