The data about alternative of As phytotoxicity influence elimination on agricultural crops in the As+S complex are presented. Both short-time laboratory and pot experiment methods were used. The high phytotoxicity of As is persisting in the whole vegetation period. At a short-time exposure, toxic effect of the As+S complex is lower that the As toxic effect alone. A significant increase of barley yields as well as a decrease of the As content in the horse bean dry matter was founding out after the As+S complex treatment. In conclusion, a sulfate treatment is one alternative of the As elimination on agrophytocenoses in heavy metal polluted areas
