Abstract
The sorption abilities of seven moss species growing on the area of Bory Stobrawskie forest (southern Poland) were tested in laboratory. Sorption was carried out in solutions of Zn and Cd chlorides. It has been shown that the sorption properties depend on the moss species and increases in the series as follows: Polytrichum commune < Leucobryum glaucum < Eurhynchium praelongum < Thuidium tamtariscifolium ≤ Dicranum scoparium ≤ Pleurozium schreberi < Sphagnum sp. With help of microscope images, it was also demonstrated that one of the factors affecting the sorption properties of mosses was the level of their surface development. The determined sorption capacity of Zn varies according to species of mosses from 0.0491 to 0.1287 mmol g−1, and in relation to Cd from 0.0319 to 0.1335 mmol g−1. The described results may be important in the process of biomonitoring research design and in the test results interpretation.

Summary
The sorption abilities of seven moss species growing on the area of Bory Stobrawskie forest (southern Poland) were tested in laboratory. Since 1990, many European countries have been conducting cyclic (carried out every 5 years) research on trace elements accumulated in mosses. Due to a large extent of biomonitoring research, the above studies incorporate various species of mosses having different sorption properties and in the case of comparative studies, false conclusions can often be drawn. The aim of the study was to evaluate the sorption properties of seven species of mosses exposed to the presence of xenobiotic (Cd) and trace element (Zn) and to check if in natural conditions different species of mosses absorb the tested metals in accordance with the proportions experimentally determined in the laboratory
