MASTER'S DISSERTATION ANNOTATION
Substantiation of the dissertation and relevance of the topic. Plants are actively involved in the migration and transformation of chemical compounds on the Earth's surface. The intensity of biogenic migration of chemical elements is determined by the chemical composition of plants. The study of the elemental composition of plants is necessary to more fully describe the distribution of chemical elements in natural and anthropogenic landscapes, as plants are the most important link in the biological cycle of matter. From a practical point of view, information about the chemical composition of plants is necessary for a balanced diet of humans and animals.
Dry plants contain chemical elements found in the air, water and soil. The bulk of plants (usually 90-95% of their dry weight) are the three elements assimilated by photosynthesis: carbon, oxygen, and hydrogen, which are absorbed by plants from air and water. The remaining 5-10% of plant matter is mineral elements (nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, silicon, iron, sodium, chlorine, aluminum, trace elements) from the soil. The chemical elements in the plant body are unevenly distributed. For example, the highest concentrations of elements are found in leaves and needles. The main functions of the leaves of this green plant are photosynthesis, transpiration and the synthesis of various organic compounds. The distribution of minerals in grasses is more or less equal in plants. Increased levels of manganese, copper, molybdenum, and boron in the reproductive organs and fruits are common.
In general, the healing properties of plants, their use in traditional and folk medicine, due to the presence of biologically active substances of both organic and mineral origin. However, the properties of organic compounds (flavonoids, alkaloids, amino acids) and their effects on the body are often studied. However, the elemental composition of plants has not been studied. Plants are sources of macro- and micronutrients, which accumulate in specific, often significant, concentrations. Therefore, plants are used as a prophylactic and therapeutic agent in the treatment of nutrient deficiencies. On the other hand, it is important to know the concentration of the elements when comparing them with acceptable values ​​to ensure that herbal preparations are not toxic. Thus, information on the composition of essential and conditionally toxic elements in plants is necessary for their rational use in medical practice.
