The regularity of the mercury pollutant incoming to the soil-woody plants system is discovered The toxicity of the element and its composition depend to a large extent on its bioaccumulation, that is, the mechanism of penetration of the element through the membranes of the plant cell. Selection of soil and plants samples covered the areas of the man-made zone of the Astrakhan gas condensate complex (AGC) and urbanized territories: Astrakhan (the most susceptible to the negative impact of numerous industrial enterprises and transport); and the town Narimanov. Despite it is a small town, it is adversely affected not only by its own sources of pollution, but also by the regional center and the AGC; Kamyzyak, which, according to the wind rose, is least affected by the main sources of possible pollution listed below. The mercury content was determined on a mercury analyzer RA-915. The long-term monitoring of the state of natural objects did not assess the degree of mercury contamination of individual elements of woody plants (root system, bark and leaf crown) of black poplar (Populus nigra L.) and elm (Ulmus pumila L), which actively grow in all areas of the study. To this end, a thorough examination of these woody plants was carried out. The mercury accumulation coefficient was determined. The built-in maps allow to visually examine the distribution of toxic pollutant in the territory of the investigated region in the main organs of poplar and elm.
