Environmental monitoring of selected metals was performed using biota and soil samples. Sampling was carried out during the period March-May and October-November. For the isolation of these analytes, conventional extraction and microwave mineralization techniques were applied. Atomic Absorption Spectroscopy (AAS) equipped with Graphite Furnace (GF) was used to determine heavy metals and macroelements. The obtained data were compared with the respective values recommended by the Polish Standards. Popular bioindicators were used to estimate the level of pollution by heavy metals of Torun, Poland. Application of the established sampling procedures for environmental samples and determination methods for xenobiotics can be successfully applied for the purpose of routine analyses in biomonitoring.
