Determination of the content of heavy metals in liquid phase of snow by X-ray florescense method

The possibility of determining the total content of heavy metals in the liquid phase of snow was researched by X-ray fluorescence analysis with preconcentration of elements determined by sorption DETATA filters. Optimal conditions for the analysis, providing a minimum error of determination have been chosen and justified. The contribution was made by the stage of concentration in the overall error of the method. A pollution monitoring of snow cover in the five districts of Samara was carried out.
