Features of accumulation of trace elements in the soil-honey plants system in the Tyumen region

Abstract

The life activity of living organisms depends largely on the ecological state of their habitat. Based on the environmental monitoring of apiaries in the Tyumen region, the content of chemical elements in the soil and honey plants was studied. Based on the results of assessing the content of trace elements in the soil and plants, the soil contamination coefficient (CO) and the biological absorption coefficient (BAC) of plants were calculated. Studies have shown that the level of chemical elements in the soils and plants of apiaries in certain areas differs significantly. The reason for this is the natural and geographical conditions of these areas, as well as the proximity of anthropogenic sources of pollution. In spring, the content of the studied elements in the soil and in honey plants is higher than in summer. This is due to the fact that the soil receives pollutants that have accumulated in the snow cover during the winter due to atmospheric transport. The analysis of the obtained results showed that apiaries of Tyumen, Yarkovsky and Nizhnetavdinsky administrative districts of the Tyumen region are experiencing the greatest technogenic load. The apiaries of Berdyuzhsky and Sladkovsky districts can be considered environmentally safe. The flowers of coltsfoot (Tussilago farfara L), dandelion, woundwort (Stachus gen.) and willow herb (Epilobium avgustifolium) have a low BAC of the studied elements from honeybees.

“…This method is used to control the operation of treatment facilities. In thermal power engineering, the most often used is "font transparency (by Snellen)", equal to the height of the water column, through which the standard typographic font with a letter height of 3.5 mm is still readable [26,27]. The total stiffness is calculated using the formula (Eq.…”
