“…Water conductivity was low in spring from 39 μS/cm in the Dim River to 120 μS/cm in the Arguzikha River, in summer specific conductivity increased from 179 μS/cm in the Dim River to 300 μS/cm in the Gilchin, Manga and Arguzikha Rivers. Water in small rivers of the Zeya-Bureya Plain is characterized by low mineralization [2,3]. Low values of water hardness and mineralization affect the mobility of heavy metals and contribute to an increase in bioaccumulation [4].…”

“…Birds respond to changes in the environment, they can accumulate pollutants from the atmosphere, soil and water. The accumulation of microplastics [16], agricultural chemicals [17], heavy metals and other pollutants [2,3] in various tissues and organs of birds has been studied. Accumulation of heavy metals has been studied in blood, liver and muscles, bones of birds [18], in egg shells, and in feathers of birds [2,3,19,20].…”

“…The accumulation of microplastics [16], agricultural chemicals [17], heavy metals and other pollutants [2,3] in various tissues and organs of birds has been studied. Accumulation of heavy metals has been studied in blood, liver and muscles, bones of birds [18], in egg shells, and in feathers of birds [2,3,19,20]. Different bird species, differing in lifestyle and type of diet, are studied, but the most important are studies on the determination of heavy metals in the habitat of endangered wetland birds [2, 3, 19 -22].…”

From 2019 to 2021, the content of heavy metals in the components of the aquatic ecosystem, which is the habitat of birds on the territory of the Zeya-Bureya plain, was studied (water, sediments, macrophytes, bird feathers). High levels of iron and manganese were found in the water of small rivers. Due to heavy rains and floods, heavy metals were washed out of the surface layers of soil in agricultural fields into rivers. High concentrations of copper and lead were found in the bottom sediments of small rivers. Agricultural pollution of aquatic ecosystems affected the accumulation of lead and manganese in macrophytes. Bird feathers contained the highest amounts of iron, zinc, copper, and manganese, and the lowest amounts of cobalt and cadmium. The feathers of protected bird species such as Swan Goose, Red-crowned Crane, Hooded Crane and Daurian white-naped Crane contained lead 13.5 -38.2 mg/kg, cadmium 0.17 - 0.51 mg/kg. The elements in the feathers of birds were of exogenous origin. Birds are bioindicators of anthropogenic pollution. Researches in this direction are necessary for an estimation of ecological risk of environment and acceptance of measures on its protection.

The research featured fortified fermented drinks from pasteurized buttermilk with such natural additives as Jerusalem artichoke syrup and beetroot dietary fiber. The optimal symbiotic culture included Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus: it provided rapid fermentation and a creamy, homogeneous structure with delta pH time = 3.5 h. Jerusalem artichoke syrup was added in amounts of 3, 6, and 9%. Its optimal share proved to be 6% by the weight of the finished product. Beet dietary fiber was added in amounts of 2, 4, and 6%, where the optimal amount was 4%. A higher percentage affected the consistency of the finished product but not its clotting or taste. The experimental drinks were produced by the tank method and fermented at 42 ± 2°C until dense clotting and titratable acidity = 72 ± 2°T. The finished product was stored at 4 ± 2°C. The shelf-life was 12 days for the sample with Jerusalem artichoke syrup and 14 days for the drink fortified with beetroot fiber. The physical and chemical indicators showed that the energy value of the fortified fermented buttermilk drinks was on average 45.3% lower compared to conventional fermented dairy drinks. As a result of research, it has been established that the use of plant components, namely Jerusalem artichoke syrup and beet dietary fiber in the production technology of fermented milk drink from buttermilk makes it possible to obtain a finished product with improved consumer properties.
