ABSTRACT
In laboratory tests we have found that the sodium arsenite has high mobility in the upper contaminated layer of soil in the simulation of atmospheric effects such as rain precipitation [1, 2]. This is primarily due to the fact that the sodium arsenite is a highly soluble compound. In addition, arsenic in sodium arsenite is in anionic form, which also affects the ion exchange processes in soils. We have shown that cationic forms of metal are kept better in soil [3, 4]. Anthropogenic impact of sodium arsenite on the soil could be in the works for the destruction of lewisite in Kambarka Udmurt Republic in 2006-2009, as it is a product of the decomposition of this toxicant by alkaline hydrolysis [5, 6]. Therefore, investigation related to the definition of the mobility parameters of sodium arsenite in soils Kambarka district is of interest. These data can be used both in the development of environmental monitoring and sanitation of contaminated areas [7].
