- Abstract
The main aim of this study was to determine the concentrations of cadmium in soils in municipal parks of Wrocław, as well as the assessment of soil contamination with this element. Examined were the soils of lawns within three municipal parks: Szczytnicki, Zachodni and Południowy. In each of them, 4 areas of ca. 100 m2 were selected, from which representative soil samples were collected form the layers 0-5 cm and 5-15 cm. Basic properties of soils were determined, and the concentrations of Cd were measured by ICP-AES, after digestion in concentrated HNO3 + HCl. Cadmium concentrations in soils varied considerably, both among, and within the parks. The highest concentrations of this element (13.5, and 4.56 mg·kg-1, in the layers 0-5 and 5-15 cm, respectively) were found in one of areas in the Zachodni Park, where the value of soil quality standard was exceeded. Cadmium concentrations in the other areas and parks were much lower, and median values, that best illustrate the average concentrations of Cd in the soils examined, were close to natural: 0.42 and 0.28 mg·kg-1.
