Comparison of Total Content of Zinc and Arsenic in Soils of Średzka Upland and Wrocław Ice-Marginal Valley

The aim of this study was to demonstrate that alluvial sediments of Wrocław ice-marginal Valley are characterized by higher con-centrations of metallic elements in relation to the adjacent areas of different soil cover genesis.

Studies of zinc and arsenic content in soils were carried out in six municipalities of Średzki district. A total of 117 soil samples from arable land was collected: 80 from Średzka Upland and 37 from Wrocław ice-marginal Valley

The process of accumulation of heavy metals in alluvial sediments in the Wocław ice-marginal Valley is so effective that, despite the heavier grain size composition of the soil cover immediately adjacent to Średzka Upland, zinc and arsenic concentrations are higher in the alluvial soils.
