Magnetite (Fe2+Fe3+2O4) is an iron-bearing mineral with magnetic properties. Mostly it is obtained in its natural form. The purpose of our study is to study the effect of magnetite on health. At the first stage of research, we carried out X-ray fluorescence and X-ray phase analyzes of sand taken from beaches with magnetic and non-magnetic sand on the Black Sea coast, namely from the beaches of Ureki and Chakvi.It can be seen from the research results that the sands of Ureki and Chakvi differ in composition, this difference is not only in magnetite, but in the sand of Ureki (in the crystalline phase) there are two spar, and in the sand of Chakvi only one. However, there is more quartz in the sand taken from Chakvi than in the sand of Ureki.The rare composition of Ureki sand is likely to determine the health effects we plan to study in the next phase of our research.

In the region of Bolnisi-Dmanisi, mineral extraction is carried out, where the certificate (ISO) is not maintained and the environment is polluted. Quantitative study of heavy metals, in particular cadmium, in this area shows that an increase in the concentration of cadmium is observed along the coastline of the Mashavera river, which poses a threat to human health. Aim of the study: monitoring of the content of cadmium in the water of the river Mashavera in the region of Bolnisi-Dmanisi. Monitoring in 2021-2022 revealed that the concentration of the heavy metal cadmium in the Mashavera river is increased, especially in the summer period in the settlements located near the quarry. The fact is very remarkable and requires the adoption of appropriate measures, as the population uses this water for irrigation, and the cadmium contained in the water accumulates in the vegetables, the population uses vegetables for food. The accumulation of cadmium in the human body is a risk factor for the development of acute or chronic diseases.

Radiation from a cell phone causes significant changes in a living organism. Pregnant women and children belong to the most sensitive groups of population and are particularly vulnerable to electromagnetic field radiation. We decided to study the concentration of growth hormone 2 (GH-2) in pregnant rats exposed to electromagnetic field (1800 MG/H), what the effect of electromagnetic field as a negative stimulus on offspring weight, number and development would be. Irradiation of rats during pregnancy with an electromagnetic field has shown that GH2 hormone decrease and it causes retardation of offspring, shortening of the limbs and tail of newborn rats compared to controls, and that control rats' eyes open earlier than those of experimental rats and consequently weight loss in rats in the experimental group. The public, especially pregnant women, should be aware that the electromagnetic field negatively affects not only their health, but also the fetus, causing certain changes.

Bacterial spread in fish gills and muscles with mesophilic aerobic and facultative-anaerobic microorganisms. These microorganisms are caught in 4 points of the river Alazani which depends on seasonal eutrophication of the water ecosystem. It also depends on the existence of microorganisms. In summer months when water gets warm and, at the same time, chemical and fecal masses flow into the water, the amount of microorganisms increase. As the temperature of the water decreases towards autumn-winter, rains increases which leads to reservoirs dilution and decrease in organic substances. They mostly occur in suspended condition and their amount in water decreases and thus in fish gills and muscles.
