Environmental pollution is a major problem nowdays. Because of his desire for development man carelessly, perhaps even unknowingly destroys the environment and its components, almost to an irreversible state, not caring eather about the future or for the needs of his descendants for the clean and healthy environment. Therefore, more attention is paid to the development of environmental protection methods and procedures. In addition to standarda methods of sampling and analysing air, water and soil, scientists are increasingly turning to cheaper and more accessible environmental state indicators. In order to monitor changes in the environment in the most acceptable way, biomonitoring is introduced. Iti s a monitoring method in which scientists use biomaterials such as bees, honey, shellfish, mosses, lichens, fungi to monitor the state of the environment under the influence of contamination and to monitor how contamination impacts the species of selected biomaterial, as well as the ecosystem as a whole. In biomonitoring, biomaterial samples are taken, then prepared appropriately and subjected to standard contaminant determination techniques. Based on the given results, a clear idea can be obtained about the present state of the environment, the sources of contaminants as well as their impact on flora, fauna and, ultimately, on man himself.
