The urgency of research is connected with the Astrakhan gas complex functions in a zone of the Volga-Ural sand in territory of east part of the flood of the Volga’s plain. The extracted gas mix contains a plenty of elements in the structure, including the metals. The basic quantity of the metals contains in the passing waters, which after separation put in the underground horizons. Their part remains in the production (gas, sulfur, mineral oil), gas emissions and sewage. During processing raw material 6-8 million м of the sewage is formed in a year with the maintenance, as macro, and microcomponents. One of features of the gas complex is the absence of the dump of sewage in the superficial reservoirs, their recycling is spent on the relief. The basic stream of sewage after the clearing act go in to the capacity of seasonal regulation where it is collected during the cold period of year. From April till October (during the vegetative period), the cleared sewage move on Farmland fields of an irrigation. The irrigation of the steppe vegetation is carried out by overhead irrigation from installations of DM “Fregate”. The given technology can be a source of anthropogenesis influence on ground, vegetation, underground waters and adjoining water-currents in the area of recycling as a result of possible unloading underground waters. In the work the results of the long-term researches of the qualitative and quantitative characteristics of the metals in the sewage, soils and leaves of a wormwood are presented. The comparative long-term analysis of the samples of the irrigated fields selected from the territory has not revealed the tendency to accumulation of the metals. The maximum concentration limit of the investigated elements it is not revealed. The potential ability to accumulation of the metals in the soils is so small, that is connected with the low absorbing ability of the sand.
